Evidence of multiple thermokarst lake generations from an 11 800-year-old permafrost core on the northern Seward Peninsula, Alaska [PDF]

, 2016
Permafrost degradation influences the morphology, biogeochemical cycling and hydrology of Arctic landscapes over a range of time scales. To reconstruct temporal patterns of early to late Holocene permafrost and thermokarst dynamics, site-specific palaeo-

Thermokarst and precipitation drive changes in the area of lakes and ponds in the National Parks of northwestern Alaska, 1984–2018

Arctic, Antarctic, and Alpine Research, 2019
Lakes and ponds are important ecosystem components in arctic lowlands, and they are prone to rapid changes in surface area by thermokarst expansion and by sudden lake drainage. The 30 m resolution Landsat record (1984–2018) was used to derive a record of

Thermokarst lake sediment as indicator of climate variations: precise environmental archive or wishful thinking? [PDF]

, 2015
In polar permafrost environments lake sediments are commonly used to reconstruct past environmental conditions and are sometimes the only high-resolution and continuous archive available where ice caps, glaciers or trees are missing. However, many of the

Mapping Thermokarst Lakes Using Sentinel-2 Imagery in the Qinghai–Tibet Engineering Corridor in 2020

Remote Sensing
Accurate mapping of thermokarst lakes in the Qinghai–Tibet Engineering Corridor is important for understanding permafrost degradation and assessing environmental risks to major infrastructure.

Periphytic diatom community structure in thermokarst ecosystems of Nunavik (Québec, Canada)

Arctic Science, 2018
Climate change is causing rapid permafrost degradation across Arctic and subarctic regions, resulting in changes in the size, abundance, and structure of thermokarst (thaw) ponds and lakes.

The evolution of methane production rates from young to mature thermokarst lakes [PDF]

Biogeosciences
Thermokarst lakes, formed by permafrost thaw in the Arctic, are hotspots for methane (CH4) and carbon dioxide (CO2) emissions and are expected to double permafrost carbon emissions by the end of the century.

An examination of the influence of thermokarst activity on Artic 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.
