No one owns Antarctica but seven countries have made claims, including Argentina, Australia, Chile, France, New Zealand, Norway, and the UK, Australia has the biggest claim. Some of these claims overlap each other.
All land on earth south of 60 degrees S is under the governance of the Antarctic Treaty. The treaty lists these land claims, holds them in abeyance and prohibits future claims by any nation-state.
Since it's discovery in the 1800s, there has never been 'ownership' of the Antarctic continent. There have been claimants, all of which were put on hold by the Antarctic Treaty of 1960.
Antarctica, all the other continets have partial ownership of Antarctica
There is no ownership of an 'Antarctica post office'. Each research station organizes the logistics of sending and receiving mail.
No land south of 60 degrees S on earth is 'owned' by anyone, nation-state or otherwise. All this land is governed by the Antarctic Treaty, which specifically holds all existing land claims in abeyance, and prohibits future land claims. Ownership of Antarctica is not important, because the phenomenon does not exist.
Russia is the biggest country in the world at 17,075,400 sq km. Antarctica is not a country but a territory, with disputed ownership. Besides, it is only 13,209,000 sq km.
All humans benefit from the Antarctic Treaty, which governs all land south of 60 degrees S, including Antarctica. Ownership is non-essential to the scientific work accomplished on the continent.
Antartica has no gernment. It signed a peace treaty with 12 other countries saying that no one has a ownership right to any of Antartica's land.
Antarctica is a condominium in the sense of ownership, and the governing document is the Antarctic Treaty. Australia, Great Britain, Chile, Argentina, New Zealand, France, Norway -- to name a few -- are all in agreement as to the use of the land on earth south of 60 degrees S, which includes the continent of Antarctica.
Antarctica doesn't have an official currency. There is no nation state to establish currency, postage stamps, flags or other items showing national ownership. Any currency, stamps, flags or so forth that purport to be 'official' anything from Antarctica are souvenirs crafted by clever entrepreneurs.
The Antarctic Treaty specifically forbids ownership of any territory on the Antarctic continent by any country. The treaty acknowledges claims made by several countries, some of which overlap, and renders them moot. The treaty also prevents additional territorial claims.
No, no nation owns any part of Antarctica. Several nations have territorial claims on the continent -- not USA, however -- some of which overlap each other. The Antarctic Treaty (1960) holds all claims in abeyance and forbids any other future claims.
There is no sovereignty in Antarctica, and so any flag you see has been developed and sold by a souvenir-selling profiteer. That person can explain to you what the colours of that souvenir represent. Antarctica is governed by the Antarctic Treaty, which is a form of condominium ownership. There is no government to issue a flag, currency or postage stamps.
By universal treaty agreement, no country owns any specific rights or ownership over the continent of Antarctica. Therefore, Antarctica contains no country. During the short Antarctic summer season, many countries carry out scientific study groups. But they leave at the approach of the Antarctic winter.
