Coastal states — Continental shelf — Delimitation — Straits — Territorial sea — UNCLOS (UN Convention on the Law of the Sea)

This final section considers two challenges that arise in connection with the delimitation of continental shelf claims beyond 200M.

The second challenge asks: do geological and geomorphological factors have any role to play in the delimitation of overlapping shelf entitlement beyond 200M and, if so, what is that role? This chapter looks at these two challenges in detail.
