 Sverdrup and Munk, 1946a, b). Research on the Sofar (for $ound 

 Fixing And .Ranging) network, recently established in the northeast 

 Pacific by the Navy Electronics Laboratory for air-sea rescue pur- 

 poses, should yield additional data of geologic importance (Ewing, 

 Woollard, Vine, and Worzel, 1946; Ewing, Worzel, and Pekeris, 1948; 

 Russell, in press). 



Navy research thus offers many opportunities for those interested 

 in marine sediments and submarine geology. Naval vessels provide 

 means for taking data in all parts of the oceans. These data, with the 

 research underway at Navy Laboratories and in private institutions on 

 Navy contracts, are rapidly expanding our knowledge of the oceans, 

 their processes, and their sedimentary products. This expansion may 

 be expected to continue so long as funds are made available for re- 

 search.
