Isotopic composition of ground ice, ebullition gases and thermokarst lake water, North America [PDF]

, 2012
Thermokarst lakes are thought to have been an important source of methane (CH4) during the last deglaciation when atmospheric CH4 concentrations increased rapidly.

An examination of the influence of thermokarst activity on arctic lake sediment methanogenesis [PDF]

, 2009
Accelerated warming in the Arctic contributes to the formation of landscape features known as thermokarsts, or ground surface depressions created by the thermal degradation of permafrost.

Detecting methane ebullition on thermokarst lake ice using high resolution optical aerial imagery [PDF]

, 2015
Thermokarst lakes are important emitters of methane, a potent greenhouse gas. However, accurate estimation of methane flux from thermokarst lakes is difficult due to their remoteness and observational challenges associated with the heterogeneous nature ...

Application of the Red Edge Water Index for Extracting Thermokarst Lakes and Detecting Drainage Events on the Qinghai–Tibet Plateau

Atmosphere
Thermokarst lakes play a crucial role in regulating hydrological, ecological, and biogeochemical processes in permafrost regions. However, due to the limited spatial resolution of earlier satellite imagery, small thermokarst lakes—highly sensitive to ...

Lake water balance of a thermokarst lake on Kurungnakh, Lena delta, northern Siberia [PDF]

, 2014
Hydrological processes in permafrost regions are still hard to represent in models because of a lack of sufficient process understanding based on field observations in different permafrost settings.

Processes controlling thermokarst lake expansion rates on the Arctic coastal plain of Northern Alaska [PDF]

, 2017
Thesis (M.S.) University of Alaska Fairbanks, 2017Thermokarst lakes are a dominant factor of landscape scale processes and permafrost dynamics in the otherwise continuous permafrost region of the Arctic Coastal Plain (ACP) of northern Alaska. Lakes cover

Emerging thermokarst lakes amplify benthic activity and carbon mobilization in a continuous permafrost landscape

Environmental Research Communications
Continuous permafrost zones are experiencing accelerated thaw due to Arctic warming, resulting in considerable greenhouse gas (GHG) emissions that significantly impact climate feedbacks.
