clude 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

Elevation extremes:
lowest point: Bentley Subglacial Trench -2,555 m
highest point: Vinson Massif 4,897 m
note: the lowest known land point in Antarctica is hidden in the
Bentley Subglacial Trench; at its surface is the deepest ice yet
discovered and the world's lowest elevation not under seawater

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

Land use:
arable land: 0%
permanent crops: 0%
other: 100% (ice 98%, barren rock 2%) (2001)

Irrigated land:
0 sq km

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; large icebergs may
calve from ice shelf

Environment - current issues:
in 1998, NASA satellite data showed that the antarctic ozone hole
was the largest on record, covering 27 million square kilometers;
researchers in 1997 found that increased ultraviolet light passing
through the hole damages the DNA of icefish, an antarctic fish
lacking hemoglobin; ozone depletion earlier was shown to harm
one-celled antarctic marine plants; in 2002, significant areas of
ice shelves disintegrated in response to regional warming

Geography - note:
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; mostly
uninhabitable

People Antarctica

Population:
no indigenous inhabitants, but there are both permanent and
summer-only staffed research stations
note: 26 nations, all signatory to the Antarctic Treaty, operate
seasonal (summer) and year-round research stations on the continent
and in its surrounding oceans; the population of persons doing and
supporting science o
