Argentine Antarctica mainland. Argentina was the only nation to have an Antarctic base for 40 years until the British built a base on the same islands. Argentina bases its claims on this sector of Antarctica on the following grounds: Argentina's claim to the Antarctic Peninsula overlaps with the Antarctic claims of Chile, 53°W to 90°W, and the UK claims, 20°W to 80°W. Currently, there are no attempts by Argentina or any other country to enforce territorial claims in Antarctica. See List of Antarctic territorial claims. None of these claims have international recognition and have been suspended by the Antarctic Treaty in 1961.
Antarctica: A Year on Ice Antarctica: A Year on Ice Antarctica: A Year on Ice is the first feature film by New Zealand filmmaker Anthony B. Powell. This documentary is set in Antarctica, specifically in the Ross Island region, which is home to two research bases: United States' McMurdo Station and New Zealand's Scott Base. It chronicles a year of time spent living and working at these remote stations; the summer season (October to February) when the sun shines 24 hours a day and the long dark winter (February to October) where the sun goes down for four long months and darkness envelopes the environment.
