Brazilian Antarctica is the name of the Antarctic territory south of 60°S, and from 28°W to 53°W, proposed as "Zone of Interest" by geopolitical scholar Therezinha de Castro. While the substance of that designation has never been precisely defined, it does not formally contradict the Argentine and British claims geographically overlapping with that zone. The country formally expressed its reservations with respect to its territorial rights in Antarctica when it acceded to the Antarctic Treaty on 16 May 1975, making the first official mention of the Frontage Theory, which states that sovereignty over each point in Antarctica properly belongs to the first country whose non-Antarctic territory one would reach when travelling north in a straight line from such a point. The Frontage Theory was proposed by Brazilian geopolitical scholar Therezinha de Castro and published in her book Antártica: Teoria da Defrontação. Outside the zone of interest, Brazil maintains a permanently staffed research facility, the Comandante Ferraz Brazilian Antarctic Base, located in Admiralty Bay, King George Island, near the tip of the Antarctic Peninsula, at. The peninsula is the northernmost, most accessible, and warmest part of the Antarctic continent and a number of countries, therefore, have research bases located on it.
History
In 1982 the Brazilian government launched their first Antarctic expedition, and a year later built their first base, which has been active year-round since then. Despite their status as newcomers, Brazilian geopolitical writers have had considerable influence on the nation's Antarctic policies, although there is not a national Brazilian Antarctic consciousness similar to that of Argentina. In February 1991, PresidentFernando Collor de Mello reaffirmed Brazil's interest in the region by visiting the Brazilian Antarctic base, where he spent three days. He was the first Brazilian president to set foot in the Antarctic. In January 2008, 13 congressmen members of the Brazilian Antarctica Parliamentary Committee visited the Brazilian Antarctic base. Another visit by the members of Congress took place in January 2009. On February 16, 2008, President Luiz Inácio Lula da Silva and a delegation of twenty-three people, including the First LadyMarisa Letícia, visited country's base in Antarctica. The Brazilian Government defined the presidential trip as a "political gesture" in support of the work displayed by Brazilian scientists and military personnel. In 2009 Brazil made its first national scientific expedition to the Antarctic ice sheet. The expedition integrated atmospheric, glaciological, geological and geophysical studies along the Patriot Hills area and also along the subglacial lakeEllsworth area. A second expedition is scheduled for early November 2011, when researchers will install a monitoring station 310 miles from the Geographic South Pole and 1,600 mi from the Comandante Ferraz Brazilian Antarctic Base.
