There's been quite a lot in the news recently about maritime boundary demarcation. Argentina have put in a claim for the Falklands, South Georgia, the South Sandwich Islands and part of the Weddell Sea. In fact, you can read all the submissions on the CLCS (Commission on the Limits of the Continental Shelf) website.The Arctic looks pretty busy and, indeed, the more you look the more you find each nation with a coast seems to be involved with some sort of territorial claim. The UK is no exception.
Kenya and Uganda are surveying Migingo to enable boundary delimitation although some wonder if it's worth it.
