preface 



This volume presents the basic oceanographic station data obtained in the shallow 

 eastern Bering and Chukchi Seas and eastern Bering Strait during a joint Canadian-U. S. 

 scientific expedition in the summer of 1949. The de«cription of the cruise and analysis 

 of the data are contained in volume 1. The data are presented here in tabular form 

 for the information of those interested in the details of the studies. For conclusions 

 drawn from these data and for discussion of the findings, the reader is referred to 

 volume 1. 



administrative information 



The oceanographic program was carried out as a joint investigation by oceanog- 

 raphers of the Pacific Oceanographic Group and Defense Research Board of Canada 

 and the U. S. Navy Electronics Laboratory. The reduction of the data, by prior agree- 

 ment, has been carried out at NEL. 



Personnel who contributed to the many phases of the task are as follows: 



OBSERVATIONAL PROGRAM ABOARD HMCS CEDARWOOD 



Pacific Oceanographic Group and Defense Research Board, Canada: J. P. Tully, 

 Scientist in Charge; F. G. Barber; A. J. Dodimead; R. H. Herlinveaux; G. L. Pickard. 

 U. S. Navy Electronics Laboratory: E. C. LaFond; R. M, Lesser; J. C. Roque; and

REDUCTION OF DATA 



U. S. Navy Electronics Laboratory: A. J. Carsola; B. E. Holtsmark; R. M. Lesser; 

 J. F. T. Saur. 



The participation of personnel of the Propagation Division of NEL in the observa- 

 tional program in the summer of 1949 and the reduction of data (1950 and 1951) were 

 accomplished under IO 15401, NE 120221-3 (NEL L4-1). The report covers work to 

 January 1954 and was approved for publication 27 May 1954. The formal publication 

 of data has been delayed until completion and publication of the final analysis. 



explanation of data 



OCEANOGRAPHIC STATIONS 



The locations of oceanographic stations occupied in the shallow regions (shelf 

 area) of the eastern Bering and Chukchi Seas and in eastern Bering Strait are shown 

 in figure 1. At most of the stations temperatures were obtained with a bathythermograph 

 and water samples for chlorinity titration by water bottles without reversing thermometers 

 (see volume 1 for details). From several locations made early in the survey in the Eastern 

 Bering Sea only bathythermograms are available. These locations are indicated in the 

 figures but the data have not been tabulated. Bathythermograms are filed in the 

 Bathythermograph Section, Scripps Institution of Oceanography, La Jolla, California, as 

 Cruise No. 606.
