(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

Antarctica

Population:

no indigenous inhabitants, but there are both permanent and
summer-only staffed research stations
note: 28 nations, all signatory to the Antarctic Treaty, operate
through their National Antarctic Program a number of seasonal-only
(summer) and year-round research stations on the continent and its
nearby islands south of 60 degrees south latitude (the region
covered by the Antarctic Treaty); these stations' population of
persons doing and supporting science or engaged in the management
and protection of the Antarctic region 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 onboard
research, are present in the waters of the treaty region; peak
summer (December-February) population - 4,219 total; Argentina 667,
Australia 200, Brazil 40, Bulgaria 15, Chile 237, China 70, Czech
Republic 20, Ecuador 26, Finland 20, France 100, France and Italy
