An undersea plateau with a maximum depth of 200 metres, situated approximately 150 km east of the Isla de los Estados (Staten Island) and about 160 km south of the Falkland Islands (Malvinas) archipelago. Noteworthy are seabed fauna assemblages which include endemic species. Fish of commercial value, such as southern blue whiting, Patagonian toothfish, and Falkland sprat breed in waters that surround the bank.


Conservation Status


Biogeographical Region

Temperate seas of South America. Magellanic Province. Ecoregion: Malvinas / Falklands.


28.000 km2

Typs of Habitats

Undersea plateau. Oceanic and shelf pelagic and benthic environments.

Species Richness

Outstanding richness of benthic invertebrates, (some of them reported as endemic and vulnerable species) among them crustaceans, molluscs, 60 cold water coral species, hydrocorals, cnidaria and 30 sponge species. At least 18 seabird and marine mammal species forage or migrate in the area.

Main Uses

Some industrial fishing for Patagonian toothfish. Area of interest for the potential of its undersea oil fields.


Real direct threats are unknown. Ultimately, the start up of bottom trawling and oil drilling activites affecting the seabed and subsoil may have considerable impact on benthic communities.

Level of Protection

This area includes the "Namuncurá – Burdwood Bank" Marine Protected Area. There is a zone of 1,800 km2 totally and permanently closed to fishing.
