Simulating thermokarst lakes [PDF]

Eos, Transactions American Geophysical Union, 2012
Thermokarst lakes, which form from thawing permafrost, alter landscapes and hydrology and can release significant amounts of methane to the atmosphere. To learn more about the dynamics of thermokarst lakes, Kessler et al. created a three‐dimensional numerical model of these lakes that includes the surrounding topography.

Geographic and seasonal variation of dissolved methane and aerobic methane oxidation in Alaskan lakes [PDF]

Biogeosciences, 2015
Methanotrophic bacteria play an important role oxidizing a significant fraction of methane (CH4) produced in lakes. Aerobic CH4 oxidation depends mainly on lake CH4 and oxygen (O2) concentrations, in such a manner that higher MO rates are usually found ...

Thermokarst-lake methanogenesis along a complete talik profile [PDF]

Biogeosciences, 2015
Abstract. Thermokarst (thaw) lakes emit methane (CH4) to the atmosphere formed from thawed permafrost organic matter (OM), but the relative magnitude of CH4 production in surface lake sediments vs. deeper thawed permafrost horizons is not well understood.

Biogeography and environmental drivers of zooplankton communities in permafrost-affected lakes on the Qinghai-Tibet Plateau

Global Ecology and Conservation, 2022
Global warming is accelerating permafrost thaw, forming new thermokarst lakes and substantially influencing the old ones. However, the biological communities in thermokarst lakes on the Qinghai-Tibet Plateau (QTP) are rarely studied.

A synthesis of methane dynamics in thermokarst lake environments [PDF]

Earth-Science Reviews, 2020
Abstract Greenhouse gas emissions from physical permafrost thaw disturbance and subsidence, including the formation and expansion of thermokarst (thaw) lakes, may double the magnitude of the permafrost carbon feedback this century. These processes are not accounted for in current global climate models.

Evolution of thermokarst in East Siberian ice-rich permafrost [PDF]

, 2013
Thermokarst lakes and basins are major components of ice-rich permafrost landscapes in East Siberian coastal lowlands and are regarded as indicators of regional climatic changes.

Biogeochemical Distinctiveness of Peatland Ponds, Thermokarst Waterbodies, and Lakes [PDF]

, 2021
Small lentic freshwater ecosystems play a disproportionate role in global biogeochemical cycles by processing large amounts of carbon (C), nitrogen (N), and phosphorus (P), but it is unlikely that they behave as one homogenous group for the purpose of ...
