	title = {Permafrost Terrain Dynamics and Infrastructure Impacts Revealed by {UAV} Photogrammetry and Thermal Imaging},
	abstract = {Unmanned Aerial Vehicle ({UAV}) systems, sensors, and photogrammetric processing techniques have enabled timely and highly detailed three-dimensional surface reconstructions at a scale that bridges the gap between conventional remote-sensing and field-scale observations. In this work 29 rotary and fixed-wing {UAV} surveys were conducted during multiple field campaigns, totaling 47 flights and over 14.3 km2, to document permafrost thaw subsidence impacts on or close to road infrastructure in the Northwest Territories, Canada. This paper provides four case studies: (1) terrain models and orthomosaic time series revealed the morphology and daily to annual dynamics of thaw-driven mass wasting phenomenon (retrogressive thaw slumps; {RTS}). Scar zone cut volume estimates ranged between 3.2 × 103 and 5.9 × 106 m3. The annual net erosion of {RTS} surveyed ranged between 0.35 × 103 and 0.39 × 106 m3. The largest {RTS} produced a long debris tongue with an estimated volume of 1.9 × 106 m3. Downslope transport of scar zone and embankment fill materials was visualized using flow vectors, while thermal imaging revealed areas of exposed ground ice and mobile lobes of saturated, thawed materials. (2) Stratigraphic models were developed for {RTS} headwalls, delineating ground-ice bodies and stratigraphic unconformities. (3) In poorly drained areas along road embankments, {UAV} surveys detected seasonal terrain uplift and settlement of up to 0.5 m ({\textgreater}1700 m2 in extent) as a result of injection ice development. (4) Time series of terrain models highlighted the thaw-driven evolution of a borrow pit (6.4 × 105 m3 cut volume) constructed in permafrost terrain, whereby fluvial and thaw-driven sediment transfer (1.1 and 3.9 × 103 m3 a−1 respectively) was observed and whereby annual slope profile reconfiguration was monitored to gain management insights concerning site stabilization. Elevation model vertical accuracies were also assessed as part of the case studies and ranged between 0.02 and 0.13 m Root Mean Square Error, whereby photogrammetric models processed with Post-processed Kinematic image solutions achieved similar accuracies without ground control points over much larger and complex areas than previously reported. The high resolution of {UAV} surveys, and the capacity to derive quantitative time series provides novel insights into permafrost processes that are otherwise challenging to study. The timely emergence of these tools bridges field-based research and applied studies with broad-scale remote-sensing approaches during a period when climate change is transforming permafrost environments.},

	title = {Sources and cycling of dissolved organic carbon across a landscape of arctic delta lakes},
	abstract = {Dissolved organic carbon ({DOC}) is a key regulator of aquatic ecosystems, and the primary substrate for aquatic bacteria. However, variations in function between different {DOC} sources are rarely studied. Arctic Mackenzie Delta lakes exhibit striking differences in {DOC} composition, with {DOC} sources ranging from C produced as a byproduct of aquatic plant (macrophyte) photosynthesis, to C derived from permafrost melting (thermokarst), and C delivered to lakes via river-water. This study assessed how variations in {DOC} source regulate the composition of the within-lake pool, drive bacterial metabolism and the contribution of bacterial biomass to higher trophic levels, and affect {CO}2 flux from Delta lakes. {DOC}-specific tracers showed macrophyte-derived {DOC} to comprise less than 15\% of the {DOC} pool in macrophyte-rich lakes, despite macrophyte C levels 7-12-fold greater than total {DOC}. However, bacterial δ13C indicated that bacteria preferentially incorporate {DOC} generated by macrophytes, while surveys and incubation experiments showed that bacterial metabolism is rapid on macrophytic {DOC}, with high rates of bacterial biomass production relative to respiratory loss as {CO}2. Accordingly, δ13C, δ15N, and fatty acid biomarkers demonstrated that zooplankton from macrophyte-rich lakes receive a greater proportion of their biomass from bacterial organic matter than zooplankton from other lake types. At the same time, however, experiments indicated that the high {pH} resulting from rapid photosynthesis in macrophyte-rich lakes can decrease the rate of bacterial metabolism over the short-term, and increase {CO}2 respiration at the expense of bacterial biomass production. In contrast, {DOC}-specific tracers indicated that thermokarst-derived {DOC} accumulates in lakes. Incubation experiments and in situ surveys revealed thermokarst {DOC} to be a relatively poor bacterial substrate, which resulted in proportionately more {CO}2 respiration, relative to bacterial biomass production, than observed for other Delta {DOC} sources. Moreover, multi-year surveys demonstrated that thermokarst lakes exhibit high levels of {CO}2 emission, despite clear undersaturation in other lakes, presumably because permafrost-derived {DOC} was largely respired by bacteria. Understanding the divergent roles played by the contrasting sources of {DOC} to Delta lakes both adds insight to the functioning of other lake regions, globally, and helps clarify the effect of climate-induced changes in {DOC} on northern lakes.},

	abstract = {Dissolved organic carbon ({DOC}) is a key parameter in lakes that can affect numerous features, including microbial metabolism, light climate, acidity, and primary production. In an attempt to understand the factors that regulate {DOC} in lakes, we assembled a large database (7,514 lakes from 6 continents) of {DOC} concentrations and other parameters that characterize the conditions in the lakes, the catchment, the soil, and the climate. {DOC} concentrations were in the range 0.1–332 mg L−1, and the median was 5.71 mg L−1. A partial least squares regression explained 48\% of the variability in lake {DOC} and showed that altitude, mean annual runoff, and precipitation were negatively correlated with lake {DOC}, while conductivity, soil carbon density, and soil C:N ratio were positively related with lake {DOC}. A multiple linear regression using altitude, mean annual runoff, and soil carbon density as predictors explained 40\% of the variability in lake {DOC}. While lake area and drainage ratio (catchment : lake area) were not correlated to lake {DOC} in the global data set, these two factors explained significant variation of the residuals of the multiple linear regression model in several regional subsets of data. These results suggest a hierarchical regulation of {DOC} in lakes, where climatic and topographic characteristics set the possible range of {DOC} concentrations of a certain region, and catchment and lake properties then regulate the {DOC} concentration in each individual lake.},

Here, we present continuous-field cover maps for tundra plant functional types ({PFTs}) across {\textasciitilde}125,000 km2 of Alaska’s North Slope at 30-m resolution. To develop maps, we collected a field-based training dataset using a point-intercept sampling method at 225 plots spanning bioclimatic and geomorphic gradients. We stratified vegetation by nine {PFTs} (e.g., low deciduous shrub, dwarf evergreen shrub, sedge, lichen) and summarized measurements of the {PFTs}, open water, bare ground and litter using the cover metrics total cover (areal cover including the understory) and top cover (uppermost canopy or ground cover). We then developed 73 spectral predictors derived from Landsat satellite observations (surface reflectance composites for {\textasciitilde}15-day periods from May–August) and five gridded environmental predictors (e.g., summer temperature, climatological snow-free date) to model cover of {PFTs} using the random forest data-mining algorithm. Model performance tended to be best for canopy-forming {PFTs}, particularly deciduous shrubs. Our assessment of predictor importance indicated that models for low-statured {PFTs} were improved through the use of seasonal composites from early and late in the growing season, particularly when similar {PFTs} were aggregated together (e.g., total deciduous shrub, herbaceous). Continuous-field maps have many advantages over traditional thematic maps, and the methods described here are well-suited to support periodic map updates in tandem with future field and Landsat observations.},

	abstract = {"Introduction: The remote village of Old Crow is Yukon's only community north of the Arctic Circle. The fascinating ice age history in this region has captured the imaginations of scientists, the Vuntut Gwitchin and the world for generations. Bluffs and banks along the Old Crow River are the richest source of ice age fossils in Canada. The Old Crow region also provides important clues about when the first people arrived in North America. In addition, layers of sediment and soil laid down over millions of years provide a crucial framework for the study of climate change in the Arctic. Scientific evidence from the Old Crow region provides many answers - and even more questions - about the long-vanished ice age world. ... An integral part of the story of ice age research in the Old Crow region is the continued involvement of the Vuntut Gwitchin. Since ancient times they have encountered the fossils of strange ancient beasts as they traversed the land and travelled the river. The importance of these ancient fossils is reflected in stories told by elders about how life as they know it came to be. Since the first arrival of scientists more than a century ago, the local people of Old Crow have provided valuable assistance and taken the time to share their stories and culture. With the signing of land claims and self-government agreements in 1993 the Vuntut Gwitchin gained greater responsibility for the management of ancient artifacts and fossils on their land. As a result, the Vuntut Gwitchin Government ({VGG}) owns and manages all fossils and artifacts found since 1995 on Vuntut Gwitchin Settlement Land. The creation of Vuntut National Park in 1995 further highlighted the importance of ice age research in the Old Crow region to the people of Canada."--{ASTIS} [online] database.},

Potential fluid pathways such as shear zones and faults are often associated with magnetite destructive alteration resulting in linear negative anomalies in magnetic data. Here, we present a new image analysis method that identifies geological structural complexity using lineaments automatically mapped within magnetic data. This quantitative analysis is efficient and self consistent in dealing with large volumes of data, and is suitable as a first-pass ground selection tool for orogenic gold exploration in greenfield terrains.},

	abstract = {Shorelines exhibit long-range dependence ({LRD}) and have been shown in some environments to be described in the wave number domain by a power-law characteristic of scale independence. Recent evidence suggests that the geomorphology of barrier islands can, however, exhibit scale dependence as a result of systematic variations in the underlying framework geology. The {LRD} of framework geology, which influences island geomorphology and its response to storms and sea level rise, has not been previously examined. Electromagnetic induction ({EMI}) surveys conducted along Padre Island National Seashore ({PAIS}), Texas, United States, reveal that the {EMI} apparent conductivity (σa) signal and, by inference, the framework geology exhibits {LRD} at scales of up to 101 to 102 km. Our study demonstrates the utility of describing {EMI} σa and lidar spatial series by a fractional autoregressive integrated moving average ({ARIMA}) process that specifically models {LRD}. This method offers a robust and compact way of quantifying the geological variations along a barrier island shoreline using three statistical parameters (p, d, q). We discuss how {ARIMA} models that use a single parameter d provide a quantitative measure for determining free and forced barrier island evolutionary behavior across different scales. Statistical analyses at regional, intermediate, and local scales suggest that the geologic framework within an area of paleo-channels exhibits a first-order control on dune height. The exchange of sediment amongst nearshore, beach, and dune in areas outside this region are scale independent, implying that barrier islands like {PAIS} exhibit a combination of free and forced behaviors that affect the response of the island to sea level rise.},

The northernmost lakes varied in their surface-water {CO}2 content from below to above saturation, but the southern lakes in this gradient had much higher surface concentrations that were well above airequilibrium. Surface-water {CH}4 concentrations were at least an order of magnitude above air-equilibrium values at all sites, and the diffusive fluxes of both gases increased from north to south. Methane oxidation in the surface waters from a northern lake was only 10\% of the emission rate, but at the southern end it was around 60\% of the efflux to the atmosphere, indicating that methanotrophy can play a substantive role in reducing net emissions. Overall, our observations show that lithalsa lakes can begin emitting {CH}4 and {CO}2 soon after they form, with effluxes of both gases that persist and increase as the permafrost continues to warm and erode.},

	abstract = {Over the next century, near-surface permafrost across the circumpolar Arctic is expected to degrade significantly, particularly for land areas south of 70°N. This is likely to cause widespread impacts on arctic hydrology, ecology, and trace gas emissions. Here, we present a review of recent studies investigating linkages between permafrost dynamics and river biogeochemistry in the Arctic, including consideration of likely impacts that warming-induced changes in permafrost may be having (or will have in the future) on the delivery of organic matter, inorganic nutrients, and major ions to the Arctic Ocean. These interacting processes can be highly complex and undoubtedly exhibit spatial and temporal variabilities associated with current permafrost conditions, sensitivity to permafrost thaw, mode of permafrost degradation (overall permafrost thaw, active layer deepening, and/or thermokarst processes), and environmental characteristics of watersheds (e.g. land cover, soil type, and topography). One of the most profound consequences of permafrost thaw projected for the future is that the arctic terrestrial freshwater system is likely to experience a transition from a surface water-dominated system to a groundwater-dominated system. Along with many other cascading impacts from this transition, mineral-rich groundwater may become an important contributor to streamflow, in addition to the currently dominant contribution from mineral-poor surface water. Most studies observe or predict an increase in major ion, phosphate, and silicate export with this shift towards greater groundwater contributions. However, we see conflicting accounts of whether the delivery of inorganic nitrogen and organic matter will increase or decrease with warming and permafrost thaw. It is important to note that uncertainties in the predictions of the total flux of biogeochemical constituents are tightly linked to future uncertainties in discharge of rivers. Nonetheless, it is clear that over the next century there will be important shifts in the river transport of organic matter, inorganic nutrients, and major ions, which may in turn have critical implications for primary production and carbon cycling on arctic shelves and in the Arctic Ocean basin interior.

	abstract = {The fate of carbon (C) contained within permafrost in boreal forest environments is an important consideration for the current and future carbon cycle as soils warm in northern latitudes. Currently, little is known about the microbiology or chemistry of permafrost soils that may affect its decomposition once soils thaw. We tested the hypothesis that low microbial abundances and activities in permafrost soils limit decomposition rates compared with active layer soils. We examined active layer and permafrost soils near Fairbanks, {AK}, the Yukon River, and the Arctic Circle. Soils were incubated in the lab under aerobic and anaerobic conditions. Gas fluxes at −5 and 5 °C were measured to calculate temperature response quotients (Q10). The Q10 was lower in permafrost soils (average 2.7) compared with active layer soils (average 7.5). Soil nutrients, leachable dissolved organic C ({DOC}) quality and quantity, and nuclear magnetic resonance spectroscopy of the soils revealed that the organic matter within permafrost soils is as labile, or even more so, than surface soils. Microbial abundances (fungi, bacteria, and subgroups: methanogens and Basidiomycetes) and exoenzyme activities involved in decomposition were lower in permafrost soils compared with active layer soils, which, together with the chemical data, supports the reduced Q10 values. {CH}4 fluxes were correlated with methanogen abundance and the highest {CH}4 production came from active layer soils. These results suggest that permafrost soils have high inherent decomposability, but low microbial abundances and activities reduce the temperature sensitivity of C fluxes. Despite these inherent limitations, however, respiration per unit soil C was higher in permafrost soils compared with active layer soils, suggesting that decomposition and heterotrophic respiration may contribute to a positive feedback to warming of this eco region.},

	abstract = {This synthesis addresses the vulnerability of the North American high-latitude soil organic carbon ({SOC}) pool to climate change. Disturbances caused by climate warming in arctic, subarctic, and boreal environments can result in significant redistribution of C among major reservoirs with potential global impacts. We divide the current northern high-latitude {SOC} pools into (1) near-surface soils where {SOC} is affected by seasonal freeze-thaw processes and changes in moisture status, and (2) deeper permafrost and peatland strata down to several tens of meters depth where {SOC} is usually not affected by short-term changes. We address key factors (permafrost, vegetation, hydrology, paleoenvironmental history) and processes (C input, storage, decomposition, and output) responsible for the formation of the large high-latitude {SOC} pool in North America and highlight how climate-related disturbances could alter this pool's character and size. Press disturbances of relatively slow but persistent nature such as top-down thawing of permafrost, and changes in hydrology, microbiological communities, pedological processes, and vegetation types, as well as pulse disturbances of relatively rapid and local nature such as wildfires and thermokarst, could substantially impact {SOC} stocks. Ongoing climate warming in the North American high-latitude region could result in crossing environmental thresholds, thereby accelerating press disturbances and increasingly triggering pulse disturbances and eventually affecting the C source/sink net character of northern high-latitude soils. Finally, we assess postdisturbance feedbacks, models, and predictions for the northern high-latitude {SOC} pool, and discuss data and research gaps to be addressed by future research.},

The present study was undertaken to assess greenhouse gas stocks and fluxes in eight lithalsa lakes across a 200 km gradient of permafrost degradation in subarctic Québec. The northernmost lakes varied in their surface-water {CO}2 content from below to above saturation, but the southern lakes in this gradient had much higher surface concentrations that were well above airequilibrium. Surface-water {CH}4 concentrations were at least an order of magnitude above air-equilibrium values at all sites, and the diffusive fluxes of both gases increased from north to south. Methane oxidation in the surface waters from a northern lake was only 10\% of the emission rate, but at the southern end it was around 60\% of the efflux to the atmosphere, indicating that methanotrophy can play a substantive role in reducing net emissions. Overall, our observations show that lithalsa lakes can begin emitting {CH}4 and {CO}2 soon after they form, with effluxes of both gases that persist and increase as the permafrost continues to warm and erode.},

	abstract = {The permafrost monitoring network in the polar regions of the Northern Hemisphere was enhanced during the International Polar Year ({IPY}), and new information on permafrost thermal state was collected for regions where there was little available. This augmented monitoring network is an important legacy of the {IPY}, as is the updated baseline of current permafrost conditions against which future changes may be measured. Within the Northern Hemisphere polar region, ground temperatures are currently being measured in about 575 boreholes in North America, the Nordic region and Russia. These show that in the discontinuous permafrost zone, permafrost temperatures fall within a narrow range, with the mean annual ground temperature ({MAGT}) at most sites being higher than À28C. A greater range in {MAGT} is present within the continuous permafrost zone, from above À18C at some locations to as low as À158C. The latest results indicate that the permafrost warming which started two to three decades ago has generally continued into the {IPY} period. Warming rates are much smaller for permafrost already at temperatures close to 08C compared with colder permafrost, especially for ice-rich permafrost where latent heat effects dominate the ground thermal regime. Colder permafrost sites are warming more rapidly. This improved knowledge about the permafrost thermal state and its dynamics is important for multidisciplinary polar research, but also for many of the 4 million people living in the Arctic. In particular, this knowledge is required for designing effective adaptation strategies for the local communities under warmer climatic conditions. Copyright \# 2010 John Wiley \& Sons, Ltd.},

This is equivalent to 5.7 ± 4.0\% of total anthropogenic emissions for the Intergovernmental Panel on Climate Change ({IPCC}) representative concentration pathway ({RCP}) 8.5 scenario and would increase global temperatures by 0.29 ± 0.21 °C or 7.8 ± 5.7\%. For {RCP}4.5, the scenario closest to the 2 °C warming target for the climate change treaty, the range of cumulative emissions in 2100 from thawing permafrost decreases to between 27 and 100 Gt C with temperature increases between 0.05 and 0.15 °C, but the relative fraction of permafrost to total emissions increases to between 3\% and 11\%. Any substantial warming results in a committed, long-term carbon release from thawing permafrost with 60\% of emissions occurring after 2100, indicating that not accounting for permafrost emissions risks overshooting the 2 °C warming target. Climate projections in the {IPCC} Fifth Assessment Report ({AR}5), and any emissions targets based on those projections, do not adequately account for emissions from thawing permafrost and the effects of the {PCF} on global climate. We recommend the {IPCC} commission a special assessment focusing on the {PCF} and its impact on global climate to supplement the {AR}5 in support of treaty negotiation.},

	abstract = {Permafrost thaw in peatlands has the potential to alter catchment export of dissolved organic carbon ({DOC}) and thus influence downstream aquatic C cycling. Subarctic peatlands are often mosaics of different peatland types, where permafrost conditions regulate the hydrological setting of each type. We show that hydrological setting is key to observed differences in magnitude, timing, and chemical composition of {DOC} export between permafrost and nonpermafrost peatland types, and that these differences influence the export of {DOC} of larger catchments even when peatlands are minor catchment components. In many aspects, {DOC} export from a studied peatland permafrost plateau was similar to that of a forested upland catchment. Similarities included low annual export (2–3 g C {mÀ}2) dominated by the snow melt period ({\textasciitilde}70\%), and how substantial {DOC} export following storms required wet antecedent conditions. Conversely, nonpermafrost fens had higher {DOC} export (7 g C {mÀ}2), resulting from sustained hydrological connectivity during summer. Chemical composition of catchment {DOC} export arose from the mixing of highly aromatic {DOC} from organic soils from permafrost plateau soil water and upland forest surface horizons with nonaromatic {DOC} from mineral soil groundwater, but was further modulated by fens. Increasing aromaticity from fen inflow to outlet was substantial and depended on both water residence time and water temperature. The role of fens as catchment biogeochemical hotspots was further emphasized by their capacity for sulfate retention. As a result of fen characteristics, a 4\% fen cover in a mixed catchment was responsible for 34\% higher {DOC} export, 50\% higher {DOC} concentrations and {\textasciitilde}10\% higher {DOC} aromaticity at the catchment outlet during summer compared to a nonpeatland upland catchment. Expansion of fens due to thaw thus has potential to influence landscape C cycling by increasing fen capacity to act as biogeochemical hotspots, amplifying aquatic C cycling, and increasing catchment {DOC} export.},

	abstract = {In the sporadic permafrost zone of northwestern Canada, boreal forest carbon dioxide ({CO}2) fluxes will be altered directly by climate change through changing meteorological forcing and indirectly through changes in landscape functioning associated with thaw-induced collapse-scar bog (‘wetland’) expansion. However, their combined effect on landscape-scale net ecosystem {CO}2 exchange ({NEELAND}), resulting from changing gross primary productivity ({GPP}) and ecosystem respiration ({ER}), remains unknown. Here, we quantify indirect land cover change impacts on {NEELAND} and direct climate change impacts on modeled temperature- and light-limited {NEELAND} of a boreal forest–wetland landscape. Using nested eddy covariance flux towers, we find both {GPP} and {ER} to be larger at the landscape compared to the wetland level. However, annual {NEELAND} (À20 g C {mÀ}2) and wetland {NEE} (À24 g C {mÀ}2) were similar, suggesting negligible wetland expansion effects on {NEELAND}. In contrast, we find non-negligible direct climate change impacts when modeling {NEELAND} using projected air temperature and incoming shortwave radiation. At the end of the 21st century, modeled {GPP} mainly increases in spring and fall due to reduced temperature limitation, but becomes more frequently light-limited in fall. In a warmer climate, {ER} increases year-round in the absence of moisture stress resulting in net {CO}2 uptake increases in the shoulder seasons and decreases during the summer. Annually, landscape net {CO}2 uptake is projected to decline by 25 Æ 14 g C {mÀ}2 for a moderate and 103 Æ 38 g C {mÀ}2 for a high warming scenario, potentially reversing recently observed positive net {CO}2 uptake trends across the boreal biome. Thus, even without moisture stress, net {CO}2 uptake of boreal forest–wetland landscapes may decline, and ultimately, these landscapes may turn into net {CO}2 sources under continued anthropogenic {CO}2 emissions. We conclude that {NEELAND} changes are more likely to be driven by direct climate change rather than by indirect land cover change impacts.},

This study investigates hydrological carbon transport through the subsurface to streams and how it is affected by the distribution of subsurface hydrological pathways and travel times through the landscape. We develop a consistent mechanistic, pathway- and travel time-based modeling approach for release and transport of dissolved organic carbon ({DOC}) and dissolved inorganic carbon ({DIC}). The model implications are tested against observations in the subarctic Abiskojokken catchment in northernmost Sweden (68◦21 N, 18◦49 E) as a field case example of a discontinuous permafrost region. The results show: (a) For {DOC}, both concentration and load are essentially flow-independent because their dynamics are instead dominated by the annual renewal and depletion. Specifically, the flow independence is the result of the small characteristic {DOC} respiration-dissolution time scale, in the range of 1 yr, relative to the average travel time of water through the subsurface to the stream. (b) For {DIC}, the load is highly flow-dependent due to the large characteristic weatheringdissolution time, much larger than 1 yr, relative to the average subsurface water travel time to the stream. This rate relation keeps the {DIC} concentration essentially flow-independent, and thereby less fluctuating in time than the {DIC} load.},

	abstract = {Permafrost peatlands store one-third of the total carbon (C) in the atmosphere and are increasingly vulnerable to thaw as high-latitude temperatures warm. Large uncertainties remain about C dynamics following permafrost thaw in boreal peatlands. We used a chronosequence approach to measure C stocks in forested permafrost plateaus (forest) and thawed permafrost bogs, ranging in thaw age from young ({\textless}10 years) to old ({\textgreater}100 years) from two interior Alaska chronosequences. Permafrost originally aggraded simultaneously with peat accumulation (syngenetic permafrost) at both sites. We found that upon thaw, C loss of the forest peat C is equivalent to {\textasciitilde}30\% of the initial forest C stock and is directly proportional to the prethaw C stocks. Our model results indicate that permafrost thaw turned these peatlands into net C sources to the atmosphere for a decade following thaw, after which post-thaw bog peat accumulation returned sites to net C sinks. It can take multiple centuries to millennia for a site to recover its prethaw C stocks; the amount of time needed for them to regain their prethaw C stocks is governed by the amount of C that accumulated prior to thaw. Consequently, these findings show that older peatlands will take longer to recover prethaw C stocks, whereas younger peatlands will exceed prethaw stocks in a matter of centuries. We conclude that the loss of sporadic and discontinuous permafrost by 2100 could result in a loss of up to 24 Pg of deep C from permafrost peatlands.},

The model incorporates the influence of active layer dynamics and slope aspect on hydrological flowpaths and resulting {DOC} mobilization. Calibration and evaluation of the model was undertaken using observations from Granger Basin within the Wolf Creek research basin, Yukon, northern Canada. Results show that the model was able to capture the dominant hydrological response and {DOC} dynamics of the catchment reasonably well. Simulated {DOC} was highly correlated with observed {DOC} (r2 = 0.65) for the study period. During the snowmelt period, the model adequately captured the observed dynamics, with simulations generally reflecting the timing and magnitude of the observed {DOC} and stream discharge. The model was less successful over the later summer period although this partly reflected a lack of {DOC} observations for calibration. The developed model offers a valuable framework for investigating the interactions between hydrological and {DOC} processes in these highly dynamic systems, where data acquisition is often very difficult. © 2015 The Authors Hydrological Processes Published by John Wiley \& Sons, Ltd.},

We measured dissolved organic carbon ({DOC}) concentration, dissolved organic matter ({DOM}) absorption and fluorescence, and stable isotopes of {DOM}, {DOM} precursor materials, and bacteria to elucidate the importance of river water, macrophytes, and thermokarst as {DOM} sources to Mackenzie Delta lakes. Despite standing stocks of macrophyte C that are sevenfold to 12-fold greater than those of total {DOC}, stable isotopes indicated that autochthonous sources contributed less than 15\% to overall {DOM} in macrophyte-rich lakes. Instead, fluorescence and absorption indicated that the moderate summertime increase in {DOC} concentration in macrophyte-rich lakes was the result of infrequent flushing, while bacterial d13C indicated rapid bacterial removal of autochthonous {DOC} from the water column. In thermokarst lakes, summertime increases in {DOC} concentration were substantial, and stable isotopes indicated that much of this increase came from C released as a result of thermokarst-related processes. Our results indicate that these distinct sources of {DOM} to neighboring arctic Delta lakes may drive between-lake differences in C cycling and energy flow. Rapidly assimilated macrophyte {DOM} should be an important contributor to microbial food webs in our study lakes. In contrast, the accumulation of thermokarst-origin {DOM} allows for a significant role in physico-chemistry but indicates a lesser contribution of this {DOM} to higher trophic levels.},

	abstract = {Rapidly rising temperatures in the Arctic might cause a greater release of greenhouse gases ({GHGs}) to the atmosphere. To study the effect of warming on {GHG} dynamics, we deployed open-top chambers in a subarctic tundra site in Northeast European Russia. We determined carbon dioxide ({CO}2), methane ({CH}4), and nitrous oxide (N2O) fluxes as well as the concentration of those gases, inorganic nitrogen (N) and dissolved organic carbon ({DOC}) along the soil profile. Studied tundra surfaces ranged from mineral to organic soils and from vegetated to unvegetated areas. As a result of air warming, the seasonal {GHG} budget of the vegetated tundra surfaces shifted from a {GHG} sink of À300 to À198 g {CO}2–eq {mÀ}2 to a source of 105 to 144 g {CO}2–eq {mÀ}2. At bare peat surfaces, we observed increased release of all three {GHGs}. While the positive warming response was dominated by {CO}2, we provide here the first in situ evidence of increasing N2O emissions from tundra soils with warming. Warming promoted N2O release not only from bare peat, previously identified as a strong N2O source, but also from the abundant, vegetated peat surfaces that do not emit N2O under present climate. At these surfaces, elevated temperatures had an adverse effect on plant growth, resulting in lower plant N uptake and, consequently, better N availability for soil microbes. Although the warming was limited to the soil surface and did not alter thaw depth, it increased concentrations of {DOC}, {CO}2, and {CH}4 in the soil down to the permafrost table. This can be attributed to downward {DOC} leaching, fueling microbial activity at depth. Taken together, our results emphasize the tight linkages between plant and soil processes, and different soil layers, which need to be taken into account when predicting the climate change feedback of the Arctic.},

The modeling approach which included quantitative assessment of associated uncertainties was conditioned by geochemical tracers which discriminate dominant water sources. Integration of {DOC} was predicated on statistical time series models which identified air temperature and streamflow as the key proxies that capture {DOC} supply and transport processes in two upland catchments in Scotland, {UK}. Conceptualizing the nonlinear partitioning of quick near-surface and slower groundwater runoff sources in combination with a {DOC} mass balance resulted in a coupled, low-parameter mechanistic model. Model tests showed mostly sensitive parameters and reasonable simulation results with seasonally controlled {DOC} supply and event-based {DOC} transport. Transport is facilitated even for smaller events by overland flow from saturated histosols connected to the stream network. However, during prolonged dry periods, near-surface runoff “switches off” and stream {DOC} is dominated by low concentration groundwaters. Furthermore, the model was able to explain subtle differences in {DOC} dynamics between the two catchments mainly reflecting the distribution of saturated soils and available storage. We conclude that tracers and statistical time series models can successfully guide the development of parsimonious yet structurally consistent water quality models. Parsimonious models provide tools for estimating {DOC} dynamics and loads with reduced uncertainty and potentially greater transferability.},

	abstract = {Climate change is causing extensive warming across Arctic regions resulting in permafrost degradation, alterations to regional hydrology and shifting amounts and composition of dissolved organic matter ({DOM}) transported by streams and rivers. Here, we characterize the {DOM} composition and optical properties of the six largest Arctic rivers draining into the Arctic Ocean to examine the ability of optical measurements to provide meaningful insights into terrigenous carbon export patterns and biogeochemical cycling. The chemical composition of aquatic {DOM} varied with season, spring months were typified by highest lignin phenol and dissolved organic carbon ({DOC}) concentrations with greater hydrophobic acid content, and lower proportions of hydrophilic compounds, relative to summer and winter months. Chromophoric {DOM} ({CDOM}) spectral slope (S275–295) tracked seasonal shifts in {DOM} composition across river basins. Fluorescence and parallel factor analysis identified seven components across the six Arctic rivers. The ratios of “terrestrial humic-like” vs. “marine humic-like” fluorescent components co-varied with lignin monomer ratios over summer and winter months, suggesting fluorescence may provide information on the age and degradation state of riverine {DOM}. {CDOM} absorbance (a350) proved a sensitive proxy for lignin phenol concentrations across all six river basins and over the hydrograph, enabling for the first time the development of a single pan-arctic relationship between a350 and terrigenous {DOC} (R2 = 0.93). Combining this lignin proxy with high-resolution monitoring of a350, pan-arctic estimates of annual lignin flux were calculated to range from 156 to 185 Gg, resulting in shorter and more constrained estimates of terrigenous {DOM} residence times in the Arctic Ocean (spanning 7 months to 2½ years). Furthermore, multiple linear regression models incorporating both absorbance and fluorescence variables proved capable of explaining much of the variability in lignin composition across rivers and seasons. Our findings suggest that synoptic, high-resolution optical measurements can provide improved understanding of northern high-latitude organic matter cycling and flux, and prove an important technique for capturing future climate-driven changes.},

	abstract = {As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of the critical factors driving carbon balance are unlikely in the near future, so to address this gap, we present estimates from 98 permafrost-region experts of the response of biomass, wildfire, and hydrologic carbon flux to climate change. Results suggest that contrary to model projections, total permafrost-region biomass could decrease due to water stress and disturbance, factors that are not adequately incorporated in current models. Assessments indicate that end-of-the-century organic carbon release from Arctic rivers and collapsing coastlines could increase by 75\% while carbon loss via burning could increase four-fold. Experts identified water balance, shifts in vegetation community, and permafrost degradation as the key sources of uncertainty in predicting future system response. In combination with previous findings, results suggest the permafrost region will become a carbon source to the atmosphere by 2100 regardless of warming scenario but that 65\%–85\% of permafrost carbon release can still be avoided if human emissions are actively reduced.},

A versatile and easy to use monitoring system will allow researchers and growers to improve the follow-up management strategies within farms once potential problems have been detected. This study reviewed existing remote sensing platforms and relevant information applied to crops and specifically grapevines to equip a simple Unmanned Aerial Vehicle ({UAV}) using a visible high definition {RGB} camera. The objective of the proposed Unmanned Aerial System ({UAS}) was to implement a Digital Surface Model ({DSM}) in order to obtain accurate information about the affected or missing grapevines that can be attributed to potential biotic or abiotic stress effects. The analysis process started with a three-dimensional (3D) reconstruction from the {RGB} images collected from grapevines using the {UAS} and the Structure from Motion ({SfM}) technique to obtain the {DSM} applied on a per-plant basis. Then, the {DSM} was expressed as greyscale images according to the halftone technique to finally extract the information of affected and missing grapevines using computer vision algorithms based on canopy cover measurement and classification. To validate the automated method proposed, each grapevine row was visually inspected within the study area. The inspection was then compared to the digital assessment using the proposed {UAS} in order to validate calculations of affected and missing grapevines for the whole studied vineyard. Results showed that the percentage of affected and missing grapevines was 9.5\% and 7.3\%, respectively from the area studied. Therefore, for this specific study, the abiotic stress that affected the experimental vineyard (frost) impacted a total of 16.8 \% of plants. This study provided a new method for automatically surveying affected or missing grapevines in the field and an evaluation tool for plant growth conditions, which can be implemented for other uses such as canopy management, irrigation scheduling and other precision agricultural applications.},

The present study suggests a methodology to investigate the relationships between high-resolution multispectral images (0.05 m/pixel) acquired using an Unmanned Aerial Vehicle ({UAV}), and {GLSD} foliar symptoms monitored by ground surveys. This approach showed high correlation between Normalized Differential Vegetation Index ({NDVI}) acquired by the {UAV} and {GLSD} symptoms, and discrimination between symptomatic from asymptomatic plants. High-resolution multispectral images were acquired during June and July of 2012 and 2013, in an experimental vineyard heavily affected by {GLSD}, located in Tuscany (Italy), where vines had been surveyed and mapped since 2003. Each vine was located with a global positioning system, and classified for appearance of foliar symptoms and disease severity at weekly intervals from the beginning of each season. Remote sensing and ground observation data were analyzed to promptly identify the early stages of disease, even before visual detection. This work suggests an innovative methodology for quantitative and qualitative analysis of spatial distribution of symptomatic plants. The system may also be used for exploring the physiological bases of {GLSD}, and predicting the onset of this disease.},

Its practical implementation is dependant on various technological developments: crop sensors and yield monitors, local and remote sensors, Global Positioning Systems ({GPS}), {VRA} (Variable-Rate Application) equipment and machinery, Geographic Information Systems ({GIS}) and systems for data analysis and interpretation. This paper reviews a number of research lines related to {PV}. These areas of research have focused on four very specific fields: 1) quantification and evaluation of within-field variability, 2) delineation of zones of differential treatment at parcel level, based on the analysis and interpretation of this variability, 3) development of Variable-Rate Technologies ({VRT}) and, finally, 4) evaluation of the opportunities for site-specific vineyard management. Research in these fields should allow winegrowers and enologists to know and understand why yield variability exists within the same parcel, what the causes of this variability are, how the yield and its quality are interrelated and, if spatial variability exists, whether site-specific vineyard management is justifiable on a technical and economic basis.},

	abstract = {Spatial variability in various indices of winegrape quality was studied over several vintages in blocks planted to Cabernet Sauvignon and Ruby Cabernet in the Coonawarra (1999–2002) and Sunraysia (2000–2002) regions of Australia. At both sites, inter-annual variation was marked whilst intra-annual variation was much greater for some indices (e.g. concentration of total phenolics) than others (e.g. Baumé). The magnitude of intra-annual variation was readily identified in terms of the ‘spread’, defined as the difference between the maximum and minimum values, expressed as a \% of the median value. Typical values of the spread were 20\% for Baumé, but could be as high as 117\% for phenolics, and better indicated the extent of variation facing the winemaker than the coefficient of variation ({CV}; typically 3\% for Baumé and 14\% for phenolics). For all attributes, variation in any given year showed marked spatial structure, with the patterns of variation being broadly consistent for each attribute in each year of the study, and with many attributes following similar patterns. The results therefore strongly support the idea of zonal vineyard management. However, fruit quality zone identification is dependent on a large sampling effort. Therefore, given the current availability of yield monitors, the finding that between-zone differences in quality indices were generally significant (P {\textless} 0.05) for zones identified on the basis of yield alone, and, in the absence of an on-the-go sensing capability, it is suggested that zonal management should proceed on the basis of zones of characteristic yield productivity. Based on the present work, it is suggested that development of an on-the-go fruit quality sensing technology would enable the wine industry to maximise its opportunity to gain benefit from differential vineyard management such as selective harvesting. Indeed, the results of this work suggest that in the absence of zonal management, preferably supported by on-the-go quality sensing, winemaker demands for delivery of uniform parcels of fruit are unlikely to be satisfied.},

It is based on assessing field spatial variability and implementing site-specific management strategies, which can require georeferenced information of the three dimensional (3D) grapevine canopy structure as one of the input data. The 3D structure of vineyard fields can be generated applying photogrammetric techniques to aerial images collected with Unmanned Aerial Vehicles ({UAVs}), although processing the large amount of crop data embedded in 3D models is currently a bottleneck of this technology. To solve this limitation, a novel and robust object-based image analysis ({OBIA}) procedure based on Digital Surface Model ({DSM}) was developed for 3D grapevine characterization. The significance of this work relies on the developed {OBIA} algorithm which is fully automatic and self-adaptive to different crop-field conditions, classifying grapevines, and row gap (missing vine plants), and computing vine dimensions without any user intervention. The results obtained in three testing fields on two different dates showed high accuracy in the classification of grapevine area and row gaps, as well as minor errors in the estimates of grapevine height. In addition, this algorithm computed the position, projected area, and volume of every grapevine in the field, which increases the potential of this {UAV}- and {OBIA}-based technology as a tool for site-specific crop management applications.},

	abstract = {Many northern lake-rich regions are undergoing pronounced hydrological change, yet inadequate knowledge of the drivers of these landscape-scale responses hampers our ability to predict future conditions. We address this challenge in the thermokarst landscape of Old Crow Flats ({OCF}) using a combination of remote sensing imagery and monitoring of stable isotope compositions of lake waters over three thaw seasons (2007–2009). Quantitative analysis confirmed that the hydrological behavior of lakes is strongly influenced by catchment vegetation and physiography. Catchments of snowmelt-dominated lakes, typically located in southern peripheral areas of {OCF}, encompass high proportions of woodland/forest and tall shrub vegetation (mean percent land cover = ca. 60\%). These land cover types effectively capture snow and generate abundant snowmelt runoff that offsets lake water evaporation. Rainfalldominated lakes that are not strongly influenced by evaporation are typically located in eastern and northern {OCF} where their catchments have higher proportions of dwarf shrub/herbaceous and sparse vegetation (ca. 45\%), as well as surface water (ca. 20\%). Evaporation-dominated lakes, are located in the {OCF} interior where their catchments are distinguished by substantially higher lake area to catchment area ratios ({LA}/{CA} = ca. 29\%) compared to low evaporation-influenced rainfall-dominated (ca. 10\%) and snowmelt-dominated (ca. 4\%) lakes. Lakes whose catchments contain {\textgreater}75\% combined dwarf shrub/herbaceous vegetation and surface water are most susceptible to evaporative lake-level drawdown, especially following periods of low precipitation. Findings indicate that multiple hydrological trajectories are probable in response to climate-driven changes in precipitation amount and seasonality, vegetation composition, and thermokarst processes. These will likely include a shift to greater snowmelt influence in catchments experiencing expansion of tall shrubs, greater influence from evaporation in catchments having higher proportions of surface water, and an increase in the rate of thermokarst lake expansion and probability of drainage. Local observations suggest that some of these changes are already underway.},

	abstract = {Tools that can monitor biomass and nutritional quality of forage plants are needed to understand how arctic herbivores may respond to the rapidly changing environment at high latitudes. The Normalized Difference Vegetation Index ({NDVI}) has been widely used to assess changes in abundance and distribution of terrestrial vegetative communities. However, the efficacy of {NDVI} to measure seasonal changes in biomass and nutritional quality of forage plants in the Arctic remains largely un-evaluated at landscape and fine-scale levels. We modeled the relationships between {NDVI} and seasonal changes in aboveground biomass and nitrogen concentration in halophytic graminoids, a key food source for arctic-nesting geese. The model was calibrated based on data collected at one site and validated using data from another site. Effects of spatial scale on model accuracy were determined by comparing model predictions between {NDVI} derived from moderate resolution (250 × 250 m pixels) satellite data and high resolution (20 cm diameter area) handheld spectrometer data. {NDVI} derived from the handheld spectrometer was a superior estimator (R2 ≥ 0.67) of seasonal changes in aboveground biomass compared to satellite-derived {NDVI} (R2 ≤ 0.40). The addition of temperature and precipitation variables to the model for biomass improved fit, but provided minor gains in predictive power beyond that of the {NDVI}-only model. This model, however, was only a moderately accurate estimator of biomass in an ecologically-similar halophytic graminoid wetland located 100 km away, indicating the necessity for site-specific validation. In contrast to assessments of biomass, satellite-derived {NDVI} was a better estimator for the timing of peak percent of nitrogen than {NDVI} derived from the handheld spectrometer. We confirmed that the date when {NDVI} reached 50\% of its seasonal maximum was a reasonable approximation of the period of peak spring vegetative green-up and peak percent nitrogen. This study demonstrates the importance of matching the scale of {NDVI} measurements to the vegetation properties of biomass and nitrogen phenology.},

	title = {Assessment of land cover change using remote sensing, aerial photographs and dendrochronological approaches in Old Crow Flats, Yukon},
	abstract = {Changing climate conditions have been amplified across Arctic and subarctic regions, which have influenced landscape characteristics. Notably, shrub vegetation size and spatial distributions have increased in many locations, which have been found to influence other landscape components including hydrological and ecological conditions. The 14,500 km2 Old Crow Flats ({OCF}) basin in northern Yukon is one such landscape where past research has identified relations among land cover and hydroecological conditions, however, more refined insight of land cover changes is required to identify how this important and vast wetland will respond to future changing climate. Here, we evaluated spatial and temporal patterns of vegetation change in {OCF} since 1985 using Landsat imagery and ground control observations from plot sampling, oblique aerial images, and an unmanned aerial vehicle ({UAV}). Trends in greening vegetation spatial distribution were identified using remote-sensing indicators, the normalized difference vegetation index ({NDVI}) and tasseled cap transformation ({TCg}). Findings showed a significant increase in vegetation greening during the last 30 years, which was compared with a Landsat-derived land cover classification layer. Quantitative analysis showed that greening occurred mostly in 8,335 km2 shrub-vegetation classified areas (outside of drained lake basins) from 1985 to 2014. Shrub vegetation coverage was estimated to increase approximately 13.25 km2 per year in {OCF}. The greatest increases in vegetation was found across the northern and eastern ecotone areas of the {OCF} basin. The highest percentage of greening ({\textasciitilde}7.58\%) was observed in the northern {OCF} basin and northern parts of the Black Fox Creek subcatchment, and the highest coverage of greening ({\textasciitilde}2,108 km2) was found in the Johnson Creek subcatchment. Additional validation of remote sensing analysis was generated from 550 oblique photographs, as well as integration of shrub age analysis and acquisition of multispectral images in two 90-m plots. Oblique photographs showed the majority (72\%) of sampled pixels with significant greening were shrub vegetation. {UAV} and analysis of tree rings in the two plots within greening pixels showed that shrub was the dominant vegetation (70-73\% coverage) and that 70\% of shrubs sampled were dated at ≤ 30 years old. The Landsat-derived vegetation greening products will be essential for refining our knowledge of how changing land cover is impacting lake and river hydroecological conditions. Insight generated here about key wildlife habitat will be useful for stakeholders including the Vuntut Gwitchin First Nation and Vuntut National Park as they form monitoring and land management plans as climate continues to change.},

	abstract = {Recent northern vegetation changes caused by climate warming have been well documented, using experimental plot warming to examine vegetation-specific changes and satellite image data to examine overall trends. Previous remote sensing efforts have employed the Normalized Difference Vegetation Index ({NDVI}) from {AVHRR}, whose 1 km to 8 km pixel size is too large for examination of broad scale vegetation-specific responses because of mixing within the pixel footprint. In this paper, we reconcile differences between field- and remote sensing-based approaches by using both medium-resolution (30 m) and coarseresolution (1 km) data to study 20 years of vegetation-specific responses to northern climate warming (1986 to 2006). Trends are compared among vegetation communities from two separate Landsat classifications in Canada’s eastern and western forest-tundra transition zone, as well as a 1 km {AVHRR} database recently developed over Canada. A comparison of absolute trends among mapped vegetation communities revealed lichen-dominated communities consistently exhibiting lower trends than those dominated by vascular plants, with both exhibiting increasing {NDVI}. Our results and those obtained from experimental warming suggest that the magnitude difference in {NDVI} increase between lichen and vascular vegetation is related to increasing vigor and biomass of vascular vegetation, in contrast to physiological impairment of lichen due to the short-term secondary effect of temperature on moisture. In the longer term, succession from lichen to vascular is likely responsible for the small observed {NDVI} increase over lichen-dominated regions. The fact that both Landsat and {AVHRR} exhibited similar relative vegetation-specific trends in {NDVI} suggests that this phenomenon may be widespread in the North.},

Especially the stem-cycle approach requires complex algorithms to disentangle cyclic phases. Here, we present an R package, named {dendrometeR}, that facilitates the analysis of dendrometer data using both analytical methods. By making the package freely available, we make a first step towards comparable and reproducible methods to analyze dendrometer data. The package contains customizable functions to prepare, verify, process and plot dendrometer series, as well as functions that facilitate the analysis of dendrometer data (i.e. daily statistics or extracted phases) in relation to environmental data.

In this paper, we analyze the spatiotemporal variations in the terrestrial water storage ({TWS}) of the {ACTR} and three of the largest pan-Arctic river basins (Lena, Mackenzie, Yukon). To do this, we utilize monthly Gravity Recovery and Climate Experiment ({GRACE}) data from 2002 to 2016. Together with global land reanalysis, and river runoff data, we identify declining {TWS} trends throughout the {ACTR} that we attribute largely to increasing evapotranspiration driven by increasing summer air temperatures. In terms of regional changes, large and significant negative trends in {TWS} are observed mainly over the North American continent. At basin scale, we show that, in the Lena River basin, the autumnal {TWS} signal persists until the spring of the following year, while in the Mackenzie River basin, the {TWS} level in the autumn and winter has no significant impact on the following year. As expected global warming is expected to be particularly significant in the northern regions, our results are important for understanding future {TWS} trends, with possible further decline.},

In this paper, Landsat 8 {OLI} image was used with Support Vector Machine ({SVM}) and Tasseled Cap Transformation ({TCT}) for land cover classification. Firstly, the Top of Atmospheric ({TOA}) reflectance based {TCT} was developed based on Landsat 8 {OLI} images.

The present results showed that compared with using the original 8 Landsat 8 {OLI} bands, the classification results from {ISODATA} and K-Means based on both of {TCT} Greenness and Wetness had better robustness and accuracy, and the classification using {SVM} with {TCT} had better efficiency and accuracy.},

This article describes the atmospheric correction that we have implemented for the campaign. We first present the theoretical basis of our approach, which is grounded in the {ATmospheric} {REMoval} ({ATREM}) algorithm. We then describe new enhancements including retrieval of pressure altitude, which improves accuracy over widely varying topography, and joint retrieval of optical absorption for three phases of water (vapor, liquid, and ice), which improves accuracy over vegetated areas. Reflectance is validated using ground spectra acquired across a wide range of targets and elevations.

Therefore the three-dimensional (3D) ordinary kriging technique cannot be directly used to map the distribution of {SOC} at a regional scale. The objectives of this study were to map the 3D distribution of {SOC} at a regional scale by combining kriging method with the profile depth function of {SOC} ({KPDF}), and to explore the effects of soil texture and land use type on vertical distribution of {SOC} in a fluvial plain. A total of 605 samples were collected from 121 soil profiles (0.0 to 1.0 m, 0.20 m increment) in Quzhou County, China and {SOC} contents were determined for each soil sample. The {KPDF} method was used to obtain the 3D map of {SOC} at the county scale. The results showed that the exponential equation well described the vertical distribution of mean values of the {SOC} contents. The coefficients of determination, root mean squared error and mean prediction error between the measured and the predicted {SOC} contents were 0.52, 1.82 and -0.24 g kg-1 respectively, suggesting that the {KPDF} method could be used to produce a 3D map of {SOC} content. The surface {SOC} contents were high in the mid-west and south regions, and low values lay in the southeast corner. The {SOC} contents showed significant positive correlations between the five different depths and the correlations of {SOC} contents were larger in adjacent layers than in non-adjacent layers. Soil texture and land use type had significant effects on the spatial distribution of {SOC}. The influence of land use type was more important than that of soil texture in the surface soil, and soil texture played a more important role in influencing the {SOC} levels for 0.2-0.4 m layer.},

The method has been used to evaluate evaporation and water balance at two contrasting sites in northern Canada. Areally weighted evaporative discharge from an 850 km2 tundra catchment in south-central District of Keewatin is estimated to be about 7 \% of total water discharge (≈ 16 mm/yr), compared to about 19 \% (≈ 65 mm/yr) from a 300 km2 forested watershed in the Upper Mackenzie Valley. Lakes in both watersheds exhibit broad ranges of evaporation/inflow ratios related to local water balance. The potential errors in the estimates are evaluated through consideration of possible variations in basin storage, humidity, and the isotopic composition of atmospheric vapour.},

Recent changes in arctic climate, including increasing surface air temperature, declining sea ice extent, and shifts in the amounts seasonality of precipitation are linked to the strong positive phase of the {AO}/{NAO}. Here, we show that phase changes in the {AO}/{NAO} are recorded in the isotopic (d18O and D-carbon isotope discrimination) characteristics of the long-lived circum-arctic plant, Cassiope tetragona, as summer rain has become a more important water source than snowmelt water which in turn has lead to decreases in D and reductions in plant stem growth. These isotopic records in C. tetragona may facilitate reconstructions of climate, plant–soil water relations, plant gas exchange attributes and a mechanistic understanding of growth responses to shifts in atmospheric circulation. If plant specimens were available for populations across the arctic as part of the International Polar Year, these archives could provide a circum-arctic record of historical climate change and associated shifts in physiological plant performance and growth.},

The most pronounced changes were observed during the second half of the 20th century, and differed between stands. Three sites kept a constant ci/ca ratio, leading to significant ci and {iWUE} increases (active response to ca); whereas a significant increase in ci/ca resulted in the lowest {iWUE} increase of all stands at a relict Pinus uncinata forest site (passive response to ca). A significant decrease in ci/ca led to the greatest {iWUE} improvement at the northwestern site. We tested the climatic signal strength registered in the d13C series after removing the low-frequency trends due to the physiological responses to increasing ca. We found stronger correlations with temperature during the growing season, demonstrating that the physiological response to ca changes modulated d13C and masked the climate signal. Since 1970 higher d13C values revealed {iWUE} improvements at all the sites exceeding values expected by an active response to the ca increase alone. These patterns were related to upward trends in temperatures, indicating that other factors are reinforcing stomatal closure in these forests. Narrower rings during the second half of the 20th century than in previous centuries were observed at four sites and after 1970 at all sites, providing no evidence for a possible {CO}2 ‘fertilization’ effect on growth. The {iWUE} improvements found for all the forests, reflecting both a ca rise and warmer conditions, seem to be insufficient to compensate for the negative effects of the increasing water limitation on growth.},

	abstract = {Spatial and temporal patterns of spring break-up flooding in the Slave River Delta ({SRD}), Northwest Territories, are characterized during three years (2003–2005) using water isotope tracers and total inorganic suspended sediment ({TSS}) concentrations measured from lakewater samples collected shortly after the spring melt. Strongly contrasting spring melt periods led to a moderate flood in 2003, no flooding in 2004 and widespread flooding in 2005. Flooded lakes have isotopically-depleted υ18O (υ2H) signatures, ranging between 19Ð2‰ ( 145‰) and 17Ð1‰ ( 146‰) and most have high {TSS} concentrations ({\textgreater}10 mg L 1), while non-flooded lakes have more isotopically-enriched υ18O (υ2H) signatures, ranging between 18Ð2‰ ( 149‰) and 10Ð6‰ ( 118‰) and low {TSS} concentrations ({\textless}10 mg L 1). These results, in conjunction with the isotopic signatures of Slave River water and snowmelt, are used to estimate the proportion of river- or snowmelt-induced dilution in delta lakes during the spring of each study year. Calculations indicate river flooding caused dilution of ¾70–100\% in delta lakes, while snowmelt dilution in the absence of river flooding ranged from ¾0–56\%. A positive relationship exists between the spatial extent of spring flooding in the {SRD} and level and discharge on the Slave River and upstream tributaries, suggesting that upstream flow generation plays a key role in determining the magnitude of spring flooding in the {SRD}. Parallel variations in the 46-year instrumental Slave River discharge record and flood stratigraphy in the active delta indicate that there is potential for extending the flood history of the {SRD}, a development that will contribute to a more robust understanding of the drivers of historic, contemporary and future flood frequency in the delta.

Here, we structure the hydrological component of an aquatic ecosystem monitoring program that addresses concerns of Parks Canada (Vuntut National Park) and the Vuntut Gwitchin First Nation about changing water levels of Old Crow Flats ({OCF}), Yukon, Canada, a 5600-km2 thermokarst landscape recognized nationally and internationally for its ecological, historical, and cultural significance. The foundation of the monitoring program is 5 years (2007–2011) of water isotope data from 14 lakes situated in catchments that are representative of the land-cover and hydrological diversity of {OCF}. Isotopic compositions of input water (␦I) and evaporation-to-inflow (E/I) ratios, calculated using the coupled-isotope tracer method, provide key hydrological metrics for each lake over the 5-year sampling interval. From these time series, we identify monitoring lakes that are sensitive to changes in snowmelt, rainfall, and evaporation, and demonstrate the use of the Mann-Kendall test for determining statistically significant trends in the roles of these hydrological processes on lake-water balances. These approaches will serve to identify lake hydrological responses to climate change and variability from ongoing water isotope monitoring by Parks Canada, in partnership with the Vuntut Gwitchin Government, Wilfrid Laurier University, and the University of Waterloo.},

	abstract = {* 1The arctic environment is highly heterogeneous in terms of plant distribution and productivity. If we are to make regional scale predictions of carbon exchange it is necessary to find robust relationships that can simplify this variability. One such potential relationship is that of leaf area to photosynthetic {CO}2 flux at the canopy scale.
* 2In this paper we assess the effectiveness of canopy leaf area in explaining variation in gross primary productivity ({GPP}): (i) across different vegetation types; (ii) at various stages of leaf development; and (iii) under enhanced nutrient availability. To do this we measure net {CO}2 flux light response curves with a 1 × 1 m chamber, and calculate {GPP} at a photosynthetic photon flux density ({PPFD}) of 600 µmol m−2 s−1.
* 3At a subarctic site in Sweden, we report 10-fold variation in {GPP} among natural vegetation types with leaf area index ({LAI}) values of 0.05–2.31 m2 m−2. At a site of similar latitude in Alaska we document substantially elevated rates of {GPP} in fertilized vegetation.
* 4We can explain 80\% of the observed variation in {GPP} in natural vegetation (including vegetation measured before deciduous leaf bud burst) by leaf area alone, when leaf area is predicted from measurements of normalized difference vegetation index ({NDVI}).
* 5In fertilized vegetation the relative increase in leaf area between control and fertilized treatments exceeds the relative increase in {GPP}. This suggests that higher leaf area causes increased self-shading, or that lower leaf nitrogen per unit leaf area causes a reduction in the rate of photosynthesis.
* 6The results of this study indicate that canopy leaf area is an excellent predictor of {GPP} in diverse low arctic tundra, across a wide range of plant functional types.},

	abstract = {We conducted measurements of methane ({CH}4) emission and ecosystem respiration on {\textgreater}200 points across the Arctic coastal tundra near Barrow, Alaska, United States, in July 2007 and August 2008. This site contains broad diversity in tundra microtopography, including polygonal tundra, thaw lakes, and drained lake basins. In 2007, we surveyed {CH}4 emissions across this landscape, and found that soil water content was the strongest control of methane emission rate, such that emission rates rose exponentially with water content. However, there was considerable residual variation in {CH}4 emission in the wettest soils ({\textgreater}80\% volumetric water content) where {CH}4 emissions were highest. A statistical analysis of possible soil and plant controls on {CH}4 emission rates from these wet soils revealed that vegetation height (especially of Carex aquatilis) was the best predictor, with ecosystem respiration and permafrost depth as significant copredictors. To evaluate whether plant height served as a proxy for aboveground plant biomass, or gross primary production, we conducted a survey of {CH}4 emission rates from wet, Carex-dominated sites in 2008, coincidently measuring these candidate predictors. Surprisingly, vegetation height remained the best predictor of {CH}4 emission rates, with {CH}4 emissions rising exponentially with vegetation height. We hypothesize that taller plants have more extensive root systems that both stimulate more methanogenesis and conduct more pore water {CH}4 to the atmosphere. We anticipate that the magnitude of the climate change–{CH}4 feedback in the Arctic Coastal Plain will strongly depend on how permafrost thaw alters the ecology of Carex aquatilis.},

	abstract = {Abstract An atmospheric general circulation model with prescribed sea surface temperature and cloudiness was integrated for 50 years in order to study atmosphere-land surface interactions. The temporal variability of model soil moisture and precipitation have been studied in an effort to understand the interactions of these variables with other components of the climate system. Temporal variability analysis has shown that the spectra of monthly mean precipitation over land are close to white at all latitudes, with total variance decreasing poleward. In contrasts, the spectra of soil moisture are red, and become more red with increasing latitude. As a measure of this redness, half of the total variance of a composite tropical soil moisture spectrum occurs at periods longer than nine months, while at high latitudes, half of the total variance of a composite soil moisture spectrum occurs at periods longer than 22 months. The spectra of soil moisture also exhibit marked longitudinal variations. These spectral results may be viewed in the light of stochastic theory. The formulation of the {GFDL} soil moisture parameterization is mathematically similar to a stochastic process. According to this model, forcing of a system by an input white noise variable (precipitation) will yield an output variable (soil moisture) with a red spectrum, the redness of which is controlled by a damping term (potential evaporation). Thus, the increasingly red nature of the soil moisture spectra at higher latitudes is a result of declining potential evaporation values at higher latitudes. Physically, soil moisture excesses are dissipated more slowly at high latitudes where the energy available for evaporation is small. Some of the longitudinal variations in soil moisture spectra result from longitudinal variations in potential evaporation, while others are explicable in terms of the value of the ratio of potential evaporation to precipitation. Regions where this value is less than one are characterized by frequent runoff and short time scales of soil moisture variability. By preventing excessive positive anomalies of soil moisture, the runoff process hastens the return of soil moisture values to their mean state, thereby shortening soil moisture time scales. Through the use of a second {GCM} integration with prescribed soil moisture, it was shown that interactive sod moisture may substantially increase summer surface air temperature variability. Soil moisture interacts with the atmosphere primarily through the surface energy balance. The degree of soil saturation strongly influences the atmosphere of outgoing energy from the surface between the latent and sensible heat fluxes. Interactive soil moisture allows larger variations of these fluxes, thereby increasing the variance of surface air temperature. Because the flux of latent heat is directly proportional to potential evaporation under conditions of sufficient moisture, the influence of soil moisture on the atmosphere is greatest when the potential evaporation value is large. This occurs most frequently in the tropics and summer hemisphere extratropics.},

	abstract = {Climate change is having major impacts on northern regions. Shrub vegetation proliferation is an example of how land cover is being modified, which can influence ground biophysical conditions and the hydrology of lake-rich landscapes. These impacts are being investigated in Old Crow Flats, Yukon, traditional territory of the Vuntut Gwitchin First Nation who rely on the resources of this landscape to support their traditional lifestyle. Vegetation conditions of two 90-m x 90-m plots were investigated using dendrochronology and high-resolution multi-spectral images captured using an unmanned aviation vehicle ({UAV}). Dendrochronology results showed that the average age for shrub vegetation was 28 years old (standard deviation = 13.65). The dominant species in the two plots included green alder (Alnus viridis,), dwarf birch (Betula nan), and willow (Salix sp.). Red and near-infrared bands of the multi-spectral images were used to calculate normalized difference vegetation index values ({NDVI}) for the two plots, which is an indicator of plant chlorophyll and phytomass. Vegetation characteristics measured on the ground were compared to {NDVI} values to identify whether {NDVI} may be used to differentiate species and plant age. Results of this research show that coupling {UAV} technology with ground measurements may be highly useful for identifying shrub species and age in lake-rich Arctic landscapes such as Old Crow Flats, Yukon. Integrated approaches being developed here are enhancing hydroecological monitoring protocols, which are providing the basis to identify how
this landscape is responding to a changing climate.},

	abstract = {The use of Unmanned Aerial Vehicles ({UAVs}) in viticulture permits the capture of aerial Red-Green-Blue ({RGB}) images with an ultra-high spatial resolution. Recent studies have demonstrated that {RGB} images can be used to monitor spatial variability of vine biophysical parameters. However, for estimating these parameters, accurate and automated segmentation methods are required to extract relevant information from {RGB} images. Manual segmentation of aerial images is a laborious and time-consuming process. Traditional classification methods have shown satisfactory results in the segmentation of {RGB} images for diverse applications and surfaces, however, in the case of commercial vineyards, it is necessary to consider some particularities inherent to canopy size in the vertical trellis systems ({VSP}) such as shadow effect and different soil conditions in inter-rows (mixed information of soil and weeds). Therefore, the objective of this study was to compare the performance of four classification methods (K-means, Artificial Neural Networks ({ANN}), Random Forest ({RForest}) and Spectral Indices ({SI})) to detect canopy in a vineyard trained on {VSP}. Six flights were carried out from post-flowering to harvest in a commercial vineyard cv. Carménère using a low-cost {UAV} equipped with a conventional {RGB} camera. The results show that the {ANN} and the simple {SI} method complemented with the Otsu method for thresholding presented the best performance for the detection of the vine canopy with high overall accuracy values for all study days. Spectral indices presented the best performance in the detection of Plant class (Vine canopy) with an overall accuracy of around 0.99. However, considering the performance pixel by pixel, the Spectral indices are not able to discriminate between Soil and Shadow class. The best performance in the classification of three classes (Plant, Soil, and Shadow) of vineyard {RGB} images, was obtained when the {SI} values were used as input data in trained methods ({ANN} and {RForest}), reaching overall accuracy values around 0.98 with high sensitivity values for the three classes.},

The developed model is able to recognize 13 different types of plant diseases out of healthy leaves, with the ability to distinguish plant leaves from their surroundings. According to our knowledge, this method for plant disease recognition has been proposed for the first time. All essential steps required for implementing this disease recognition model are fully described throughout the paper, starting from gathering images in order to create a database, assessed by agricultural experts. Caffe, a deep learning framework developed by Berkley Vision and Learning Centre, was used to perform the deep {CNN} training. The experimental results on the developed model achieved precision between 91\% and 98\%, for separate class tests, on average 96.3\%.},

	abstract = {High-latitude ecosystems store approximately 1700 Pg of soil carbon (C), which is twice as much C as is currently contained in the atmosphere. Permafrost thaw and subsequent microbial decomposition of permafrost organic matter could add large amounts of C to the atmosphere, thereby influencing the global C cycle. The rates at which C is being released from the permafrost zone at different soil depths and across different physiographic regions are poorly understood but crucial in understanding future changes in permafrost C storage with climate change. We assessed the inherent decomposability of C from the permafrost zone by assembling a database of long-term ({\textgreater}1 year) aerobic soil incubations from 121 individual samples from 23 high-latitude ecosystems located across the northern circumpolar permafrost zone. Using a three-pool (i.e., fast, slow and passive) decomposition model, we estimated pool sizes for C fractions with different turnover times and their inherent decomposition rates using a reference temperature of 5 °C. Fast cycling C accounted for less than 5\% of all C in both organic and mineral soils whereas the pool size of slow cycling C increased with C : N. Turnover time at 5 °C of fast cycling C typically was below 1 year, between 5 and 15 years for slow turning over C, and more than 500 years for passive C. We project that between 20 and 90\% of the organic C could potentially be mineralized to {CO}2 within 50 incubation years at a constant temperature of 5 °C, with vulnerability to loss increasing in soils with higher C : N. These results demonstrate the variation in the vulnerability of C stored in permafrost soils based on inherent differences in organic matter decomposability, and point toward C : N as an index of decomposability that has the potential to be used to scale permafrost C loss across landscapes.},

Spatially explicit estimates of {ALT} can provide critically needed data for parameterization, initialization, and evaluation of Arctic terrestrial models. In this work, we demonstrate a new approach using high-resolution remotely sensed data for estimating centimeter-scale {ALT} in a 5 km2 area of ice-wedge polygon terrain in Barrow, Alaska. We use a simple regression-based, machine learning data-fusion algorithm that uses topographic and spectral metrics derived from multisensor data ({LiDAR} and {WorldView}-2) to estimate {ALT} (2 m spatial resolution) across the study area. Comparison of the {ALT} estimates with ground-based measurements, indicates the accuracy (r2 = 0.76, {RMSE} ±4.4 cm) of the approach. While it is generally accepted that broad climatic variability associated with increasing air temperature will govern the regional averages of {ALT}, consistent with prior studies, our findings using high-resolution {LiDAR} and {WorldView}-2 data, show that smaller-scale variability in {ALT} is controlled by local eco-hydro-geomorphic factors. This work demonstrates a path forward for mapping {ALT} at high spatial resolution and across sufficiently large regions for improved understanding and predictions of coupled dynamics among permafrost, hydrology, and land-surface processes from readily available remote sensing data.},

	abstract = {{ABSTRACT} Arctic and sub-arctic watersheds are undergoing significant changes due to recent climate warming and degrading permafrost, engendering enhanced monitoring of arctic rivers. Smaller catchments provide understanding of discharge, solute flux and groundwater recharge at the process level that contributes to an understanding of how larger arctic watersheds are responding to climate change. The North Klondike River, located in west central Yukon, is a sub-alpine permafrost catchment, which maintains an active hydrological monitoring station with a record of {\textgreater}40 years. In addition to being able to monitor intra-annual variability, this data set allows for more complex analysis of streamflow records. Streamflow data, geochemistry and stable isotope data for 2014 show a groundwater-dominated system, predominantly recharged during periods of snowmelt. Radiocarbon is shown to be a valuable tracer of soil zone recharge processes and carbon sources. Winter groundwater baseflow contributes 20 \% of total annual discharge, and accounts for up to 50 \% of total river discharge during the spring and summer months. Although total stream discharge remains unchanged, mean annual groundwater baseflow has increased over the 40-year monitoring period. Wavelet analysis reveals a catchment that responds to El Niño and longer solar cycles, as well as climatic shifts such as the Pacific Decadal Oscillation.

	abstract = {Studies from a variety of disciplines document recent change in the northern high-latitude environment. Prompted by predictions of an amplified response of the Arctic to enhanced greenhouse forcing, we present a synthesis of these observations. Pronounced winter and spring warming over northern continents since about 1970 is partly compensated by cooling over the northern North Atlantic. Warming is also evident over the central Arctic Ocean. There is a downward tendency in sea ice extent, attended by warming and increased areal extent of the Arctic Ocean's Atlantic layer. Negative snow cover anomalies have dominated over both continents since the late 1980s and terrestrial precipitation has increased since 1900. Small Arctic glaciers have exhibited generally negative mass balances. While permafrost has warmed in Alaska and Russia, it has cooled in eastern Canada. There is evidence of increased plant growth, attended by greater shrub abundance and northward migration of the tree line. Evidence also suggests that the tundra has changed from a net sink to a net source of atmospheric carbon dioxide. Taken together, these results paint a reasonably coherent picture of change, but their interpretation as signals of enhanced greenhouse warming is open to debate. Many of the environmental records are either short, are of uncertain quality, or provide limited spatial coverage. The recent high-latitude warming is also no larger than the interdecadal temperature range during this century. Nevertheless, the general patterns of change broadly agree with model predictions. Roughly half of the pronounced recent rise in Northern Hemisphere winter temperatures reflects shifts in atmospheric circulation. However, such changes are not inconsistent with anthropogenic forcing and include generally positive phases of the North Atlantic and Arctic Oscillations and extratropical responses to the El-Niño Southern Oscillation. An anthropogenic effect is also suggested from interpretation of the paleoclimate record, which indicates that the 20th century Arctic is the warmest of the past 400 years.},

	abstract = {Changes in active layer thickness ({ALT}) over northern high-latitude permafrost regions have important impacts on the surface energy balance, hydrologic cycle, carbon exchange between the atmosphere and the land surface, plant growth, and ecosystems as a whole. This study examines the 20th century variations of {ALT} for the Ob, Yenisey, and Lena River basins. {ALT} is estimated from historical soil temperature measurements from 17 stations (1956–1990, Lena basin only), an annual thawing index based on both surface air temperature data (1901–2002) and numerical modeling (1980–2002). The latter two provide spatial fields. Based on the thawing index, the long-term average (1961–1990) {ALT} is about 1.87 m in the Ob, 1.67 in the Yenisey, and 1.69 m in the Lena basin. Over the past several decades, {ALT} over the three basins shows positive trends, but with different magnitudes. Based on the 17 stations, {ALT} increased about 0.32 m between 1956 and 1990 in the Lena. To the extent that results based on the soil temperatures represent ground “truth,” {ALT} obtained from both the thawing index and numerical modeling is underestimated. It is widely believed that {ALT} will increase with global warming. However, this hypothesis needs further refinement since {ALT} responds primarily to summer air temperature while observed warming has occurred mainly in winter and spring. It is also shown that {ALT} exhibits complex and inconsistent responses to variations in snow cover.},

	abstract = {Growing evidence indicates that lake-dominated ecosystems at high latitudes are undergoing significant hydrological changes. Research examining these changes is complicated because both thermokarst and climatic processes likely influence lake dynamics. To examine the relative impacts of these processes in permafrost landscapes, we investigated the dynamics of lake area and number in Old Crow Flats ({OCF}), Yukon using historical air photos and satellite imagery. Between 1951 and 2007, {OCF} experienced a decline of {\textasciitilde}6000 ha in total lake area but gained 232 lakes. Close to half (49\%) of the difference in lake area was driven by the rapid and persistent drainage of 38 large lakes. These catastrophic drainages were associated with new or enlarged outlet channels, resulted in the formation of numerous residual ponds, and were likely driven by thermokarst processes. Our analysis shows that catastrophic lake drainages have become more than 5 times more frequent in recent decades. These changes are likely related to the impacts of increased temperature and precipitation on thermokarst processes. Fifty-nine of the 170 intensively studied lakes showed either large bidirectional fluctuations or gradual cumulative declines. These changes affected a much smaller portion of {OCF} and were likely driven by interactions between increased precipitation and temperature and individual catchment characteristics. To anticipate landscape-scale changes in these systems, and assess their impact on hydrology, wildlife habitat, and carbon storage, field research is required to better characterize the mechanisms responsible for changes.},

	title = {Isotopic evidence for recent hydrological shifts in source waters of shallow lakes in northern freshwater landscapes.},
	abstract = {In northern Canada, shallow-lake-rich freshwater landscapes provide key habitat for many wildlife species and play a vital role in the traditional use of the land by local indigenous communities. Changes in precipitation have the potential to substantially alter the hydrological conditions of these shallow lakes. Here we compare multiple years of measurements of lake water oxygen isotope composition (δ18Omes) with surface sediment cellulose-inferred lake water oxygen isotope composition (δ18Oinf) for {\textasciitilde}80 lakes in two of Canada’s largest lake-rich thermokarst landscapes – Old Crow Flats ({OCF}), Yukon, and western Hudson Bay Lowlands ({HBL}), Manitoba. Results reveal a strikingly coherent pattern of recent hydrological change in these two landscapes. In {OCF}, δ18Oinf values from snowmelt-dominated lakes align reasonably well with the 2007-2008 δ18Omes values from the early ice-free season, as expected. In contrast, δ18Oinf from rainfall-dominated lakes are systematically lower (i.e., more 18O-depleted) relative to δ18Omes. Climate data indicate that the winter of 2007-08 had markedly lower snowfall compared to the long-term mean, whereas winters immediately prior to our water sample collections were characterized by snowfall equal to or greater than the long-term mean. Thus, we speculate that the isotopic offset between δ18Oinf and δ18Omes for some of the lakes is due to a shift to more rainfall-dominated precipitation. Similar results have been obtained from lakes in {HBL}. Here too, about 40\% of the sampled lakes contain δ18Oinf values that are lower than δ18Omes values from 2010-2012, which may also reflect a recent shift to more rainfall-dominated precipitation. These findings suggest that some lakes in our study areas received less snowmelt during the water sampling years in comparison to the time interval captured in the surface-sediments. Notably, a few lakes in {HBL} lost all of their water to evaporation during mid-summer 2010, fuelling concerns that reduction in snowmelt and an increase in the length of the ice-free season in these landscapes may lead to an increase in the occurrence of lake desiccation.},
