Impact of Model Resolution on Antarctic Bottom Water Representation in Coupled Climate Models

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Antarctic Bottom Water (AABW) formation plays a crucial role in the climate system by driving the lower branch of the global overturning circulation, redistributing heat and salt, storing anthropogenic carbon dioxide, and delivering oxygen to the deep ocean.

Circumpolar Effects of a Velocity‐Restoring Scheme for Antarctic Fast Ice on Shelf Waters and Ice Shelf Melt Simulated by NEMO4‐SI3

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Dense water formation in the Southern Ocean plays a key role in the global ocean overturning circulation, affecting the distribution of heat, carbon, oxygen, and nutrients. Fast ice stays immobile while blocking sea ice flow, favoring the opening of coastal polynyas, where intense air‐sea exchanges drive sea ice production and ocean ...

Europium in plagioclase-hosted melt inclusions reveals mantle melting modulates oxygen fugacity

Nature Communications
To gain insights into the composition and heterogeneity of Earth’s interior, the partial pressure of oxygen (oxygen fugacity, or fO2) in igneous rocks is characterized. A surprising observation is that relative to reference buffers, fO2s of mantle melts (

Reassessing the Role of the Antarctic Slope Current in Poleward Ocean Heat Transport

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The Antarctic Slope Current (ASC) is often considered a barrier to the poleward transport of Circumpolar Deep Water (CDW), yet its vast extent has hindered circumpolar analysis of this relationship. Here, we use a high‐resolution global ocean‐sea ice model that resolves the slope current to assess the link between variability in the ASC and ...

Short‐Wavelength Seafloor Topography From SWOT Marine‐Gravity Products Using a Transformer U‐Net With Hybrid Loss

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Classical satellite altimetry has limited sensitivity to seafloor topography at wavelengths shorter than about 150 km, leaving short‐wavelength structure poorly constrained away from ship tracks. The Surface Water and Ocean Topography (SWOT) mission improves gravity recovery at these scales.

Simulated Ocean Oxygen Under Miocene Boundary Conditions

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a warm interval with atmospheric CO2 ${\text{CO}}_{2}$ comparable to end‐of‐21st‐century projections under intermediate emission scenarios. Proxy records indicate the Oxygen Minimum Zone (OMZ) in the Eastern Tropical Pacific (ETP) was small or non‐existent during the MCO, expanding only when

Tracking the impact of bottom trawling on benthic habitat status

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Bottom trawling is the most widespread physical disturbance to marine benthic habitats, yet broadscale assessments of its impact remain limited. We developed a quantitative framework to evaluate trawling effects on benthic habitats at broad spatial scales based on the sentinels of seabed (SoS) indicator.

Seasonal and Diel Acoustic Occurrence of Sei Whales in Oregon, USA

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The behavior, distribution, and life history of sei whales (Balaenoptera borealis) are largely unknown in the North Pacific. We analyzed data from three bottom‐mounted acoustic recorders deployed 25 (shelf; depth = 300 m), 45 (slope; depth = 630 m), and 65 (abyssal; depth = 2860 m) nautical miles off of Newport, Oregon, USA that recorded ...

Abyssal echinoderm’s bioluminescence

, 2018
Virtually unknown the abyssal floor (from 2000 to 6000m deep) represents the vastest biotope on Earth (about 50% of the planet surface) and it is quite recently that a systematic exploration was conducted by one international consortium called CeDEMar ...

Utopia Remembers: The Soviet Past in the Imagined Communist Future

The Russian Review, Volume 85, Issue 4, Page 478-494, October 2026.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.
