Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies (Ep ${E}_{p}$) in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipation at all altitudes from 30 to 110 km.

Drag‐Controlled Regime Transitions in the Eddy Saturation Mechanism of the Antarctic Circumpolar Current

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Eddy saturation—the weak sensitivity of Antarctic Circumpolar Current (ACC) transport to wind stress—is a fundamental feature of Southern Ocean dynamics, yet the processes that maintain this state remain debated. Previous studies have proposed different mechanisms, including adjustments of eddies and standing meanders, but the conditions under

Global Plasmaspheric Refilling Rates Inferred From Deep‐Learning Electron Density Reconstructions

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract As a key process in magnetosphere‐ionosphere coupling, plasmaspheric refilling is a long‐standing focus in space physics. In this study, we develop a global electron density (GEO‐NE) model based on a CNN‐Transformer architecture, and use the model to investigate plasmaspheric electron density refilling rates. Using global electron density maps

High‐ and Low‐Concentration Spiral Chlorophyll Bands Excited by Vortex Rossby Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract High‐concentration spiral chlorophyll bands (HSCBs) embedded in oceanic mesoscale eddies have recently been observed worldwide. They are considered to be the footprints of vortex Rossby waves (VRWs). Based on satellite observations and drifter data, we identified additional low‐concentration spiral chlorophyll bands (LSCBs).

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...
