Investigating the Effect of Internal Waves on Vertical Ice Melting Rates

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Polar ice sheets are losing mass as a result of ocean‐driven melting processes and thus affecting global climate and sea level. Understanding the relevant dynamics and interactions at the ice‐ocean interface is crucial to developing more accurate sea‐level rise projections, but key ocean processes have not yet been considered in detail.

Interaction of Ocean Currents and Seamounts: Near‐Bottom Dynamics Around Atlantis II

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract This work investigates through a modeling exercise the interaction of a strong, surface current with isolated seamounts, focusing on the Gulf Stream and Atlantis II, one of the New England Seamounts. The roles of bathymetric details and model resolution are investigated with three simulations that consider realistic realizations of the ...

Topographic Scattering of Internal Waves in the Presence of a Steady Surface Current

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Wave–topography interaction is one of the primary mechanisms through which internal wave energy cascades to small length scales, eventually leading to turbulent diffusion and mixing in the oceans. Precise diffusivity parametrizations are crucial for modeling oceanic flows accurately.

Polar Front System Variability and Its Control on Export Rain Ratio Over the Past 800 ka: Implication for Atmospheric pCO2 Changes

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract Little is known about long‐term variability in the organic carbon to carbonate carbon export rain ratio, despite its key role in the global carbon cycle. Here, we reconstruct glacial‐interglacial changes in the sedimentary rain ratio over the Southern Ocean, using micropaleontological (coccoliths and foraminifera) and geochemical (CaCO3, Total

Tectonostratigraphic Evolution of the Guyana Basin: Implications for Sediment Routing and Slope Stability

Basin Research, Volume 38, Issue 2, March/April 2026.
Seismic profile across the Guyana Basin showing the main tectonostratigraphic units and an order‐of‐magnitude increase in sedimentation rates since the Middle Miocene corresponding with the onset of sedimentation dominated by mass transport deposits. ABSTRACT The Guyana Basin developed in an evolving tectonic setting, but a lack of subsurface data has ...

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

Fish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

‘Building the (Im)perfect Beast’: Strategies for Identifying Appropriate Spatial Stock Assessment Model Complexity From an International, Blinded High‐Resolution Simulation Experiment

Fish and Fisheries, Volume 27, Issue 2, Page 196-212, March 2026.
ABSTRACT Despite their potential to inform sustainable regional harvest and climate‐resilient fisheries management, spatial stock assessment models remain underused for management advice. To identify barriers that inhibit broader use of these methods, we conducted a blinded international simulation experiment mimicking real‐world stock assessment ...

Unraveling the Enrichment Mechanisms of Rare Earth Elements in Deep‐Sea Sediments: An Environmental Magnetic Perspective

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.
