The Caribbean Through-Flow is an important conduit between the North Atlantic Subtropical Gyre and the upper branch of the Atlantic Meridional Overturning circulation. Gradone et al. used observations collected during a series of consecutive 90-days glider transects during summer 2024. Their results show a significant decline in the magnitude of the zonal transport (by about 50%) which is attributed to a shift in dynamics from geostrophic balance to increased mesoscale activity. They provide an important insight into how ocean gliders in combination with other data streams help to further understand mesoscale circulation and quantify the contributions of eddies to transport in this understudied region of the Caribbean.
