How Southern Ocean Currents Modulate Global Biogeochemical Cycles

by Susan Trumbore 14 January 202514 January 2025

Swirling currents called mesoscale eddies occupy about 22% of the ice-free Southern Ocean. Using data from drifting floats and satellites, scientists report the impact these eddies have on biogeochemical cycles.
