Speculation over the existence of a "southern land" was not confirmed
until the early 1820s. Not until 1838 was it established that Antarctica
was indeed a continent and not just a group of islands. Following World
War II, there was an upsurge in scientific research on the continent.
A number of countries have set up year-round research stations on Antarctica.
Total Area of Antarctica is 14 million sq km. 280,000 sq km of which
are ice-free, 13.72 million sq km are ice-covered. East Antarctica is
colder than West Antarctica because of its higher elevation; The Antarctic
Peninsula has the most moderate climate; higher temperatures occur in
January along the coast and average slightly below freezing.
As the fifth-largest continent, about 98% of Antarctica is thick continental
ice sheet and 2% barren rock, with average elevations between 2,000 and
4,000 meters. Mountain ranges up to 5,140 meters, ice-free coastal areas
include parts of southern Victoria Land, Wilkes Land, the Antarctic Peninsula
area, and parts of Ross Island on McMurdo Sound; glaciers form ice shelves
along about half of the coastline, and floating ice shelves constitute
11% of the area of the continent.
Natural resources: iron ore, chromium, copper, gold, nickel, platinum
and other minerals, and coal and hydrocarbons have been found in small
uncommercial quantities; none presently exploited; krill, finfish, and
crab have been taken by commercial fisheries.
Geographically Antarctica is the coldest, windiest, highest (on average),
and driest continent. During summer, more solar radiation reaches the
surface at the South Pole than is received at the Equator in an equivalent
period making Antarctica mostly uninhabitable. There are no Indigenous
inhabitants.
The population of persons doing and supporting science on the continent
and its nearby islands varies from approximately 4,000 in summer to 1,000
in winter. In addition, approximately 1,000 personnel including ship's
crew and scientists doing on board research are present in the waters
of the treaty region.
