The Burdwood Bank, called Namuncurá in Argentina and other countries, is an undersea bank with a prominence of approximately 200 metres (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.
[2] The Burdwood Bank is one of the four morphological features defined by the 200 metre (110 fathom) 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.
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.
This in turn produced tsunami-like events that hit the Falkland Islands on its southern coast.
The species community on the bank is dominated by the small notothenids Patagonotothen guntheri and Patagonian toothfish.
