Irreversible Transitions of the Ocean Circulation in Antarctic Ice‐Shelf Cavities

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Ice shelves fringing the Antarctic continent experience low or high basal melt rates depending on local shelf conditions, ocean circulation and intensity of ice‐sea‐air exchanges. Recent studies have uncovered potential cold‐to‐warm transitions in specific ice‐shelf cavities, which could lead to a dramatic increase in sea‐level rise.

Preferred Time Scales of Pacific Decadal Variability During the Last Millennium Related to Volcanic Activity

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pacific Decadal Variability (PDV) plays a significant role in modulating the global climate change on decadal time scale. Although various reconstructions of the PDV have been developed for the last millennium, preferred time scales of the PDV and mechanisms behind them remain unresolved. Here, we combine a δ18O‐based PDV index derived through

Lower Glacial Oxygen in the Eastern Equatorial Pacific Concentrated in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Oxygen in the global oceans has declined since the 1960s, including in the Eastern Equatorial Pacific (EEP). Reconstructions of EEP glacial oxygenation help advance understanding of current and projected ocean deoxygenation. Previous estimates of the glacial oxygen deficient zones (ODZs) in the upper EEP are poorly constrained. Here we include

Antarctic Meltwater Accelerates Southern Ocean Evolution Under Projected Atmospheric Warming

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Increasing basal meltwater from Antarctic ice shelves may impact the Southern Ocean properties that feed back on the rate of melting. We investigate this feedback in a high‐emissions scenario using an Earth‐system model with interactive ice‐shelf basal melting, an improvement on previous studies that did not have the capability to evolve melt ...

New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.
