ABSTRACT 



Oceanographic and meteorological observations obtained aboard the United States Fish and 

 Wildlife Service research vessels Hugh M. Smith and John R. Manning during Operation N E P A S in 

 1957 and en route to and from Hawaii are presented in this report. It also contains a sunnmary of the 

 limited oceanographic observations made by the eight contract vessels. Data are published without 

 analysis or interpretation to make them available to other investigations in the north PACIFIC area. 



The field and laboratory procedures are briefly described. The vertical and horizontal distri- 

 bution of temperature, salinity .dissolved oxygen, and inorganic phosphate off the coasts of California 

 Oregon, and Washington are presented in tables, station curves, and surface plots. Secchidisc, Forel 

 color, and photometer measurements are tabulated by vessel.
