Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow
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.

Carbonate Melting Enhances Mantle CO2 Fluxes in Old Ocean Basins
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.
