CONTRIBUTIONS TO THE STUDY OF PACIFIC CIRCULATION 611 



HORIZON in such expeditions as Mid-Pac (1950), Northern Hoh'day 

 (1951), Shellback (1952), and Capricorn (1952-53), and of the Univer- 

 sity of Washington research vessel BROWN BEAR. 



The third action to be mentioned was the establishment of an 

 oceanographic unit under Mr. E. C. LaFond at the U. S. Navy Elec- 

 tronics Laboratory (LaFond, 1949). In addition to studies of the Pacific 

 with the immediate objective of defining the sound channels or Sofar, 

 LaFond's group has participated in surveys in the Antarctic (Dietz, 

 1948) and in the Bering Sea (LaFond, et ah, 1948, 1952), cooperating 

 in the latter area with Canadian authorities (Lesser and Buffington, 

 1950). Sofar cruises have been performed by the USS FIEBERLING 

 (Holtsmark, 1949) and SERRANO (Anderson, 1950); and the EPCE(R) 

 854 has also carried out similar work. 



In addition to the data contained in the publications already cited, 

 most of the observations made by the vessels mentioned have been 

 punched onto cards (Fig. 3) as described by Lyman (1953). H. O. Pub. 

 No. 242 lists the cruises which have been so punched, and H. O. Pub. 

 No. 238 is a comprehensive bibliography of the physical oceanography 

 of the Western Pacific.
