  Antarctica
      n 1: an extremely cold continent at the south pole almost
           entirely below the Antarctic Circle; covered by an ice cap
           up to 13,000 feet deep; "Antarctica is twice the size of
           Australia" [syn: Antarctica, Antarctic continent]

     Introduction 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 no
                                          other country recognizes 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.

                                 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

            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

                      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
                                          probably landed more fish than the
                                          regulated fishery, and allegedly
                                          illegal fishing in antarctic waters
                                          in 1998 resulted in the seizure (by
                                          France and Australia) of at least
                                          eight fishing ships. The Convention
                                          on the Conservation of Antarctic
                                          Marine Living Resources determines
                                          the recommended catch limits for
                                          marine species. A total of 12,248
                                          tourists visited in the 2000-01
                                          antarctic summer, down from the
                                          14,762 who visited the previous
                                          year. Nearly all of them were
                                          passengers on 21 commercial
                                          (nongovernmental) ships and several
                                          yachts that made trips during the
                                          summer. Most tourist trips lasted
                                          approximately two weeks.

                Disputes - international: Antarctic Treaty freezes claims (see

                                          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

                                          to do so); no claims have been made
                                          in the sector between 90 degrees
                                          west and 150 degrees west; several

                                          Continental Shelf to extend their
