UNCLOS ratification is key to securing claims to Arctic resources through CLCS

UNCLOS holds specific value for the Arctic security environment as it lays out a set of rules on how to divide disputed territory and resolve possible tensions. It also represents the only path for Arctic coastal states to submit scientific claims to extend their outer continental shelf, which provides important clarity for future economic development. While the five Arctic coastal states are limited by their exclusive economic zone of 200 nautical miles from their coasts, the convention allows them to extend their economic zone if they can prove that the Arctic seafloor’s underwater ridges are a geological extension of the country’s own continental shelf. Within 10 years of ratifying the UNCLOS, countries must submit evidence to the UN Commission on the Limits of the Continental Shelf, the governing body created to deliberate on these submissions, to make their case for an extended continental shelf.
