Climate‐related declines in lake area have been identified across circumpolar regions and have been characterized by substantial spatial heterogeneity. An improved understanding of the mechanisms underlying lake area trends is necessary to predict where change is most likely to occur and to identify implications for high latitude reservoirs of carbon. Here, using a population of ca. 2300 lakes with statistically significant increasing and decreasing lake area trends spanning longitudinal and… 
Surface Water Dynamics and Rapid Lake Drainage in the Western Canadian Subarctic (1985–2020)
The area and distribution of surface water are shifting rapidly in many regions across the circumpolar Arctic. In this study, we explore the effects of climate and terrain factors on the area of
Impacts of Climate Change on Tibetan Lakes: Patterns and Processes
Four modes of lake change in response to climate and associated changes were identified; lake expansion was predominantly attributed to increased precipitation and glacier melting, whereas lake shrinkage was a main consequence of a drier climate or permafrost degradation.
Recent warming reverses forty-year decline in catastrophic lake drainage and hastens gradual lake drainage across northern Alaska
Lakes represent as much as ∼25% of the total land surface area in lowland permafrost regions. Though decreasing lake area has become a widespread phenomenon in permafrost regions, our ability to
Landsat-Based Trend Analysis of Lake Dynamics across Northern Permafrost Regions
A methodology based on machine-learning based classification of robust trends of multi-spectral indices of Landsat data (TM, ETM+, OLI) and object-based lake detection is presented to analyze and compare the individual, local and regional lake dynamics of four different study sites in the northern permafrost zone from 1999 to 2014.
Temporal Behavior of Lake Size-Distribution in a Thawing Permafrost Landscape in Northwestern Siberia
Investigation of potential shifts in thermokarst lake size-distributions over three distinct time periods in northwestern Siberia revealed fluctuations in total area and number of lakes over time, indicating that spatially variable change effects on local permafrost conditions have driven the individual lake changes that have indeed occurred over time.
Landsat-based lake distribution and changes in western Alaska permafrost regions between the 1970s and 2010s
Lakes are an important ecosystem component and geomorphological agent in northern high latitudes and it is important to understand how lake initiation, expansion and drainage may change as high

ABSTRACT Lakes and ponds are important ecosystem components in arctic lowlands, and they are prone to rapid changes in surface area by thermokarst expansion and by sudden lake drainage. The 30 m
Inland waters and their role in the carbon cycle of Alaska.
This work combined available data sets and applied consistent methodologies to estimate river lateral C export to the coast, river and lake carbon dioxide and methane emissions, and C burial in lakes for the six major hydrologic regions in the state of Alaska.
Spatiotemporal remote sensing of ecosystem change and causation across Alaska
The historical sensitivity of Alaska's ecosystems to environmental change and anthropogenic disturbances is characterized using expert knowledge, remote sensing data, and spatiotemporal analyses and modeling to fill a critical gap in the understanding of historical and potential future trajectories of change in northern high-latitude regions.


Mechanisms influencing changes in lake area in Alaskan boreal forest
During the past ∼50 years, the number and area of lakes have declined in several regions in boreal forests. However, there has been substantial finer‐scale heterogeneity; some lakes decreased in
Shrinking lakes of the Arctic: Spatial relationships and trajectory of change
Over the past 3 decades the Arctic has seen substantial warming. Previous local to regional scale studies have shown a considerable reduction in the size of lakes in this region. The subsequent
Linkages between lake shrinkage/expansion and sublacustrine permafrost distribution determined from remote sensing of interior Alaska, USA
Linkages between permafrost distribution and lake surface‐area changes in cold regions have not been previously examined over a large scale because of the paucity of subsurface permafrost
Modern thermokarst lake dynamics in the continuous permafrost zone, northern Seward Peninsula, Alaska
[1] Quantifying changes in thermokarst lake extent is of importance for understanding the permafrost-related carbon budget, including the potential release of carbon via lake expansion or
Temporal and spatial pattern of thermokarst lake area changes at Yukon Flats, Alaska
To better understand the linkage between lake area change, permafrost conditions and intra‐annual and inter‐annual variability in climate, we explored the temporal and spatial patterns of lake area
Tracking hydrological responses of a thermokarst lake in the Old Crow Flats (Yukon Territory, Canada) to recent climate variability using aerial photographs and paleolimnological methods
Recent studies using remote sensing analysis of lake‐rich thermokarst landscapes have documented evidence of declining lake surface area in response to recent warming. However, images alone cannot

[1] Over the past 50 years, Alaska has experienced a warming climate with longer growing seasons, increased potential evapotranspiration, and permafrost warming. Research from the Seward Peninsula
Disappearing Arctic Lakes
The spatial pattern of lake disappearance suggests (i) that thaw and "breaching" of permafrost is driving the observed losses, by enabling rapid lake draining into the subsurface; and (ii) a conceptual model in which high-latitude warming ofpermafrost triggers an initial but transitory phase of lake and wetland expansion, followed by their widespread disappearance.
Peat accumulation in drained thermokarst lake basins in continuous, ice-rich permafrost, northern Seward Peninsula, Alaska
Thermokarst lakes and peat-accumulating drained lake basins cover a substantial portion of Arctic lowland landscapes, yet the role of thermokarst lake drainage and ensuing peat formation in

Lakes, of average size 33–ha, occupy a quarter of the surface area of Richards Island, Northwest Territories. Most of the lakes have a central pool deeper than the thickness of winter ice, and many
