The Delineation of Indonesia’s Outer Limits of its Extended Continental Shelf and Preparation For its Submission: Status And Problems

Introduction

• Article 76 of LOSC: coastal States may Extend their Continental Shelf beyond 200 nautical miles � Extended Continental Shelf.

• Delineating the outer limits of the ECS, making submission to the commission on the limit of continental shelf (CLCS) through UN Secretary General.

• Eight submissions have been made by Coastal States (as of December 2007).

• Indonesia has ECS potentials but has not yet made any submission. Delineation is being undertaken

• Deadline for submission is on 13 May 2009.
