ABSTRACT
This contribution aims to address maritime boundary delimitations in the polar regions. Maritime boundaries are delimited between opposite or adjacent States, with overlapping claims to maritime zones. The Arctic is a prime example of a region where maritime boundaries have been peacefully delimited. There are several instances of overlapping maritime claims in the Arctic, and most have avoided third-party involvement. Despite various assertions about a rush for Arctic resources in the context of the continental shelf beyond 200 nautical miles, the States involved are engaged in a constructive process and are following the procedures set out in the international law of the sea.
Maritime delimitation in Antarctica is more complicated. Currently, no maritime boundaries in that region exist because maritime claims can only extend from territory subject to coastal State sovereignty, and sovereignty over the Antarctic territory is generally contested or subject to restrictions. Nonetheless, unilateral maritime claims have been put forth, and whether they will give rise to maritime delimitation in Antarctica remains to be seen.
