tions do not recognize the territorial claims of other
nations and have made no claims themselves (the US reserves the
right to do so); no formal claims have been made in the sector
between 90 degrees west and 150 degrees west

Climate: severe low temperatures vary with latitude, elevation,
and distance from the ocean; East Antarctica is colder than West
Antarctica because of its higher elevation; Antarctic Peninsula has
the most moderate climate; higher temperatures occur in January
along the coast and average slightly below freezing

Terrain: about 98% thick continental ice sheet and 2% barren rock,
with average elevations between 2,000 and 4,000 meters; mountain
ranges up to about 5,000 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
lowest point: Indian Ocean 0 m
highest point: Vinson Massif 5,140 m

Natural resources: none presently exploited; iron ore, chromium,
copper, gold, nickel, platinum and other minerals, and coal and
hydrocarbons have been found in small, uncommercial quantities

Land use:
arable land: 0%
permanent crops: 0%
meadows and pastures: 0%
forest and woodland: 0%
other: 100% (ice 98%, barren rock 2%)

Irrigated land: 0 sq km

Environment:
current issues: in October 1991 it was reported that the ozone
shield, which protects the Earth's surface from harmful ultraviolet
radiation, had dwindled to the lowest level recorded over Antarctica
since 1975 when measurements were first taken
natural hazards: katabatic (gravity-driven) winds blow coastward
from the high interior; frequent blizzards form near the foot of the
plateau; cyclonic storms form over the ocean and move clockwise
along the coast; volcanism on Deception Island and isolated areas of
West Antarctica; other seismic activity rare and weak
international agreements: NA

Geographic note: the coldest, windiest, highest, 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; mostly uninhabitable
