Remote Sensing, 2021 Thermokarst lakes are widespread in Arctic lowlands. Under a warming climate, landscapes with highly ice-rich Yedoma Ice Complex (IC) deposits are particularly vulnerable, and thermokarst lake area dynamics serve as an indicator for their response to ...

Ecological stability of zooplankton communities in changing arctic lakes over three decades. [PDF]
EcologyAbstract In the Arctic, rapid warming is altering disturbance regimes, creating an urgent need to assess the ecological stability of these relatively pristine ecosystems. The Arctic landscape has thousands of lakes that are experiencing both gradual, persistent disturbances (e.g., warming) and increased frequency and intensity of pulse disturbances (e ...

From permafrost soil to thermokarst lake sediment: A view from C:N:P stoichiometry
Frontiers in Environmental Science, 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).

A fully automatic framework for sub-pixel mapping of thermokarst lakes using Sentinel-2 images
Science of Remote Sensing, 2023 Mapping and monitoring thermokarst lakes are crucial to understanding the impact of climate change on permafrost regions and quantifying permafrost-related carbon emissions. Several automatic methods based on remote sensing images have been developed for

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 ...

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.

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.

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 ...

, 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 ...

Communications Earth & Environment, 2023 Climate-driven permafrost thaw can release ancient carbon to the atmosphere, begetting further warming in a positive feedback loop. Polar ice core data and young radiocarbon ages of dissolved methane in thermokarst lakes have challenged the importance of
