Carbon emission from thermokarst lakes in NE European tundra [PDF]

, 2021
International audienceEmission of greenhouse gases (GHGs) from inland waters is recognized as highly important and an understudied part of the terrestrial carbon (C) biogeochemical cycle.

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.

Panarctic lakes exerted a small positive feedback on early Holocene warming due to deglacial release of methane

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

Limnological properties of thermokarst lakes in Central Yakutia sampled between 2018-2019 [PDF]

, 2020
This dataset compiles selected limnological properties of a series of thermokarst (thaw) lakes in Central Yakutia (Eastern Siberia). These properties were measured during fall 2018 (September), winter 2019 (March-April), spring 2019 (May), and summer ...

Methane emissions from northern lakes under climate change: a review

SN Applied Sciences, 2021
Northern lakes are important sources of CH4 in the atmosphere under the background of permafrost thaw and winter warming. We synthesize studies on thermokarst lakes, including various carbon sources for CH4 emission and the influence of thermokarst ...

Terrestrial-aquatic connectivity structures microbial communities during the formation of thermokarst lakes. [PDF]

ISME Commun
Rising air temperatures and permafrost degradation drive the erosion of palsas (permafrost mounds mainly composed of frozen peat and ice layers) and lead to the formation of thermokarst ponds and lakes, known for their high greenhouse gas (GHG) emissions.

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.

Decadal-scale hotspot methane ebullition within lakes following abrupt permafrost thaw

Environmental Research Letters, 2021
Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO _2 ) and methane (CH _4 ) that enhance climate warming ...

Automated Identification of Thermokarst Lakes Using Machine Learning in the Ice-Rich Permafrost Landscape of Central Yakutia (Eastern Siberia)

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 ...

Geocryological conditions triggering thermokarst processes in Central Yakutia [PDF]

E3S Web of Conferences, 2020
The use of the Central Yakutia Landsat images revealed an increase in the area of thermokarst lakes by two times for the Suola and Taatta River basins and a quarter times in the Tanda River basin during the period 2000-2019.
