Antarctica/Transnational issues

Disputes - international: Antarctic Treaty defers claims (see Antarctic Treaty Summary in Government type entry); sections (some overlapping) claimed by Argentina, Australia, Chile, France (Adelie Land), New Zealand (Ross Dependency), Norway (Queen Maud Land), and the United Kingdom; the United States and most other nations do not recognize the territorial claims of other nations and have made no claims themselves (the US reserves the right to do so); no formal claims have been made in the sector between 90 degrees west and 150 degrees west
