What is the nationality of someone born in Antarctica?

Jus sanguinis would apply if you were born in Antarctica, i.e. you would be a citizen of the country where your parents are registered. Jus sanguinis (right of blood) is a principle of nationality law by which citizenship is not determined by place of birth but by having one or both parents who are citizens of the state. I guess than means most people born there would be Argentinian or Chilean as most people who work there are citizens of those countries.

Would I live there if the UK crumbled? A bit too chilly!

Not sure many people born there... Hmm just checked... They have their parents nationality..
