Oceanic mesoscale eddies are commonly assumed to act as coherent structures that trap and transport water masses over long distances. However, recent Lagrangian studies suggest that long-lived coherent structures in the ocean are much more limited than implied by Eulerian eddy boundaries. In this study, surface drift...

Utilizing two-dimensional sea level anomalies from the Surface Water and Ocean Topography (SWOT) wide-swath altimeter, we conduct a global census of fine-scale eddies (with equivalent radii < 30 km) that are beyond the resolution capacity of traditional altimeters. We find that these eddies are concentrated in regions...
Mesoscale eddies in the Southern Ocean extend from the surface to the deep ocean and contribute to regional and global ocean heat budgets. However, sparse in situ observations have limited estimates of eddy meridional heat transport (EMHT) to the near surface, leaving deep-ocean processes poorly understood. Here we qua...
