Antarctic Bottom Water Warming, Freshening, and Contraction in the Eastern Bellingshausen Basin

Geophysical Research Letters
Antarctic Bottom Water has been warming in recent decades throughout most of the oceans and freshening in regions close to its Indian and Pacific sector sources. We assess warming rates on isobars in the eastern Pacific sector of the Southern Ocean using

Viral Communities in the Global Deep Ocean Conveyor Belt Assessed by Targeted Viromics

Frontiers in Microbiology, 2019
Viruses are an abundant, diverse and dynamic component of marine and terrestrial ecosystems. In the ocean, viruses play a key role in the biogeochemical cycles and controlling microbial abundance, diversity and evolution.

Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

Land Degradation &Development, Volume 37, Issue 4, Page 1330-1352, 28 February 2026.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

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.

Observed water-mass characteristics and circulation off Prydz Bay, East Antarctica

Frontiers in Marine Science
Circulation and water masses in the greater Prydz Bay region were surveyed in the austral summer 2021 (January-March) during the ‘Trends in Euphausiids off Mawson, Predators and Oceanography’ (TEMPO) experiment, and are described in this paper.

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

Spatial Variability of the Hydrochemical Structure in Bottom Gravity Current in the Vema Fracture Zone

Russian Journal of Earth Sciences
The Vema Fracture Zone is located in the North Atlantic Ridge and extends along 11°N from 38 to 46°W. It is the main pathway for the spreading of Antarctic Bottom Water to the Northeast Atlantic.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.
