Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

Glacial Expansion of Deoxygenation in the Arabian Sea
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The mechanisms by which ongoing climate change influences ocean Oxygen Minimum Zones (OMZs) are insufficiently understood, making it essential to examine their long‐term variations under substantial climatic forcing. Here, we present the first planktic foraminifera iodine‐to‐calcium records in two Arabian Sea sediment cores: one located within

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The ice shelves in the Amundsen Sea are being melted rapidly by warm Circumpolar Deep Water (CDW), causing sea‐level rise. Ice‐shelf melt variability is controlled by the speed of a shelf‐break undercurrent which transports CDW onto the continental shelf. We study decadal variability of the undercurrent and ice‐shelf melting using new regional

Southern Ocean Sulfate Aerosol Sources Quantified From Sulfur Isotopes in Antarctic Ice Cores
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The Southern Ocean has emerged as a key region for constraining aerosol‐climate interactions due to its relatively low anthropogenic influence. Sulfate is an important aerosol over the Southern Ocean, and models suggest dimethyl sulfide (DMS) is the largest source of sulfate during summer.

The Zonal Wave‐3 Mode Impacts Antarctic Dense Water Formation
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract At the Antarctic margins, dense water masses form as sea ice develops, driving the Antarctic branch of the global meridional overturning circulation. Previous studies found that large‐scale climate modes such as the Southern Annular Mode and El Niño Southern do not fully account for the interannual variability of dense water formation.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Global ocean circulation regulates climate and has undergone significant changes over the Cenozoic. Today, the Atlantic Meridional Overturning Circulation (AMOC) is driven by North Atlantic Deep Water (NADW) formation and Southern Ocean upwelling.

Future Shoaling of the AMOC and Its Impact on Oceanic Heat Transport to the Subpolar North Atlantic
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The Atlantic Meridional Overturning Circulation (AMOC) carries oceanic heat northward to the subpolar North Atlantic (SPNA), where the surface water cools and sinks to the deep ocean. According to a large‐ensemble simulation under a medium‐to‐high emission scenario, the surface cooling and oceanic heat convergence in the SPNA may decrease to ...
