Lake‐Atmosphere Heat Flux Dynamics of a Thermokarst Lake in Arctic Siberia [PDF]
Journal of Geophysical Research: Atmospheres, 2018 AbstractWe conducted eddy covariance measurements from April to August 2014 on a Siberian thermokarst lake. The study site is located in the Lena River Delta and characterized as a floating ice lake. Heat fluxes differed in magnitudes, directions and temporal patterns depending on the lake surface conditions (“frozen” ice cover, ice cover melt, and ...

Cumulative greenhouse gas production in thawed sediments underneath a Yedoma and Alas thermokarst lake in Eastern Siberia [PDF]
, 2021 This dataset describes two 17 m long sediment cores taken from beneath two thermokarst lakes in the Yukechi Alas, Central Yakutia, Russia. The first core was taken from below an Alas thermokarst lake (YU-L7; 61.76397°N, 130.46442°E) and the second core ...

Spatial analyses of thermokarst lakes and basins in Yedoma landscapes of the Lena Delta [PDF]
The Cryosphere, 2011 Distinctive periglacial landscapes have formed in late-Pleistocene ice-rich permafrost deposits (Ice Complex) of northern Yakutia, Siberia. Thermokarst lakes and thermokarst basins alternate with ice-rich Yedoma uplands.

Remote Sensing, 2023 The current rate and magnitude of temperature rise in the Arctic are disproportionately high compared to global averages. Along with other natural and anthropogenic disturbances, this warming has caused widespread permafrost degradation and soil ...

Periglacial Lake Origin Influences the Likelihood of Lake Drainage in Northern Alaska
Remote Sensing, 2021 Nearly 25% of all lakes on earth are located at high latitudes. These lakes are formed by a combination of thermokarst, glacial, and geological processes.

Biogeochemical parameters of thawed sediments underneath a Yedoma and Alas thermokarst lake in Eastern Siberia, version 2 [PDF]
, 2022 This dataset describes two 17 m long sediment cores taken from beneath two thermokarst lakes in the Yukechi Alas, Central Yakutia, Russia. The first core was taken from below an Alas thermokarst lake (YU-L7; 61.76397°N, 130.46442°E) and the second core ...

Table1_From permafrost soil to thermokarst lake sediment: A view from C:N:P stoichiometry.XLSX [PDF]
, 2022 Thermokarst lakes are formed as a result of thawing ice-rich permafrost, transforming vast permafrost soil into lake sediment and changing the biogeochemistry of carbon (C), nitrogen (N), and phosphorus (P).

Evolution of a High-Mountain Thermokarst Lake in the Swiss Alps [PDF]
Arctic, Antarctic, and Alpine Research, 2001 Thermokarst lakes, a characteristic landscape element of the Arctic, are rarely found outside arctic situations. Here, a 30-yr photogrammetric monitoring series of a thermokarst lake in the Gruben area, Swiss Alps, is presented. The lake, situated in an environment of dead-ice remains and creeping permafrost, reached a final size of ca.
