Rock samples from the Florida Straits and the West Florida Shelf, 

 and sediment cores from the North Pacific, collected from Coast Survey 

 ships, have been analyzed by the U„ S„ Geological Survey on a 

 cooperative basis., and marine geophysicists from that agency and from 

 the Scripps Institution of Oceanography have and will continue to work 

 with the Coast Survey on cooperative research projects „ 



During FY-1962, the extensive ocean-wide survey operations in the North 

 Pacific provided, for the first time, accurately controlled data from 

 which the Coast Survey is constructing charts which will show for the 

 same area the total magnetic field, the gravity anomalies, and the 

 bottom topography„ These are valuable research tools for studies 

 of the geologic history of the ocean basin. 



During FY-1962, the Coast Survey made its first research grant for 

 marine geological research. This was to a graduate student at Johns 

 Hopkins working on the problem of underwater sand ridges. This 

 grant will probably continue in FY-1963? and it is planned that others 

 will be made when the funds become available « 



DEPARTMENT OF THE INTERIOR 



Bureau of Commercial Fisheries FY-62 $11, 000 



FY-63 $ 9,000 

 The Bureau's program does not contribute significantly to this Objective, 

 although an increasing awareness of the relation of fisheries to topo- 

 graphic features is being followed closely. In cooperation with 

 Scripps Institution of Oceanography, a series of topographic charts 

 showing locations of sea mounts in the eastern Pacific is being 

 produced. These are for use primarily by tuna fishermen, as past 

 research has shown that tuna concentrate near sea mounts. 



Geological Survey FY-62 $205,000 



FY-63 $230,000 

 The Geological Survey program contributing to knowledge of the sea floor 

 and marine sedimentary processes can best be illustrated by the 

 following tabulation of long-range programs to begin or to be extended 

 in FY-63 c 



1) Structure, geologic evolution, and sedimentation 

 of the Pacific continental margin, Western United 

 States „ 



2) Geologic history, substructure, and sedimentary 

 regime of the Alaskan epicontinental seas and 

 the Aleutian Island arc, 



3) Petrogenic provinces and boundary structures of 

 the Pacific Basin,
