edge. Ships of all nationalities must respect 

 these safety zones. 



4. Such installations and devices, though 

 under the jurisdiction of the coastal State, 

 do not possess the status of islands. They 

 have no territorial sea of their own, and 

 their presence does not affect the delimita- 

 tion of the territorial sea of the coastal State. 



5. Due notice must be given of the con- 

 struction of any such installations, and per- 

 manent means for giving warning of their 

 presence must be maintained. Any installa- 

 tions which are abandoned or disused must 

 be entirely removed. 



6. Neither the installations or devices, nor 

 the safety zones around them, may be estab- 

 lished where interference may be caused to 

 the use of recognized sea lanes essential to 

 international navigation. 



7. The coastal State is obliged to under- 

 take, in the safety zones, all appropriate 

 measures for the protection of the living 

 resources of the sea from harmful agents. 



8. The consent of the coastal State shall 

 be obtained in respect of any research con- 

 cerning the continental shelf and undertaken 

 there. Nevertheless, the coastal State shall 

 not normally withhold its consent if the re- 

 quest is submitted by a qualified institution 

 with a view to purely scientific research into 

 the physical or biological characteristics of 

 the continental shelf, subject to the proviso 

 that the coastal State shall have the right, if 

 it so desires, to participate or to be repre- 

 sented in the research, and that in any event 

 the results shall be published. 



Article 6 



I. Where the same continental shelf is 

 adjacent to the territories of two or more 



States whose coasts arc opposite each other, 

 the Ix)undary of the continental shelf apper- 

 taining to such States shall be determined 

 by agreement between them. In the absence 

 of agreement, and unless another boundary 

 line is justified by special circumstances, the 

 boundary is the median line, every point of 

 which is equidistant from the nearest points 

 of the baselines from which the breadth of 

 the territorial sea of each State is measured. 



2. Where the same continental shelf is 

 adjacent to the territories of two adjacent 

 States, the boundary of the continental shelf 

 shall be determined by agreement between 

 them. In the absence of agreement, and un- 

 less another boundary line is justified by 

 special circumstances, the boundary shall be 

 determined by application of the principle 

 of equidistance from the nearest points of 

 the baselines from which the breadth of the 

 territorial sea of each State is measured. 



3. In delimiting the boundaries of the 

 continental shelf, any lines which are drawn 

 in accordance with the principles set out 

 in paragraphs i and 2 of this article should 

 be defined with reference to charts and geo- 

 graphical features as they exist at a particu- 

 lar date, and reference should be made to 

 fixed permanent identifiable points on the 

 land. 



Article 7 



The provisions of these articles shall not 

 prejudice the right of the coastal State to 

 exploit the subsoil by means of tunnelling 

 irrespective of the depth of water above the 

 subsoil.

 in nature and have been omitted,]
