Brazil\'s Antarctica Territory |
Currently there are seven claimant nations who maintain a territorial claim on eight territories in Antarctica. These countries have tended to site their scientific observation and study facilities in Antarctica within their claimed territory.
It is sometimes stated that the Antarctic Treaty defers or suspends these claims. However, Article IV of the treaty, which deals with the issue of territorial claims, merely specifies that previously asserted claims are not affected by the treaty.
The Antarctic Treaty states that contracting to the treaty:
What the treaty does affect are new claims:
The Soviet Union and the United States both filed reservations against the restriction on new claims, and the United States and Russia assert their right to make claims in the future if they so choose. Brazil maintains the Comandante Ferraz (the Brazilian Antarctic Base) and has proposed a theory to delimiting territories using meridians, which would give territories to Argentina, Uruguay, Peru and Ecuador too.
In general, territorial claims below the 60° S parallel have only been recognised between those countries making claims in the area. However, claims are often indicated on maps of Antarctica - this does not signify de jure recognition.
All claim areas except Peter I Island (see below) are sectors, the borders of which are defined by degrees of longitude. In terms of latitude, the northern border of all sectors is the 60° S parallel which does not cut through any piece of land, continent or island, and is also the northern limit of the Antarctic Treaty. The southern border of all sectors collapses in one point, the South Pole. Only the Norwegian sector is an exception: the original claim of 1930 did not specify a northern or a southern limit, so that its territory is only defined by eastern and western limits.However, the Norwegian government has stated in 2003 that the northern extent of the Norwegian territory conforms to general practice by extending 12 nautical miles (22 km) from the shore.
