Seven countries currently ‘officially’ claim territory in Antarctica. A map of these claims looks like a pie chart, as all are centred on the geographical South Pole(*). If all those claims would be realised, one would be able to visit those seven countries by simply walking in a circle around that one point. But all territorial claims on Antarctica were ‘frozen’ by the Antarctic Treaty of 1961, which also stipulated that thereafter, no new claim could be made. Present claimants are:
- France (Terre Adélie, since 1924)
- Chile (Antárctica, since 1940)
- Argentina (Antártida Argentina, since 1943)
- Australia (Australian Antarctic Territory, since 1933)
- United Kingdom (British Antarctic Territory, since 1908)
- Norway (Dronning Maud Land, since 1939; Peter I Island, since 1929)
- New Zealand (Ross Dependency, since 1923)
All claims apply to the areas south of 60°S, which is the northern limit of the Antarctic Treaty. The area between 90°W and 150°W remains unclaimed, except for Peter I Island, Norway’s claim on this territory being the only one in Antarctica that is not a sector (a ‘slice of the pie’).
This status quo has been maintained ever since 1961, certain signatories – notably the US and the USSR – nevertheless expressing their reservations about certain treaty restrictions. Which could be dangerous, as some claims overlap – notably between Chile, Argentina and the UK. The latter two countries already went to war over the nearby (but non-Antarctic) Falkland Islands in 1982.
A Brazilian geostrategist Therezinha de Castro proposes a different way of approaching the divvying-up of the South Pole – a method which of course is more beneficial to Brazil’s as yet unrecognised Antarctic claims, but which would also eliminate the inherent danger of overlapping claims. It goes like this: all non-South American nations withdraw their claims and bases from the South American sector of Anterctica (from 0°W to 90°W), and this sector is divided among the South American nations according to defrontação. This frontage signifies the ‘open’ sea acces to Antarctica via meridional lines. This would diminish the Chilean and Argentine sectors, give Uruguay, Peru and Ecuador a slice – and would give Brazil the biggest sector.
On reading an Economist article about British territorial claims in Antarctica, Paul Youlten recently came up with a similar idea. “The useful little map (included in the Economist article) got me wondering about which other countries might also lay claim to a slice of Antarctica based on their having un-restricted southern passage across open seas to the continent.”
He used the ‘frontage’ principle not just for South America, but for the whole world. For a bit more about the sources and methods used by Paul Youlten, please click here to read his post on the subject. Via the Youlten method of frontage-ing, no less than 47 countries can lay a claim to Antarctica. To wit:
- From the Americas: USA, Canada, Mexico, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, Peru, Chile, Argentina, Uruguay, Brazil and Greenland.
- From Africa: Senegal, Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, Equatorial Guinea, Gabon, Namibia, South Africa, Mozambique, Kenya, Somalia and Madagascar.
- From Asia: Yemen, Oman, Iran, Pakistan, India, Sri Lanka, Bangladesh, Burma and Indonesia.
- From Oceania: Australia, Papua New Guinea, Solomon Islands, New Zealand.
Remarkably, Iceland is the only European country with direct Antarctic access, unless you count the UK (via the Falklands and South Georgia). “Unexpected results include the surprising news that Somalia, Yemen and Oman could make claims,” says Mr Youlten. “As well as Iran, which I suspect might be tempted to set up an ‘Icelamic Republic’ – sorry, I couldn’t resist that one.”
Will a re-distribution like this ever happen? It reminds one of the attempts to broaden the UN Security Council: the vetoing powers might not all be world powers anymore, but they can still… veto any change, for example to include one vetoing member per continent. This will continue until the UN Security Council or its vetoing members achieve total irrelevance. Similarly, a ‘fairer’ division of Antarctica will not happen until the Treaty signatories are weak enough, or the other parties are strong enough. Which is not anytime soon.
(*) even though the Norwegian claim is only defined east-west, not north-south, and therefore in theory does not extend all the way down to the Pole itself.



Poorly done.
Portugal would have direct access through the Azores islands, grabbing a bit of Greenland’s sector. Cape Verde would also have a slice, taken from Greenland and probably Portugal. São Tomé e Príncipe would also grab a bit. The UK would have a bit more due to St. Helena and its dependencies. France would also keep a claim due to Kerguerlen and other Indian Ocean possessions, and other Indian Ocean insular nations would also have sectors. A whole bunch of Pacific nations would also have slices, taken from the american sector (mostly from Alaska).

Intriguing, but I agree with Jorge that it is rather poorly done. Part of the problem in the Pacific, I suppose, is how you define borders. Most of the Pacific island nations have large borders that contain mostly water. Do you use those or do you use landfalls? Also, it should be noted that Greenland is not an independent nation, but a semi-autonomous dependency of Denmark, so the Danes also get a slice.
Comment by DemetriosX — November 20, 2007 @ 5:45 pm
Hi Jorge and DemetriosX, I made the chart very quickly out of curiosity and didn’t include various islands including the ones Jorge mentions. Also, I didn’t have a good way to get the south pole located and the outline of Antarctica isn’t correctly aligned. If you want to improve on what I have done you can download the datafile from my blog. I Look forward to seeing an improved version.
Comment by linksandanchors — November 20, 2007 @ 6:53 pm
As as French, I violently oppose this chart. It does not take into account the French islands in the south Pacific (Kerguelen, New Caledonia….)
Seriously, Antarctica is a far better place as an international playground for scientists and penguins.

I disagree. Far better to have the Great Powers fight their territorial wars fought in a place where there are no (human) natives to get caught in the crossfire.
Comment by mollymooly — November 20, 2007 @ 8:58 pm
I’d say there’s a good chance of them fighting there as well, Mollymooly. We’re all seeing the manoeuvring for the Arctic, and Britain’s FCO is now planning to consolidate its Antarctic claims.
Comment by Dave On Fire — November 20, 2007 @ 10:15 pm
The problem with this idea is that it has a huge bias in favor of countries that are closer to the poles… whereas equatorial countries see their share diminish as you get closer to the poles. Look at the huge chunk that is Alaska… it’s because it’s so far North… if you draw lines straight down, the width grows as you get to the equator, then shrinks back down to almost normal size. Whereas a country like Mexico, nearer the equator, just shrinks (rather than growing and then shrinking).

“The latter two countries already went to war over the nearby (but non-Antarctic) Falkland Islands in 1982.”
On the contrary, the Falklands War was not about the Falklands, but about Antartica. If the UK had lost control over the Falklands and St Georges islands, it would have lost any claim to a slice of Antartica. And underneath the ice is a mssive continent rich with minerlas, gold and oil. Well worth fighting over. Killing over, I should say.
If you thought the Falklands War was about saving a failing sheep farm from the Argies, go to the back of the class.
Comment by jon — November 21, 2007 @ 12:15 am
Dear Krysztof, As I say in my blog and as I mentioned here to Jorge and DemetriosX: please download the datafile that I made and improve it. The only reason I left off the French islands was because I didn’t have time to index every tiny island in the Pacific and Southern oceans. I am sure you can improve it (and restore French pride) quite easily.
Comment by linksandanchors — November 21, 2007 @ 1:47 am
Hi Corbyz, it would be interesting to see the same map but have frontage rights “cut-off” off at the equator (which I think is the Brazillian proposal: http://en.wikipedia.org/wiki/Brazilian_Antarctica)
Comment by linksandanchors — November 21, 2007 @ 1:55 am
Doesn’t the west coast of Canada have ‘frontage’ on Antarctica too?
Comment by rek — November 21, 2007 @ 2:37 am
Canada does get a slice, on the basis of British Columbia — I don’t believe any other province has frontage.
The British Columbian territory is in turn invaded by four quite thin slices representing the Pitcairn Islands. Whether the Pitcairners or the British would have rights to the mineral wealth of these claims is matter unresolved by international law.
Comment by Will — November 21, 2007 @ 6:28 am
Incidentally, there’s an easy way to resolve the frontage issue. In Google Earth, open the Ruler tool and place one end of a line on the South Pole, and lay the other end on the territory you want to test. Then simply take a look over the yellow line to see if it intersects any little islands along the ocean path.
Comment by Will — November 21, 2007 @ 6:31 am
Oh — and there’s another claimant in the Canadian Antarctic, one whom we ignore at our peril. Attentive readers will remember that the lost city of R’lyeh is located at approximately 47°9′S, 126°43′W, and therefore lies in the path of Canada’s frontage. The width of this claim will vary with the stars, as R’lyeh rises and falls from the sea periodically. It’s frontage depends on the surface width of the protruding towers, and these can difficult to calculate owing to the non-Euclidean geometry in effect locally.
Comment by Will — November 21, 2007 @ 6:39 am
Interesting that the discoverers of the Antarctic receive nothing according to this map :)
Comment by Dmitri Minaev — November 21, 2007 @ 7:53 am
I agree with Dmitri, usually/legally the discoverers/explorers are the ones than can claim a territory. After all, they have invested time, money and sometimes their lives while countries who are nearby sometimes did absolutely nothing.
Let’s also not forget a whole bunch of countries like Belgium who had a right to claim land but chose not to do so in the general interest.
Comment by Johan Van Loon — November 21, 2007 @ 10:18 am
I suspect the lack of European claims is due to Africa being in the way.
Strangemaps, the last two paragraphs in your article (ignoring the footnote) are too small. Enlarge them to the size of the previous paragraphs.
Comment by Darrel Jones — November 22, 2007 @ 12:47 am
Add the Galápagos (Ecuador) to the list of ignored islands.
And here’s a map of the current claims http://flagspot.net/flags/aq(.html and and a list of these and other claims http://flagspot.net/flags/aq(.html

Question: Why does the US have two sectors right next to each other?
Comment by Lurker — November 25, 2007 @ 2:45 am
Argh, I missed Canada, sorry, nevermind.
Comment by Lurker — November 25, 2007 @ 2:45 am
No, I have the same question as Lurker, but don’t understand his own answer to his question?
Why does the US have two sectors right next to each other?
Lurker then answered himself, “Argh, I missed Canada, sorry, nevermind”.
But that’s not the problem – the problem is that the US has THREE sectors, and two of them ARE right next to each other.
Starting at the Mexican sector and going counterclockwise, the map has:
1. Mexico
2. USA
3. Canada
4. USA
5. USA
6. New Zealand
Why are 4 and 5 not just one single sector?
Comment by blonk — November 25, 2007 @ 5:38 pm
perhaps 4 is from alaska and 5 from hawaii?
Comment by Dave On Fire — November 25, 2007 @ 9:37 pm
there are other islands which could claim a (very thin) slice I think.. the maldives, tonga, samoa
Comment by roke — November 26, 2007 @ 4:33 am
So, what are you all going to do with all that land down there?
Maybe proceed with the pollution and global warming to scrape all the ice there?
Comment by Mladen Postruznik — November 28, 2007 @ 8:07 am
Ahhhh. But you have all failed to notice that the US portion is missing the most land…because it has melted away. How telling. We can thank our SUVs, among other things, for that.
Comment by alex — December 5, 2007 @ 3:58 pm
Nevermind my “realization”: I was looking at the OTHER two US sectors.
Alex: Antarctica has had that shape for ages, and global warming isn’t quite so nationalistic in its effects.
I now think I know: The two US sectors are for Hawaii and Alaska, but someone forgot to include Russia or something. This way it goes Hawaii, Alaska, British Columbia (Canada), the West Coast (US), then Mexico and so on down and up the Southern American coast.
Comment by Lurker — December 9, 2007 @ 3:39 am
As an Icelander, I approve of this division. :)
Comment by Bjarki — December 9, 2007 @ 6:18 am
Two countries that were left out are: Kingdom of Zamumda and Parador.
Comment by quasidailynews — December 11, 2007 @ 3:12 am
Question from blonk:
“Starting at the Mexican sector and going counterclockwise, the map has:
1. Mexico
2. USA
3. Canada
4. USA
5. USA
6. New Zealand
Why are 4 and 5 not just one single sector?”
The USA sectors going anti-clockwise are:
1. Mexico
2. USA – California
3. Canada
4. USA – Alaska (up to 180°)
5. USA – Alaska (West of 180°)
6. New Zealand
It turned out like this I started collecting data from 180° line it was what I used to orient the pie chart onto the map.
Comment by linksandanchors — December 12, 2007 @ 7:11 am
Interesting. I still strongly prefer the idea that no country owns any part of the continent though, and am surprised that nearly all the commenters are already scheming about plans to take profitable advantage of the would-be territorial claims. I think if we’re just guests, there’s a higher likelihood we might treat Antarctica well, and not, for example, plunder its resources the way we do everywhere else.

The map is poorly divided, in fact no country from the northern hemisfere will have any right over the Antarctica because of his continental area, only if they have an island or so in the southern hemisfere.
That’s why no area should belong to japan, or russia or us… hehe… a war over an ice rock!
