Spatio-Temporal Analysis of Gyres in Oriented Lakes on the Arctic Coastal Plain of Northern Alaska Based on Remotely Sensed Images

open access: yesRemote Sensing, 2014
The formation of oriented thermokarst lakes on the Arctic Coastal Plain of northern Alaska has been the subject of debate for more than half a century.

Thermokarst lakes increased atmospheric methane levels [PDF]

open access: yesEos, Transactions American Geophysical Union, 2012
Ice cores taken from Greenland indicate that during the last deglaciation, approximately 10,000 years ago, increases in temperature occurred at the same times as increases in atmospheric methane, a potent greenhouse gas. The source of the increase in atmospheric methane is still debated, but it has been suggested that thermokarst lakes, which form from

Methane Uptake by Inland Waters: Fact or Fiction?

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Inland waters are widely known as net emitters of methane (CH4) to the atmosphere, contributing ∼15% of global CH4 emissions. CH4 is produced by anaerobic methanogens in aquatic sediments, but net CH4 emissions at the water–air interface are modulated by CH4 oxidation by methanotrophs in the water column.

Characterizing Permafrost Distribution Along the Hudson Bay Railway Using Temperature‐Calibrated Electrical Resistivity Tomography

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract As the climate warms, understanding permafrost distribution along linear infrastructure is a key aspect of assessing, mitigating, and adapting to the risks associated with permafrost thaw. Electrical resistivity tomography (ERT) is becoming an increasingly common tool for evaluating permafrost distribution at the infrastructure scale.

Remote sensing of drained thermokarst lake basin successions [PDF]

open access: yes, 2018
Thermokarst lakes are important factors for permafrost landscape dynamics and carbon cycling. Thermokarst lake cover is particularly high in Arctic lowlands with ice-rich permafrost.

Rapid development of thermokarst lakes and driving factors along a highway in Northeast China (2000–2020)

open access: yesResearch in Cold and Arid Regions
In the northern Da Xing'anling Mountains of Northeast China, thermokarst lakes have undergone significant changes. These changes are particularly evident along the Highway X302, which stretches from Yakeshi in the south to Yitulihe in the north, across ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, Volume 55, Issue 4, Page 1073-1101, October 2026.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Permafrost Detachment Slides: A Distinct High‐Magnitude Permafrost Mass Wasting Process

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Warming permafrost is destabilizing landscapes, intensifying thaw‐driven mass wasting and giving rise to novel landslide forms. We characterize two recent (2017 and 2018), deep‐seated translational failures that we term Permafrost Detachment Slides (PDSs), which rapidly translocated 4.5 and 18 × 106 m3 of frozen material into downstream ...

n-Alkane Characteristics of Thawed Permafrost Deposits Below a Thermokarst Lake on Bykovsky Peninsula, Northeastern Siberia

open access: yesFrontiers in Environmental Science, 2020
Rapid permafrost thaw by thermokarst mobilizes previously frozen organic matter (OM) down to tens of meters deep within decades to centuries, leading to microbial degradation and greenhouse gas release. Late Pleistocene ice-rich Yedoma deposits that thaw
