Antarctica
Background:
|
Speculation over the existence of a
"southern land" was not confirmed until the early 1820s when British and
American commercial operators and British and Russian national expeditions
began exploring the Antarctic Peninsula region and other areas south of
the Antarctic Circle. Not until 1840 was it established that Antarctica
was indeed a continent and not just a group of islands. Several
exploration "firsts" were achieved in the early 20th century. 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. Seven have made territorial claims, but not all countries
recognize these claims. In order to form a legal framework for the
activities of nations on the continent, an Antarctic Treaty was negotiated
that neither denies nor gives recognition to existing territorial claims;
signed in 1959, it entered into force in 1961. |
Geographic coordinates:
|
90 00 S, 0
00 E |
Area - comparative:
|
slightly
less than 1.5 times the size of the US |
Coastline:
|
17,968 km
|
Maritime claims:
|
Australia,
Chile, and Argentina claim Exclusive Economic Zone (EEZ) rights or similar
over 200 nm extensions seaward from their continental claims, but like the
claims themselves, these zones are not accepted by other countries; 20 of
27 Antarctic consultative nations have made no claims to Antarctic
territory (although Russia and the US have reserved the right to do so)
and do not recognize the claims of the other nations; also see the
Disputes - international entry |
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 nearly 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 |
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) |
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 coming 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 |
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 on the continent and its nearby islands south of 60 degrees south
latitude (the region covered by the Antarctic Treaty) 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; summer
(January) population - 3,687 total; Argentina 302, Australia 201, Belgium

Antarctic Treaty Summary - the Antarctic
Treaty, signed on 1 December 1959 and entered into force on 23 June 1961,
establishes the legal framework for the management of Antarctica; the 26th
Antarctic Treaty Consultative Meeting was held in Madrid, Spain in June
2003; at these periodic meetings, decisions are made by consensus (not by
vote) of all consultative member nations; at the end of 2003, there were
45 treaty member nations: 27 consultative and 18 non-consultative;
consultative (decision-making) members include the seven nations that
claim portions of Antarctica as national territory (some claims overlap)
and 20 non-claimant nations; the US and Russia have reserved the right to
make claims; the US does not recognize the claims of others; Antarctica is
administered through meetings of the consultative member nations;
decisions from these meetings are carried out by these member nations
(with respect to their own nationals and operations) in accordance with
their own national laws; the year in parentheses indicates when an
acceding nation was accepted as a consultative member, while no date

were later incorporated into the Environmental Protocol; Convention for
the Conservation of Antarctic Seals (1972); Convention on the Conservation
of Antarctic Marine Living Resources (1980); a mineral resources agreement
was signed in 1988 but remains unratified; the Protocol on Environmental
Protection to the Antarctic Treaty was signed 4 October 1991 and entered
into force 14 January 1998; this agreement provides for the protection of
the Antarctic environment through five specific annexes: 1) environmental
impact assessment, 2) conservation of Antarctic fauna and flora, 3) waste
disposal and waste management, 4) prevention of marine pollution, and 5)
area protection and management; it prohibits all activities relating to
mineral resources except scientific research |
Legal system:
|
Antarctica is administered through
meetings of the consultative member nations; decisions from these meetings
are carried out by these member nations (with respect to their own
nationals and operations) in accordance with their own national laws; US
law, including certain criminal offenses by or against US nationals, such
as murder, may apply extra-territorially; some US laws directly apply to
Antarctica; for example, the Antarctic Conservation Act, 16 U.S.C. section
2401 et seq., provides civil and criminal penalties for the following
activities, unless authorized by regulation of statute: the taking of
native mammals or birds; the introduction of nonindigenous plants and
animals; entry into specially protected areas; the discharge or disposal
of pollutants; and the importation into the US of certain items from
Antarctica; violation of the Antarctic Conservation Act carries penalties
of up to $10,000 in fines and one year in prison; the National Science
Foundation and Department of Justice share enforcement responsibilities;
Public Law 95-541, the US Antarctic Conservation Act of 1978, as amended
in 1996, requires expeditions from the US to Antarctica to notify, in
advance, the Office of Oceans, Room 5805, Department of State, Washington,
DC 20520, which reports such plans to other nations as required by the
Antarctic Treaty; for more information, contact Permit Office, Office of
Polar Programs, National Science Foundation, Arlington, Virginia 22230;

Economy - overview:
|
Fishing off the coast and tourism, both
based abroad, account for the limited economic activity. Antarctic
fisheries in 2000-01 (1 July-30 June) reported landing 112,934 metric
tons. Unregulated fishing, particularly of Patagonian toothfish, is a
serious problem. The Convention on the Conservation of Antarctic Marine
Living Resources determines the recommended catch limits for marine
species. A total of 13,571 tourists visited in the 2002-03 antarctic
summer, up from the 11,588 who visited the previous year. Nearly all of
them were passengers on commercial (nongovernmental) ships and several
yachts that make trips during the summer. Most tourist trips last
approximately two weeks. |

Ports and harbors:
|
there are no developed ports and harbors
in Antarctica; most coastal stations have offshore anchorages, and
supplies are transferred from ship to shore by small boats, barges, and
helicopters; a few stations have a basic wharf facility; US coastal
stations include McMurdo (77 51 S, 166 40 E), Palmer (64 43 S, 64 03 W);
government use only except by permit (see Permit Office under "Legal
System"); all ships at port are subject to inspection in accordance with
Article 7, Antarctic Treaty; offshore anchorage is sparse and intermittent
|
Airports:
|
there are no developed public access
airports or landing facilities; 30 stations, operated by 16 national
governments party to the Antarctic Treaty, have restricted aircraft
landing facilities for either helicopters and/or fixed-wing aircraft;
commercial enterprises operate two additional aircraft landing facilities;
helicopter pads are available at 27 stations; runways at 15 locations are
gravel, sea-ice, blue-ice, or compacted snow suitable for landing wheeled,
fixed-wing aircraft; of these, 1 is greater than 3 km in length, 6 are
between 2 km and 3 km in length, 3 are between 1 km and 2 km in length, 3
are less than 1 km in length, and 2 are of unknown length; snow surface
skiways, limited to use by ski-equipped, fixed-wing aircraft, are
available at another 15 locations; of these, 4 are greater than 3 km in
length, 3 are between 2 km and 3 km in length, 2 are between 1 km and 2 km
in length, 2 are less than 1 km in length, and 4 are of unknown length;
aircraft landing facilities generally subject to severe restrictions and
limitations resulting from extreme seasonal and geographic conditions;
aircraft landing facilities do not meet ICAO standards; advance approval
from the respective governmental or nongovernmental operating organization
required for landing; landed aircraft are subject to inspection in
accordance with Article 7, Antarctic Treaty (2003 est.) |

Disputes - international:
|
Antarctic Treaty freezes claims (see
Antarctic Treaty Summary in Government type entry); sections (some
overlapping) claimed by Argentina, Australia, Chile, France, NZ, Norway,
and UK; the US and most other states do not recognize the territorial
claims of other states and have made no claims themselves (the US and
Russia reserve the right to do so); no claims have been made in the sector
between 90 degrees west and 150 degrees west; several states with land
claims in Antarctica have expressed their intention to submit data to the
UN Commission on the Limits of the Continental Shelf to extend their
continental shelf claims to adjoining undersea ridges |
