Thermokarst lake monitoring on the Bykovsky Peninsula using high-resolution remote sensing data [PDF]

, 2018
Thermokarst lakes are a characteristic element of arctic permafrost regions and an indicator for their rapid landscape changes. Assessing their dynamics contributes to the understanding of driving processes of change, to the evaluation of impacts on ...

Coastal permafrost landscape development since the Late Pleistocene in the western Laptev Sea, Siberia [PDF]

, 2011
The palaeoenvironmental development of the western Laptev Sea is understood primarily from investigations of exposed cliffs and surface sediment cores from the shelf.

A Decade of Post‐Fire Succession Amplifies the Effect of Wildfire on the Surface Radiation Balance and Permafrost Thaw in Subarctic Peatlands

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 124-142, January/March 2026.
ABSTRACT Increasing wildfire activity is driving permafrost thaw in subarctic peatlands across the southern Northwest Territories, but the key mechanisms and progression of thaw following fire remain poorly understood. In response, 10 years (2015–2024) of near‐continuous surface (four‐component radiation, wind, and snow) and subsurface measurements ...

Policy implications of warming permafrost [PDF]

Permafrost is perennially frozen ground occurring in about 24% of the exposed land surface in the Northern Hemisphere. The distribution of permafrost is controlled by air temperature and, to a lesser extent, by snow depth, vegetation, orientation to ...

A lake-centric geospatial database to guide research and inform management decisions in an Arctic watershed in northern Alaska experiencing climate and land-use changes [PDF]

, 2017
Lakes are dominant and diverse landscape features in the Arctic, but conventional land cover classification schemes typically map them as a single uniform class.

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

Organic carbon stored in a thermokarst affected landscape on Baldwin Peninsula, Alaska [PDF]

, 2018
As Arctic warming continues and permafrost degrades, more organic carbon (OC) will be decomposed in high northern latitudes. Still, uncertainties remain in the quality and quantity of OC stored in permafrost.

Long-term perspectives on terrestrial and aquatic carbon cycling from palaeolimnology [PDF]

, 2015
Lakes are active processors and collectors of carbon (C) and thus recognized as quantitatively important within the terrestrial C cycle. Better integration of palaeolimnology (lake sediment core analyses) with limnological or modelling approaches has the
