First Derivations of Air‐Sea CO2 Fluxes in the Central Mediterranean and Possible Impact of the 2022–2023 Marine Heatwave

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Marginal seas significantly impact the global carbon cycle. However, current knowledge on the role of marginal seas is limited, and only a few in situ data sets on air‐sea CO2 exchange are available. This study presents the first direct measurements of CO2 partial pressure (pCO2 ${\text{CO}}_{2}$) and derived air‐sea CO2 ${\text{CO}}_{2}$ flux

Thresholds of Wave Forcing: Implications for Atoll Reef Dynamics Under Sea Level Rise

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract We investigate the response of shallow reef flow to tidal variability and wave exposure during a 4‐month field campaign in southern Huvadhu Atoll, Maldives. Incident waves breaking on steep fore reefs and reef crests generate a setup proportional to offshore wave height that drives a cross‐reef flow. We emphasize a critical threshold—where the

Standing Meanders of the Antarctic Circumpolar Current: Evidence for Ridge‐Controlled Eddy Saturation

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The standing meanders of the Antarctic Circumpolar Current are key sites of mixing and meridional transport in the Southern Ocean, but their long‐term variability and trends remain poorly understood. Here, we investigate the Pacific‐Antarctic Ridge meander using satellite altimetry data from 1993 to 2023.

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.
