Sedimentological, biogeochemical and hydrochemical characteristics of deep drilled thermokarst lagoon sediment cores, Bykovsky Peninsula, Lena Delta area

, 2020
Current warming, sea-level rise, coastal erosion and accelerated permafrost thaw is leading to increasing thermokarst lagoon formation along wide parts of the arctic coast. Entering seawater affects the temperature and salinity of former thermokarst lake

Dissolved organic carbon content in thawed sediments underneath a Yedoma and Alas thermokarst lake in Eastern Siberia

, 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 ...

Shallow carbon storage in ancient buried thermokarst in the South Kara Sea

Scientific Reports, 2018
Geophysical data from the South Kara Sea reveal U-shaped erosional structures buried beneath the 50–250 m deep seafloor of the continental shelf across an area of ~32 000 km2.

Analysis on physical and chemical properties of water in thermokarst lakes along Qinghai-Tibet engineering corridor

Shui kexue jinzhan, 2014
Formation and development of thermokarst lakes have great influence on the cold region environment,and its lateral heat erosion can cause the embankment instability in permafrost regions.

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

, 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 ...

Evaluation of the energy budget of thermokarst lake in permafrost regions of the Qinghai–Tibet Plateau

Advances in Climate Change Research
Thermokarst lake formation accelerates permafrost degradation due to climate warming, thereby releasing significant amounts of carbon into the atmosphere, complicating hydrological cycles, and causing environmental damage.

Thermokarst and thermal erosion: Degradation of Siberian ice-rich permafrost [PDF]

, 2012
Current climate warming is affecting arctic regions at a faster rate than the rest of the world. This has profound effects on permafrost that underlies most of the arctic land area. Permafrost thawing can lead to the liberation of considerable amounts of

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 ...

Thermokarst terrain: pan-Arctic distribution and soil carbon vulnerability

, 2015
Development of thermokarst landforms through the thawing of ice-rich permafrost soils is expected to accelerate in the northern hemisphere due to ongoing climate change.
