ABSTRACT 



Results of oceanographic operations conducted by the 

 USS REQUISITE, USS ELDORADO, and USS ATKA in the 

 western Arctic and by the USCGC EASTWIND in the eastern 

 Arctic during summer and autumn 1956 are presented herein. 



Despite heavy ice conditions and limited time for ocea- 

 nography because of higher priority assignments, fifty-four 

 oceanographic stations were occupied. Twenty-sevens sta- 

 tions were taken in the Beaufort- Bering Seas area; thirteen 

 in the Northwest Passage from Amundsen Gulf to 95° W, east 

 of King William Island; and thirteen in the Baffin Bay-Davis 

 Strait area. 



In addition, thirty-one bottom samples and thirty-eight 

 current stations were taken. Bottom samples were collected 

 by Phleger corer and Orange-peel grab sampler; current 

 velocity and direction were measured by Ekman meter. Two 

 of the current stations were 24- hour stations and were located 

 off Point Barrow, Alaska. 



Serial data listings for the oceanographic stations are 

 presented subsequent to figures showing their locations. 

 Included in these listings are temperature, salinity, density, 

 sound velocity, and anomalies of dynamic depth.
