Organic carbon content in degrading permafrost beneath expanding thermokarst lakes

, 2014
Arctic lakes are globally significant sources of methane, resulting from anaerobic decomposition of thawed organic matter in lake bottoms. We examined patterns of permafrost degradation near thermokarst lakeshores in the tundra of Old Crow Flats, a 5600 ...

Plant indication of thermocarst forms in palsa mires in the south of Nature Park Numto (West Siberia)

Социально-экологические технологии, 2019
Currently, palsa mires in the southern limit of circumpolar permafrost zone are characterized by an increased intensity of thermokarst processes. In the south of Nature Park Numto the cyclic character of frozen mound formation was replaced by their ...

Methodical issues of evaluating methane capacity in small thermokarst lakes of Western Siberia permafrost

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the paper is caused by the need to develop methodological issues of using mathematical modeling and ultrahigh resolution satellite imagery to assess the accumulation of methane in small thermokarst lakes in the permafrost zone, which are

Preliminary Investigation of Thermokarst Development on the North Slope, Alaska [PDF]

, 1963
The North Slope of Alaska is extensively featured by a characteristic form of morphology designated thermokarst . Briefly, thermokarst is a term applied to a karst-like topography formed in permafrost regions that have had extensive thaw.

Initial Conceptualization and Simulation of Arctic Tundra Landscape Evolution Using the Alaska Thermokarst Model

, 2014
Thermokarst topography forms whenever ice-rich permafrost thaws and the ground subsides due to the volume loss when excess ground ice transitions to water.
