 and Charles R. Hebard 



ABSTRACT 



Oceanographic data in Bristol Bay and the Bering Sea obtained 

 aboard the U, S, Coast Guard Tug i2ecfz<;zng"during the summer months 

 of 1939, 1940 and 1941 in conjunction with the exploratory fishing 

 conducted in the area are presented. Tennperature, salinity, dis- 

 solved oxygen, phosphates, nitrites and silicates are tabulated for 

 331 stations in 1939, 184 in 1940 and 40 in 1941, Interpolated values 

 of temperature and salinity and connputed values of density, specific 

 volume anomaly, and dynamic height at standard depths are presented. 



INTRODUCTION 



This report supplements current in- 

 vestigations of the distribution and 

 migration of salmon in the North 

 Pacific Ocean and the Bering Sea and 

 follows the report by Favorite and 

 Pedersen (1959) in which the basic 

 operational plans and the results of the 

 1938 preliminary oceanographic inves- 

 tigations in Bristol Bay, Alaska, were 

 presented. 



The oceanographic data presented in 

 this report were obtained during the 

 summer months of 1939 to 1941 aboard 

 the U. S. Coast Guard Tug Redwing in 

 conjunction with the exploratory purse- 

 seine and gill-net salnnon fishing con- 

 ducted in the area. The results of the 

 fishing effort have been reported by 

 Barnaby (1952).
