Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract In the oligotrophic ocean, nutrient distribution plays a key role in controlling primary production via upward fluxes. In spring 2023, the BioSWOT‐Med cruise investigated how fine‐scale ocean dynamics influence nutrient availability in the Mediterranean Sea.

Hidden Fine‐Scale Transport Pathways and Biological Connectivity Revealed by SWOT
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Oceanic currents redistribute nutrients, phytoplankton, and other biogenic materials, fundamentally shaping marine biodiversity and ecosystem functioning. Yet, the topology of fine‐scale material transport remains poorly resolved due to limitations in high‐resolution flow observations.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The wide‐swath altimeter Surface Water and Ocean Topography (SWOT) provides unprecedented two‐dimensional sea‐level observations, whose ability to capture upper‐ocean dynamics requires assessment. The dynamically balanced signal and noise contributions in SWOT‐KaRIn Level‐3 (L3) sea level products are here originally quantified and contrasted ...

Linking Salinity and Precipitation Through Moisture Transport: A Study for the North Atlantic
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.Abstract Sea surface salinity (SSS) is a key indicator of the ocean–atmosphere freshwater balance and plays a central role in global moisture transport. This study investigates how extreme SSS anomalies in the North Atlantic (NATL) source region indicate atmospheric moisture pathways and precipitation in surrounding continental and island sink regions.

Machine Learned Equations for Vertical Mixing Coefficients in the Ocean Surface Boundary Layer
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Neural networks offer novel ways to parameterize unresolved ocean mixing but are challenging to interpret. Here, we derive compact equations that reproduce the behavior of neural networks trained on a second‐moment closure data set. The resulting interpretable expressions employed in a physics‐based first order closure scheme match neural ...

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Boundary‐layer winds strongly impact heavy rainfall through low‐level convergence, moisture transport, and vertical wind shear. Using high‐resolution observations from the 356‐m Shenzhen Meteorological Tower, together with ERA5 reanalysis and semi‐idealized numerical experiments, this study investigates the vertical structure and diurnal ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract This study investigates the response characteristics of oceanic pCO2 in different regions of the Northern South China Sea (NSCS) to tropical cyclone genesis frequency (TCF) on interannual timescale, and clarifies the response mechanisms. Results show that reduced Sea Surface Temperature (SST) induced by TCs suppresses pCO2 in the northwestern ...

Balanced to Unbalanced Motions at a Submesoscale Front and Energy Transfer From Eddy Splitting
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Submesoscale dynamics play a crucial role in energy redistribution in the upper ocean but remain challenging to observe due to their small spatial and temporal scales. We use ship‐based observations of an oceanic submesoscale front sampled at high resolution while repeatedly traversed to observe deformation and splitting of an embedded ...

Mixing at the Margins Drives Nitrate Delivery During Downwelling
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Wind‐driven coastal upwelling delivers nutrients to the surface waters and enhances primary productivity. In contrast, downwelling transports nutrient‐depleted water away from the surface and is usually presumed to decrease primary production. Here, we show that processes during downwelling can actually pump nutrients into previously nutrient ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract Decreases in anthropogenic aerosols will reduce fine particulate matter (PM2.5); however, meteorological feedbacks alter dust emissions, modifying air quality gains. We use eight Earth System Models from the Regional Aerosol Model Intercomparison Project (RAMIP) simulations to assess African climate and air quality responses to anthropogenic ...
