Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract In the Ross Sea, sea‐ice processes such as coastal polynya formation and fast‐ice breakouts are often driven by strong winds associated with storms. In this study, a storm index derived from air pressure and air temperature anomalies observed at 13 weather stations in the Ross Sea region was used to investigate storm behavior between 1964 and ...

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.

Two Decades of Ross and Weddell Gyre Variability From Observations
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Weddell and Ross Gyres influence climate‐relevant processes including poleward heat transport, nutrient upwelling and carbon sequestration. However, long‐term tracking of changes to their circulation is limited by the sparsity of observations characteristic of the region.

Stratospheric Ozone Depletion Causes Southern Ocean Surface Cooling
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Stratospheric ozone depletion strongly influences Southern Ocean climate change. Using coupled climate model simulations, we quantify the transient effect of stratospheric ozone depletion on sea surface temperature (SST) over the Southern Ocean from 1982 to 2005.

Spatial Heterogeneity of Atlantic Water Upward Heat Flux in the Eurasian Basin Revealed by MOSAiC
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Atlantic Water (AW) is the main oceanic heat source in the Arctic and a key driver of sea ice retreat. Based on Multidisciplinary drifting Observatory for the Study of Arctic Climate microstructure data from the Eurasian Basin, we examined the spatial heterogeneity of AW upward heat flux.

The Observed Circumpolar Decline of Antarctic Bottom Water Volume
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Antarctic Bottom Water (AABW) formation is a key component of the global overturning circulation, ventilating the abyssal ocean and sequestering heat and carbon. Using a new reconstruction from the SatGEM‐2 monthly‐varying gravest empirical mode climatology, a continuous, observation‐driven circumpolar record of AABW variability is presented ...

Quantification of Heat and Salt Budgets in the Western Ross Ice Shelf Cavity and Polynya System
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The Ross Ice Shelf Polynya (RISP) is one of the primary production sites of the High Salinity Shelf Water (HSSW), the precursor of Antarctic Bottom Water (AABW) that drives the lower limb of global meridional overturning circulation. Utilizing a multi‐platform historical data set gathered over the western Ross Sea continental shelf, this study

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 ...
