The Bayelva high Arctic permafrost long-term observation site: an opportunity for joint international research on permafrost, atmosphere, ecology and snow [PDF]

, 1997
At present, the Arctic climate is changing much more rapidly than the rest of the globe, and yet observational data available in the region is poor.

Changes of hydrothermal structure of Austre Grønfjordbreen and Fridtjovbreen Glaciers in Svalbard

Лëд и снег, 2015
The results of ground-based RES studies (20 MHz) at the Austre Grønfjordbreen and Fridtjovbreen glaciers on Nordenskiöld Land, Svalbard, spring 2010–2012, were compared with previous airborne RES data (620 MHz) of 1979 to understand the hydrothermal ...

Stable Bacterial Cores and Patchy Eukaryotic Communities Shape the Summer Microbiomes of Patagonian Fjord Ecosystems Across Spatial, Functional and Temporal Gradients

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Our study shows that microbial community diversity in Patagonian fjords varies with glacial influence and salinity, with a widespread bacterial core but a patchier eukaryotic core. Distinct co‐occurrence networks and marked short‐term community shifts occur in water‑ versus land‐terminating glacier fjords, underscoring meltwater influence in this ...

Responses of Boundary Layer Cloud Structure and Particle Budget to Aerosol Sources During Arctic Marine Cold‐Air Outbreaks

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Marine cold‐air outbreaks (MCAOs) strongly modulate Arctic air‐sea exchange, yet their mixed‐phase clouds remain difficult to represent in Earth system models. We simulate an MCAO case using Lagrangian large‐eddy simulations that couple double‐moment microphysics with prognostic aerosol and ice formation parameterizations. We then apply a self‐

Quantifying Black Carbon Mixing State Heterogeneity Using a Machine Learning Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract The climate impact of black carbon (BC) is strongly sensitive to the mass ratio of non‐BC coatings to BC (RBC). However, current global climate models (GCMs) typically assume a uniform composition within individual BC‐containing particle populations, neglecting the significant particle‐to‐particle RBC heterogeneity. To address this, we train a
