Some of the major rivers are the Paraná, Uruguay—which join to form the Río de la Plata, Paraguay, Salado, Negro, Santa Cruz, Pilcomayo, Bermejo and Colorado. These rivers are discharged into the Argentine Sea, the shallow area of the Atlantic Ocean over the Argentine Shelf, an unusually wide continental platform. Its waters are influenced by two major ocean currents: the warm Brazil Current and the cold Falklands Current.
