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 ...

Long-term spatiotemporal variability and driving mechanisms of tropospheric total column water vapor over Antarctica based on radiosonde, GNSS, and reanalysis data

Geo-spatial Information Science
Total column water vapor (TCWV) is a crucial indicator of atmospheric processes in the troposphere and a key driver of climate change. However, the severe environmental conditions in Antarctica constrain research on spatiotemporal variability and its ...

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 ...

Meteorological and surface radiation data observed at the Brazilian Antarctic station on King George Island

Data in Brief, 2019
The observational data described here was collected between 28 February 2011 and 30 November 2015. The data analysis and interpretation were published in the article “Surface radiation balance and weather conditions on a non-glaciated coastal area in the

State of Balance of the Ice Sheet in the Antarctic Peninsula [PDF]

Annals of Glaciology, 1982
Data from ice rises on the east coast of the Antarctic Peninsula can be interpreted as showing that the ice is thinning at rates of up 0.5 m a−1. However, a level line between two nunataks in Palmer Land showed no change in surface elevation over a period of 5 a.

Does Zonal Wave 3 Affect Total Antarctic Sea Ice Area?

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract While it is well‐established that Zonal Wave Three (ZW3) can drive regional expansion or contraction of Antarctic sea ice, it is unclear whether it has an effect on circumpolar total sea ice area (SIA). Here, we provide evidence to challenge previous studies' attribution of large overall Antarctic SIA decreases to ZW3.

Dark Land Surfaces Allow for Refugia That Could Support Photosynthetic Life on the Surface of Snowball Earth

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball Earth events, indicating that liquid‐water refugia existed somewhere on the surface. We examine the potential for refugia at the coldest time of a snowball event, before CO2 had risen and with high‐albedo ice on the frozen ocean, before it became darkened by dust deposition ...
