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 or an area of ocean. Several exploration
"firsts" were achieved in the early 20th century, but generally the
area saw little human activity. Following World War II, however, there was an
upsurge in scientific research on the continent. A number of countries have
set up a range of year-round and seasonal stations, camps, and refuges to
support scientific research in 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.

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; 21 of 28
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 -

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 -2,540
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 noncommercial 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%) (2005)
|
|||
Irrigated land:
|
|
|||
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
|
|||
Current Environment 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
|
|||
Population:
|
no
indigenous inhabitants, but there are both permanent and summer-only staffed
research stations note: 29 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); the population doing and supporting science or engaged in
the management and protection of the Antarctic region varies from
approximately 4,400 in summer to 1,100
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 - 4,490 total;

Antarctic
Treaty Summary - the Antarctic region is governed by a system known as the
Antarctic Treaty System; the system includes: 1. the Antarctic Treaty, signed
on 1 December 1959 and entered into force on 23 June 1961, which establishes
the legal framework for the management of Antarctica, 2. Recommendations and
Measures adopted at meetings of Antarctic Treaty countries, 3. The Convention
for the Conservation of Antarctic Seals (1972), 4. The Convention for the
Conservation of Antarctic Marine Living Resources (1980), and 5. The Protocol
on Environmental Protection to the Antarctic Treaty (1991); the 33rd
Antarctic Treaty Consultative Meeting was held in Punta del Este, Uruguay in
May 2010; at these periodic meetings, decisions are made by consensus (not by
vote) of all consultative member nations; by April 2010, there were 48 treaty
member nations: 28 consultative and 20 non-consultative; consultative
(decision-making) members include the seven nations that claim portions of Antarctica
as national territory (some claims overlap) and 21 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 years in
parentheses indicate when a consultative member-nation acceded to the Treaty
and when it was accepted as a consultative member, while no date indicates
the country was an original 1959 treaty signatory; claimant nations are -
Argentina, Australia, Chile, France, NZ, Norway, and the UK; nonclaimant
consultative nations are - Belgium, Brazil (1975/1983), Bulgaria (1978/1998),
China (1983/1985), Ecuador (1987/1990), Finland (1984/1989), Germany
(1979/1981), India (1983/1983), Italy (1981/1987), Japan, South Korea
(1986/1989), Netherlands (1967/1990), Peru (1981/1989), Poland (196 Article 1

weapons testing, is prohibited, but military personnel and equipment may be
used for scientific research or any other peaceful purpose; Article 2 -
freedom of scientific investigation and cooperation shall continue; Article 3
- free exchange of information and personnel, cooperation with the UN and
other international agencies; Article 4 - does not recognize, dispute, or
establish territorial claims and no new claims shall be asserted while the
treaty is in force; Article 5 - prohibits nuclear explosions or disposal of
radioactive wastes; Article 6 - includes under the treaty all land and ice
shelves south of 60 degrees 00 minutes south and reserves high seas rights; Article
7 - treaty-state observers have free access, including aerial observation, to
any area and may inspect all stations, installations, and equipment; advance
notice of all expeditions and of the introduction of military personnel must
be given; Article 8 - allows for jurisdiction over observers and scientists
by their own states; Article 9 - frequent consultative meetings take place
among member nations; Article 10 - treaty states will discourage activities
by any country in Antarctica that are contrary to the treaty; Article 11 -
disputes to be settled peacefully by the parties concerned or, ultimately, by
the ICJ; Articles 12, 13, 14 - deal with upholding, interpreting, and
amending the treaty among involved nations; other agreements - some 200
recommendations adopted at treaty consultative meetings and ratified by
governments; 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
six specific annexes: 1) environmental impact assessment, 2) conservation of
Antarctic fauna and flora, 3) waste disposal and waste management, 4) prevention
of marine pollution, 5) area protection and management and 6) liability
arising from environmental emergencies; it prohibits all activities relating
to mineral resources except scientific research; a permanent Antarctic Treaty
Secretariat was established in 2004 in Buenos Aires, Argentina

Legal system:
|
Antarctica
is administered through annual meetings - known as Antarctic Treaty
Consultative Meetings - which include consultative member nations,
non-consultative member nations, observer organizations, and expert
organizations; 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; more generally, access to the Antarctic Treaty
area, that is to all areas between 60 and 90 degrees south latitude, is
subject to a number of relevant legal instruments and authorization
procedures adopted by the states party to the Antarctic Treaty; note - US
law, including certain criminal offenses by or against US nationals, such as
murder, may apply extraterritorially; 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; telephone: (703) 292-8030, or visit its website at

Scientific
undertakings rather than commercial pursuits are the predominate human
activity in Antarctica. Fishing off the coast and
tourism, both based abroad, account for Antarctica's limited economic activity.
Antarctic fisheries, targeting three main species - Patagonian and Antarctic
toothfish (Dissostichus eleginoides and D. mawsoni), mackerel icefish
(Champsocephalus gunnari), and krill (Euphausia superba) - reported landing
141,147 metric tons in 2008-09 (1 July - 30 June). (Estimated fishing is from
the area covered by the Convention on the Conservation of Antarctic Marine
Living Resources (CCAMLR), which extends slightly beyond the Antarctic Treaty
area.) Unregulated fishing, particularly of Patagonian toothfish (also known
as Chilean sea bass), is a serious problem. The CCAMLR determines the
recommended catch limits for marine species. A total of 37,858 tourists
visited the Antarctic Treaty area in the 2008-09 Antarctic summer, down from
the 46,265 visitors in 2007-2008 (estimates provided to the Antarctic Treaty
by the International Association of Antarctica Tour Operators (IAATO); this
does not include passengers on overflights). Nearly all of them were
passengers on commercial (nongovernmental) ships and several yachts that make
trips during the summer.
