Which marginal sea lies off Argentina's Atlantic coast?

Which marginal sea lies off Argentina's Atlantic coast? The Argentine Sea is the marginal sea of the South Atlantic adjoining Argentina's eastern and southeastern coast.

It occupies the continental shelf from roughly the Río de la Plata estuary southward to Isla de los Estados, near Tierra del Fuego. Its shelf setting means it is comparatively shallow beside the much deeper Argentine Basin farther offshore. The sea also includes waters around the Falkland Islands within the broad Patagonian Shelf region.

The Argentine Sea is especially important biologically. Cold water from the Falkland Current arrives from the south, while the warm Brazil Current approaches from the north. Their meeting, together with shelf waters and river influence, helps support plankton, fish, seabirds, penguins, marine mammals and productive fisheries.

The name is relatively modern: it appears to have been coined by explorer Julius Popper and entered regional charts in the late nineteenth century. Do not confuse the Argentine Sea with the Scotia Sea, which lies farther south and east near the Drake Passage and Antarctica.
