Congo River Freshwater Plume Carried Offshore by Ocean Eddies

A study using observations and a 3-km ocean model shows the Congo River releases about 40,000 cubic meters of freshwater per second, creating a plume that reaches roughly 800 km offshore; during the wet season, mesoscale eddies trap and transport low-salinity water hundreds of kilometers away, with a notable 49-day anticyclonic eddy in 2016 driving offshore transport and affecting regional circulation and marine ecosystems.
