The Nash collection contains a number of files related to Antarctica.
Antarctica has no government, although various countries claim sovereignty in certain areas. New claims on Antarctica have been suspended since 1959 and the continent is considered politically neutral. Its status is regulated by the 1959 Antarctic Treaty which New Zealand and eleven other countries initially signed, (and other related agreements, collectively called the Antarctic Treaty System). These countries had established over 50 Antarctic Stations for the International Geophysical Year (see item below).
