Historical archived satellite images were compared with contemporary satellite data to track ongoing changes in more than 10,000 large lakes in rapidly warming Siberia. A widespread decline in lake abundance and area has occurred since 1973, despite slight precipitation increases to the region. 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… 

The summer hydrology of a small upland tundra thaw lake: implications to lake drainage

The phenomenon of thaw lake disappearance through rapid drainage has been identified as a potential issue for many circumpolar Arctic regions. These drainage events and the associated flood waves

Controls on recent Alaskan lake changes identified from water isotopes and remote sensing

High‐latitude lakes are important for terrestrial carbon dynamics and waterfowl habitat driving a need to better understand controls on lake area changes. To identify the existence and cause of

Changing Lake Dynamics Indicate a Drier Arctic in Western Greenland

The water balance of the Arctic tundra is shifting as permafrost stability, seasonality, and the ratio of precipitation to evaporation respond to amplified Arctic warming. While in some northern

Landscape influences on climate‐related lake shrinkage at high latitudes

Results indicate that postfire processes such as permafrost degradation, which also results from a warming climate, may promote lake drainage, particularly in coarse-textured soils and farther from rivers where overland flooding is less likely and downslope flow paths and negative hydraulic gradients between surface water and groundwater systems are more common.

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

Observations of changes in surface water over the western Siberia lowland

We analyse the evolution of the fraction of water surface (FWS), derived by SSM/I between 1988 and 2002 over the Western Siberia Lowland. This whole region exhibits an increase in the amount of FWS

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

Permafrost thaw drives surface water decline across lake-rich regions of the Arctic

Lakes constitute 20–40% of Arctic lowlands, the largest surface water fraction of any terrestrial biome. These lakes provide crucial habitat for wildlife, supply water for remote Arctic communities

Changes in lake area in response to thermokarst processes and climate in Old Crow Flats, Yukon

Growing evidence indicates that lake‐dominated ecosystems at high latitudes are undergoing significant hydrological changes. Research examining these changes is complicated because both thermokarst



Increasing River Discharge to the Arctic Ocean

Synthesis of river-monitoring data reveals that the average annual discharge of fresh water from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999, a large-scale change in freshwater flux.

Recent temperature and precipitation increases in West Siberia and their association with the Arctic Oscillation

Surface air temperature and precipitation records for the years 1958-1999 from ten meteorological stations located throughout West Siberia are used to identify climatic trends and determine to what

Observational Evidence of Recent Change in the Northern High-Latitude Environment

Studies from a variety of disciplines documentrecentchange in the northern high-latitude environment.Prompted by predictions of an amplified response oftheArctic to enhanced greenhouse forcing, we

Siberian Peatlands a Net Carbon Sink and Global Methane Source Since the Early Holocene

Interpolar methane gradient (IPG) data from ice cores suggest the “switching on” of a major Northern Hemisphere methane source in the early Holocene, and Russia's West Siberian Lowland represents a long-term carbon dioxide sink and global methane source since theEarly Holocene.

The thermal regime of soils in the north of Western Siberia

The results of long‐term stationary observations upon the thermal regime of soils in natural and anthropogenically‐disturbed tundra and northern taiga landscapes in the north of Western Siberia are

Shrinking thermokarst ponds and groundwater dynamics in discontinuous permafrost near council, Alaska

The purpose of this study was to characterize the geomorphological processes controlling the dynamics of ponds and to identify and characterize groundwater infiltration and surface water dynamics for
