Interpretation of the geophysical data will be enhanced by better 

 bathymetry and by more complete knowledge of coastal stratigraphy than 

 is now available. New bathymetric charts of the sea floor off western Af- 

 rica are being prepared in South Africa and in the U.S.S.R., and these will 

 be improved by new soundings obtained during the Atlantis II cruises. 

 Similarly, maps of the sediments on the continental shelf are being pre- 

 pared on the basis of several thousand samples between Gibraltar and Ni- 

 geria, assembled from many organizations. 



The geophysical results, which will be published and made available 

 to all, should provide enough information to permit the drawing of maps for
