Brazil's First Expedition ~ 1982-1983
Brazil made its first Antarctic
expedition in 1982-83. The stamp shows an Adeliea Penguin, a small
polar projection of the Antarctic continent, and the
support ship, Barão de Teffe. The Barão was built in 1957 and was used
by the French Antarctic Territories for 18 years under the name Thala
Dan. It was sold to Brazil in 1982.
Brazil owns a permanent base on King George Island, off
the long finger south of South America, and
has been granted a zone of interest between 28°W and 58°W, which
overlaps territory claimed by Argentina, Great Britain, and Chile.
