The Patagonian (sometimes referred to as Argentine) [1]Shelf is part of the South American continental shelf belonging to the Argentine Sea on the Atlantic seaboard, south of about 35°S.
Various authorities quote different dimensions of the shelf, depending on how they define its limits.
[2][3] The shelf itself can be divided into a 100 km (62 mi) band where the seabed slopes at about 1 m/km then a wide plain (250 to 450 km (160 to 280 mi) wide) where the seabed slopes gently to 200 m (660 ft) isobath.
[1] The Falklands Trough separates the Patagonian Shelf from the Scotia Arc.
