APPENDIX C TO STATEMENT OF 
NORTHCUTT ELY 
COASTAL STATE MINERAL JURISDICTION 
AND THE CONTINENTAL MARGIN 
Survey of National Practice 
To date, 102 nations, 1/ including 98 coastal nations, have 
recognized the principle of the coastal state's jurisdiction over adjacent 
offshore mineral resources. Thirty-nine nations (35 of them coastal) 
have asserted this principle by ratifying the Convention on the Continental 
Shelf. 2/ The other countries have done so by one or more of the follow- 
ing methods: (1) by domestic legislation, (2) by agreement with other 
nations, or (3) by granting offshore concessions. 3/ 
Of the 98 coastal nations which have asserted their general juris- 
diction over offshore minerals, at least 37 have done so with respect to 
specific submarine areas which, according to available information, ap- 
pear to be beneath waters deeper than 200 metres. In most cases, this 
has been done by the issuance of deep-water leases; 4/in others by de- 
cree, agreements with neighboring states or offers of such agreements, 5/ 
or announcements of national policy. 6/ Atleast 14 coastal nations have 
if These 102 are identified in Parts I, II, and III of this Appendix. To 
these 102 nations may be added 5 territories which are partially self- 
governing, making a total of 107 jurisdictions. See note 9 infra. 
ei These 39 are identified in Part I of this Appendix. 
ims These 63, plus 5 territories which are partially self-governing, are 
identified in Parts II and III of this Appendix. 
4/ 31 nations which have apparently authorized or undertaken development 
in water deeper than 200 meters are identified in Part IV of this Appendix. 
5/ Decrees or international agreements or tenders of international agree- 
Ments have been found to include water deeper than 200 metres in instances 
which involve eight nations, in addition to the 31 nations which have issued 
deep-water leases. These eight are: Chile (200 miles); Dahomey (100 miles); 
East Germany (Baltic Sea Decree); Ecuador (200 miles); El Salvador (200 
miles); Poland (Baltic Sea Decree); Saudi Arabia (Red Sea Decree); U.S.S.R. 
(Baltic Sea Decree). See also Soviet announcement in the U.N. of drilling in ~ 
Caspian Sea at depths of 300 to 600 metres (Press release GA/3929, 13 March 
1969, p.4). 
6/ For example, Canada.
