Yemen makes submission to the CLCS

(23 March 2009)

The Republic of Yemen has become the latest country to submit details of the outer limits of its continental shelf to the United Nations Commission on the Limits of the Continental Shelf (CLCS).

In a brief executive summary, Yemen identifies a 44,600 square kilometre (13,000 square nautical mile) area of seabed to the southeast of Socotra island which it believes forms part of its continental margin. The outer limit is generated using the Hedberg formula (60 nautical miles from the foot of the continental slope). Eight foot of the slope points have been identified, of which 5 contribute to the outer limit. At no point does the outer limit reach the 350M constraint.

States which became parties to the United Nations Convention on the Law of the Sea before 13 May 1999 have until 13 May 2009 to provide the CLCS with at least a preliminary indication of the location of the outer limit of the continental shelf beyond 200 nautical miles from their baselines.
