Mesoscale Oceanographic Processes Drive the Seasonal Abundance of the Seabob Shrimp Xiphopenaeus spp. on the Eastern Brazilian Shelf

Fisheries Oceanography, EarlyView.
ABSTRACT The seabob shrimp (Xiphopenaeus spp.) is a primary fishery resource in Brazil, with considerable economic and social importance along the coast. While environmental drivers of its life cycle are well‐documented for southeastern and southern populations, the factors modulating populations in the Eastern Brazilian Shelf remain poorly understood,

Large eddy simulation of ocean mesoscale eddies

Mesoscale eddies produce lateral (2D) fluxes that need to be parameterized in eddy-permitting (1/4-degree) global ocean models due to insufficient horizontal resolution. Here, we systematically apply methods from the 3D LES community to parameterize lateral vorticity fluxes produced by mesoscale eddies leveraging an explicit filtering approach together

Recent Anomalously Warm Ocean Conditions and Changes in the Migration and Spawning Distribution of Chub Mackerel (Scomber japonicus) in the Western North Pacific

Fisheries Oceanography, EarlyView.
ABSTRACT Extreme ocean warming has become increasingly pronounced in the western North Pacific in recent years. Coincident with this, both the egg abundance and the catch per unit effort (CPUE) of chub mackerel (Scomber japonicus) in fisheries targeting southward‐migrating adults have decreased.

Temperature Structure Inversion of Mesoscale Eddies in the South China Sea Based on Deep Learning

Journal of Marine Science and Engineering
Mesoscale eddies are common in global oceans, playing crucial roles in ocean dynamics, ocean circulation, and heat transport, and their vertical structures can affect the water layers from tens to thousands of meters.

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Mesoscale eddies inhibit intensification of the Subantarctic Front under global warming

Environmental Research Letters
Oceanic mesoscale eddies are important dynamical processes in the Southern Ocean. Using high-resolution (∼0.1° for the ocean) Community Earth System Model (CESM-HR) simulations under a high-carbon emission scenario, we investigate the role of mesoscale ...

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...

Sargassum spp. accumulation and transport by mesoscale eddies [PDF]

Ocean Science
The proliferation of pelagic Sargassum spp. (Sargassum) in the tropical Atlantic has significant ecological and socioeconomic impacts. While large-scale ocean circulation patterns influence the basin-scale distribution of Sargassum, the role of mesoscale

Shallow Cumulus Cloud Statistics in Real‐Case Large‐Eddy Simulations and Their Dependence on Soil Moisture

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract The ability of weather and climate models to reproduce the statistical properties of shallow cumulus clouds (SCCs) is critical for representing boundary‐layer transport, cloud cover, and cloud‐radiative effects. This study investigates statistical properties of SCC ensembles using the Icosahedral Nonhydrostatic model in large‐eddy simulation ...

Basin‐Scale Marine Heatwave Types in the Gulf of Mexico: Wind–Humidity Controls on Latent Heat‐Loss Suppression and Ocean‐State Modulation of Vertical Thermal Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) in the Gulf of Mexico (GoM) have become more frequent and intense, yet the mechanisms governing basin‐scale events remain incompletely understood. EOF–k‐means clustering of event‐mean sea surface temperature anomalies (SSTA) during 1982–2024 identifies four recurrent, seasonally dependent spatial regimes: two stronger ...
