Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow

by Lei Zhou 28 September 201826 October 2022

Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.
