Prior to 2002, Antarctica had no flag, as the condominium that governs the continent had not yet formally selected one. The consultative members of the Antarctic Treaty System officially adopted a flag and emblem in 2002, which is now the official symbol of the continent. Several unofficial designs have also been proposed.
The Graham Bartram design uses the flag of the United Nations as its model. A plain white map of the continent on a blue background symbolizes neutrality. This flag was actually flown on the Antarctic continentfor the first time in 2002, when Ted Kaye took several full-size flags in the Bartram design on an Antarctic cruise. The bases of Brazil, Ukraine, and the UK all flew it from their flagpoles, making its raising "official". He presented a paper which described the first flying of the Bartram design over Antarctica in Stockholm in 2003, at the 20th International Congress of Vexillology. The Graham Bartram design is used for the "Flag for Antarctica" Emoji on all supported platforms.
Territorial flags
The nations of the Antarctic Treaty use their own national flags at their respective Antarctic research bases. Some nations however have their own flags for their Antarctic possessions.
The Antártica Chilena Province in the Magallanes Region includes the Chilean claim on the continent. Puerto Williams is the capital of this province, which also includes the islands south of Tierra del Fuego and Cape Horn. The Magallanes Region's flag also has the Southern Cross appearing over a mountain range. This flag was adopted as the flag of Magallanes Region in 1997 by the regional government.
The flag of the French Southern and Antarctic Territories, which includes Adélie Land, has the French tricolor in the canton together with the Commissioner's logotype. The logotype consists of five stars which represent the administrative districts that make up the territory two of which are archipelagos Illes Crozet & Illes Kerguelen. The third district is made up of Ille Saint-Paul & Ille Amsterdam; the fourth, Ille Eparses, consists of five tropical islands scattered around Madagascar. The fifth district is the Antarctic portion which consists of "Adelie Land".The letters "TAAF" in a monogram. The flag was adopted on 23 February 2007, and was published in the Official Journal of the French Southern and Antarctic Territories on March 15, 2007.
Currently, only the New Zealand national flag serves in an official capacity in the Ross Dependency. The only other 'official' flag seen in photographs was the New Zealand Post flag to denote Scott Base's post office. Ross Dependency uses the New Zealand flag, but vexillologist James Dignan's design concept was seen flying there at one time. The New Zealand flag is the basis for his design, though with an 'Ice Blue' background representing the Ross Sea, and the white horizontal bar at the bottom of the flag representing the Ross Ice Shelf.
