The Antarctic Peninsula is currently dotted with numerous research stations and nations have made multiple claims of sovereignty. Therefore peninsula is part of disputed and overlapping claims by Argentina, Chile and the United Kingdom. Also none of these claims have international recognition and, under the Antarctic Treaty System, the respective countries do not attempt to enforce their claims. The British claim is recognised though by Australia, France, New Zealand and Norway. Argentina has the most bases and personnel stationed on the peninsula.
