Unimak Island, however, two stations were occupied during 

 the search. En route from Unimak Island to San Francisco 

 only periodic bathythermograph lowerings and surface ob- 

 servations were made. 



In harbors such as Village Cove (St. Paul Island), Fort 

 Clarence, Womens Bay and Middle Bay (Kodiak), Resurrection 

 Bay (Seward), and Gasteneau Channel and Taku Inlet (Juneau), 

 motor launches were used to make additional measurements . 

 Although insufficient time prevented making detailed surveys , 

 it was possible at several locations in each of the above har- 

 bors to take bathythermograph lowerings and bottom samples 

 and to make ambient noise measurements. 



Oceanographic measurements were taken from the subma- 

 rines as well as from the USS NEREUS. The USS BOARFISH 

 dropped SOFAR bombs each day while en route from San Diego 

 to Adak. In the Bering and Chukchi Seas observers on all four 

 submarines took continuous soundings on recording fathom- 

 eters, observations of sea and swell, and observations of ice 

 limits and conditions. Observers on the USS BOARFISH made, 

 in addition, bathythermograph lowerings from the surface in 

 the ice region and obtained temperature and salinity readings 

 en route through the Chukchi and Bering Seas by means of the 

 ship's recording instruments. 



The data collected by all ships are discussed in this report 

 by subject and in some cases are combined with existing in- 

 formation of the area. The data on weather, depth, ice, sea, 

 swell, discolored water, phosphorescence, birds, whales, 

 and fish, as well as the bathythermograms taken south of the 

 Bering Sea, were turned over to the U. S. Hydrographic Office. 

 These data have thrown some new light on the subject of 

 oceanographic conditions in the arctic and have served to 

 corroborate the findings of previous investigations. It is 

 expected that this report will serve as a basis for further 

 analyses of arctic conditions.
