Scientific DataRetrogressive Thaw Slumps (RTS) are widespread mass-wasting hillslope failures triggered by thawing permafrost. While regional studies have provided insights into the spatial distribution and dynamics of RTS, a consistent and unbiased quantification and ...

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 11, November 2026.Abstract Open bedrock fractures are common features in unstable rock slopes and alter subsurface thermal conditions of fractured rock masses through convective air ventilation and atmospheric exchange. These processes are particularly relevant in cold mountain environments, where variations in ground temperature affect rock mass stability and may allow

Scientific ReportsThe presence of ice-layers in the subgrade soils makes the hydrothermal state of road subgrade built in island permafrost regions more susceptible to external environmental influences.

Petagram‐Scale Dissolved Organic Carbon Stocks in Alaskan Permafrost Soils
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The pan‐Arctic permafrost region hosts vast amounts of soil organic carbon, a pool increasingly susceptible to climate‐driven changes. Dissolved organic carbon (DOC) is a key component of this carbon pool. However, its stocks and fluxes remain poorly understood due to limited measurements and challenges of tracking subsurface fluxes across ...

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The sequence of events in the global carbon cycle during deglaciations is not entirely understood. Here, we analyze mean ocean δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O in an updated compilation of foraminiferal stable isotope data comprising 902 time series from 381 sediment cores, with individual records covering intervals within the ...

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract How the convergent strain between the India Plate and the Tarim basin is partitioned by active faults and off‐fault deformation in southwestern Tibet is poorly understood due to limited knowledge of strain localisation and fault kinematics. In this study, we derive high‐resolution velocity fields for the southwestern Tibetan Plateau using both

, 1972 The upsurge of public interest in northern regions in recent years has brought the name `permafrost' into the market place. The proposed construction of pipelines for gas and oil from the Arctic Coast to southern Canada is now generally known to be complicated by the existence of permafrost along considerable parts of the routes that may be followed ...

Sandy Turbidity Current Acts as a Rusty Carbon Pump at the Shelf Edge
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Sandy turbidity currents (STCs) efficiently sequester organic carbon (OC) through rapid burial. Yet our understanding of OC preservation within STC deposits remains far less constrained, especially considering STC deposits as an inferred major sink for iron‐bound OC (Fe‐OC), a long‐term stabilized form of OC.
