C and N Isotopic Fractionation Along Permafrost Profiles: A Theoretical Framework and Empirical Tests Across the Arctic

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Anticipating the decomposition of permafrost organic matter (OM) following thaw is critical for improving projections of climate‐carbon feedbacks. Stable carbon (C) and nitrogen (N) isotope profiles provide integrated records of the environmental and biogeochemical processes that shaped OM during its accumulation and may therefore improve our ...

Enhancing the Advanced Lake Biogeochemistry Model for Application to Thermokarst Lakes on Qinghai‐Tibet Plateau

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Thermokarst lakes on Qinghai‐Tibet Plateau (QTP) are significant sources of greenhouse gas emissions, yet the underlying governing processes remain poorly understood. This study refines the Advanced Lake Biogeochemistry Model (ALBM) to characterize the unique environmental and biogeochemical processes of QTP thermokarst lakes. Key improvements

Refined Modeling of Arctic Circumpolar Building Stock Increases Estimated Mid‐Century Permafrost Degradation Damages

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Near‐surface permafrost degradation has the potential to damage infrastructure needed to sustain Arctic communities, but risk assessments remain highly uncertain due to a limited representation of the Arctic circumpolar building stock. With deep learning building footprint detection and building occupancy classification models, we expand the ...

Evaporation From Soil and Thermokarst Lakes Contribute More to Local Precipitation Than Plant Transpiration in Permafrost Regions of the Central Qinghai—Tibet Plateau

Water Resources Research
Permafrost degradation on the Qinghai—Tibet Plateau (QTP) directly affects evapotranspiration and moisture recycling processes by changing the underlying land surface conditions.

Soil drying induces widespread productivity loss but unequal climate vulnerability among ecotypes of a foundational Arctic sedge

Functional Ecology, Volume 40, Issue 7, Page 2301-2317, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As temperatures increase in the Arctic, hydrological change may lead to local soil drying through altered snowpack, evapotranspiration and drainage due to permafrost thaw.

Past and present thermokarst lake dynamics in the Yedoma Ice Complex region of North-Eastern Yakutia [PDF]

, 2018
Thermokarst lakes are typical components of the yedoma-alas dominated relief in the coastal lowlands of North- Eastern Yakutia and formed as a result of thawing Late Pleistocene ice-rich Yedoma Ice Complex (IC) deposits.

Biogeochemical and hydrochemical parameters of sediment core PG2412 beneath thermokarst lake Goltsovoye Lake on the Bykovsky Pensinula, northeastern Siberia [PDF]

, 2020
These datasets describe a 31.5 m long sediment core taken from beneath thermokarst lake Goltsovoye Lake (71.74515 N, 129.30217 E) on the Bykovsky Peninsula, northeastern Siberia. The thermokarst lake was 510 cm deep.

Addressing Uncertainties in Climate–Ecosystem Feedbacks in the Arctic: Ten Priority Research Questions for Integrated Observation and Modeling

Ecological Research, Volume 41, Issue 4, July 2026.
Uncertainties exist in the biosphere–climate feedbacks in the Arctic. Remote and ground measurements play complementary roles in detecting possible changes. A critical next step is identification of key drivers of the global changes for future projections. ABSTRACT Positive biosphere–climate feedbacks are likely to amplify the Arctic warming, yet major

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

Frontiers 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

ASSESSMENT OF THE DYNAMICS OF THERMOKARST LAKES BASED ON THEIR MORPHOLOGICAL AFFILIATION [PDF]

Proceedings of the International conference “InterCarto/InterGIS”, 2017
We have proposed an approach to estimating the areal dynamics of thermokarst lakes. It takes into account the role of the main factors in the development of the lake thermokarst, one of the most common processes in the accumulative plains of Russian permafrost zone.
