A Strictly Geostrophic Product of Sea‐Surface Velocities From the SWOT Fast‐Sampling Phase
Abstract While geostrophy remains the simplest and most practical balance to extract velocity information from sea‐surface height anomaly (SSHa), confusions remain within the oceanographic community to what extent this balance can be applied to altimetric observations with the launch of the Surface Water and Ocean Topography (SWOT) satellite. Given the

Enhanced Tidal Mixing Strengthened and Stabilized the AMOC During the Bølling–Allerød
Abstract Proxy records indicate a robust Atlantic Meridional Overturning Circulation (AMOC) during the Bølling–Allerød (BA) interstadial, despite substantial meltwater discharge. Using ocean circulation simulations, we demonstrate that enhanced tidal mixing, sustained by lower‐than‐modern sea levels, significantly strengthens the BA AMOC and increases ...

FloeNet: A Mass‐Conserving Global Sea Ice Emulator That Generalizes Across Climates
Abstract We introduce FloeNet, a graph neural network trained to emulate the Geophysical Fluid Dynamics Laboratory global sea ice model, SIS2. FloeNet is a mass‐conserving model, emulating 6‐hr mass and area budget tendencies related to sea ice and snow‐on‐sea‐ice growth, melt, and advection.

Abstract In the Ross Sea, sea‐ice processes such as coastal polynya formation and fast‐ice breakouts are often driven by strong winds associated with storms. In this study, a storm index derived from air pressure and air temperature anomalies observed at 13 weather stations in the Ross Sea region was used to investigate storm behavior between 1964 and ...

Two Decades of Ross and Weddell Gyre Variability From Observations
Abstract The Weddell and Ross Gyres influence climate‐relevant processes including poleward heat transport, nutrient upwelling and carbon sequestration. However, long‐term tracking of changes to their circulation is limited by the sparsity of observations characteristic of the region.

Observed Multi‐Decadal Acceleration of Globally Averaged Abyssal Ocean Warming
Abstract Given sparse historical data in the deep and abyssal ocean, previously only multi‐decadal temperature trends have been estimated from observations there on a global scale. Full‐depth CTD sampling started circa 1970, with the first decadal global ship‐based survey occupied in the 1990s, and the first regional pilot array of Deep Argo floats ...
