Introduction

   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.

                note: fifth-largest continent, following Asia, Africa,
                North America, and South America, but larger than
                Australia and the subcontinent of Europe

                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 - 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  lowest point: Bentley Subglacial Trench -2,555 m
     extremes:  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  iron ore, chromium, copper, gold, nickel, platinum and
    resources:  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%) (2005)

       Natural  katabatic (gravity-driven) winds blow coastward from
      hazards:  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 -  in 1998, NASA satellite data showed that the Antarctic
       current  ozone hole was the largest on record, covering 27
       issues:  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 -  the coldest, windiest, highest (on average), and driest
         note:  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

   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 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)

    Government  Antarctic Treaty Summary - the Antarctic Treaty, signed
         type:  on 1 December 1959 and entered into force on 23 June
                1961, establishes the legal framework for the
                management of Antarctica; the 28th Antarctic Treaty
                Consultative Meeting was held in Stockholm, Sweden in
                June 2005; at these periodic meetings, decisions are
                made by consensus (not by vote) of all consultative
                member nations; at the end of 2005, there were 45
                treaty member nations: 28 consultative and 17
                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 -

                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 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 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
                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
                their website at www.nsf.gov; 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

Economy

     Economy -  Fishing off the coast and tourism, both based abroad,
     overview:  account for Antarctica's limited economic activity.
                Antarctic fisheries in 2003-04 (1 July-30 June)
                reported landing 136,262 metric tons (estimated fishing
                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, is a serious problem. The CCAMLR
                determines the recommended catch limits for marine
                species. A total of 23,175 tourists visited in the
                2004-05 Antarctic summer, up from the 19,486 visitors
                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.

Transportation

     Airports:  20
                note: there are no developed public access airports or
                landing facilities; 28 stations or remote field
                locations, operated by 11 National Antarctic Programs
                from nations party to the Antarctic Treaty, have
                restricted aircraft landing facilities comprising a
                total of 11 runways and 22 skiways for fixed-wing
                aircraft; some stations have both runways and skiways;
                commercial enterprises operate two aircraft landing
                facilities at one station; helicopter pads are
                available at all 37 year-round and 15 seasonal stations
                operated by National Antarctic Programs; the 11 runways
                are suitable for wheeled, fixed-wing aircraft: three
                are gravel, four blue-ice, two sea-ice and two
                compacted snow; of these, five are 3 km in length, two
                are between 2 km and 3 km in length, three are between
                1 km and 2 km in length and one is less than 1 km in
                length; the 22 snow surface skiways are limited to use
                by ski-equipped, fixed-wing aircraft; of these, three
                are equal to or greater than 3 km in length, one is
                between 2 km and 3 km in length, nine are between 1 km
                and 2 km in length, five are less than 1 km in length,
                and four are of unknown or variable length; snow
                surface skiways are generally prepared and maintained
                during specific periods only and during summer; all
                aircraft landing facilities 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 using their
                facilities; landed aircraft are subject to inspection
                in accordance with Article 7, Antarctic Treaty;
                guidelines for the operation of aircraft near
                concentrations of birds in Antarctica were adopted in
                2004; relevant legal instruments and authorization
                procedures adopted by states party to the Antarctic
                Treaty regulating access to the Antarctic Treaty area,
                that is to all areas between 60 and 90 degrees of
                latitude South, have to be complied with (see
                information under "Legal System"); an Antarctic Flight
                Information Manual (AFIM) providing up-to-date details
                of Antarctic air facilities and procedures is
                maintained and published by the Council of Managers of
                National Antarctic Programs (2006)

                (2006)

     Ports and  there are no developed ports and harbors in Antarctica;
    terminals:  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), and 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; relevant legal instruments and
                authorization procedures adopted by the states parties
                to the Antarctic Treaty regulating access to the
                Antarctic Treaty area, to all areas between 60 and 90
                degrees of latitude south, have to be complied with
                (see "Legal System"); The Hydrographic Committee on
                Antarctica (HCA), a special hydrographic commission of
                International Hydrographic Organization (IHO), is
                responsible for hydrographic surveying and nautical
                charting matters in Antarctic Treaty area; it
                coordinates and facilitates provision of accurate and
                appropriate charts and other aids to navigation in
                support of safety of navigation in region; membership
                of HCA is open to any IHO Member State whose government
                has acceded to the Antarctic Treaty and which
                contributes resources and/or data to IHO Chart coverage
                of the area; members of HCA are Argentina, Australia,
                Chile, China, France, Germany, Greece, India, Italy,
                NZ, Norway, Russia, South Africa, Spain, and the UK
                (2005)

Military

    Military -  the Antarctic Treaty prohibits any measures of a
         note:  military nature, such as the establishment of military
                bases and fortifications, the carrying out of military
                maneuvers, or the testing of any type of weapon; it
                permits the use of military personnel or equipment for
                scientific research or for any other peaceful purposes

Transnational
Issues

    Disputes -  Antarctic Treaty freezes claims (see Antarctic Treaty
international:  Summary in government type entry); Argentina,
                Australia, Chile, France, NZ, Norway, and UK claim land
                and maritime sectors (some overlapping) for a large
                portion of the continent; the US and many other states
                do not recognize these territorial claims 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 territorial 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
