Distinct El Niño Flavors and SAM Variability Modulate Surface Melt Over the Ross Ice Shelf

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Our study investigates how different flavors of El Niño, centered on the Eastern Pacific (EP) and Central Pacific (CP), and their interaction with the Southern Annular Mode (SAM) modulate surface melt events over the Ross Ice Shelf (RIS). Using satellite‐based melt observations, ERA5 reanalysis, high‐resolution regional model simulations, and ...

SWOT High‐Rate Raster Data Reveals Antarctic Ice Shelf Motion and Change in Response to Ocean and Ice Dynamics

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Three Decades of Glacial Changes on the Western Antarctic Peninsula Revealed by Historical Aerial and High‐Resolution Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic Peninsula has been climate‐sensitive since the mid‐20th century, but long‐term glacier mass balance data are scarce. This study uses historical aerial and high‐resolution satellite imagery to estimate mass changes on the western Antarctic Peninsula (66°S $66{}^{\circ}\mathrm{S}$–68°S $68{}^{\circ}\mathrm{S}$) from 1989 to 2020 ...

Mass Loss From Thwaites Glacier Continues Even Without Ocean Melting

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Pine Island and Thwaites glaciers dominate Antarctica's sea‐level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present‐day ocean conditions, perhaps linked to anthropogenic climate change, or are an ongoing response to historical natural climate anomalies.

Enhanced Tidal Mixing Strengthened and Stabilized the AMOC During the Bølling–Allerød

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Proxy records indicate a robust Atlantic Meridional Overturning Circulation (AMOC) during the Bølling–Allerød (BA) interstadial, despite substantial meltwater discharge. Using ocean circulation simulations, we demonstrate that enhanced tidal mixing, sustained by lower‐than‐modern sea levels, significantly strengthens the BA AMOC and increases ...
