The Burdwood Bank, called Namuncurá in Argentina and other countries, is an undersea bank with a prominence of approximately 200 m (110 fathoms), part of the Scotia Arc projecting some 600 km (370 mi) from Cape Horn in the South Atlantic Ocean and located some 200 kilometres (120 mi) south of the Falkland Islands. Argentina claims economic rights over the whole of the bank, while the United Kingdom has designated about half of the bank as part of the Falklands Outer Economic Zone.
The Burdwood Bank is one of the four morphological features defined by the 200 m isobath off the coast of the Argentine — the other three being the Patagonian Shelf (Argentine Coastal Shelf), Isla de los Estados and the Falkland Islands. It forms a barrier to the northward flow of the Antarctic Circumpolar Current. The Bank itself (as defined by the 200 m isobath) is some 300 km (190 mi) from east to west and some 60 km (37 mi) from north to south. The channel to the west of the bank is about 80 km (50 mi) wide and 400 m (220 fathoms) deep while the channel to the east of the bank is 130 km (81 mi) wide and has a depth of up to 1,800 m (980 fathoms) deep.
