along the Alaskan coast. The tenperaturcs and chlorinitjes are too low for 

 water inshore aJ.ong the Siberian coast at the same latitude. The source of 

 this Water must then have boon at a distance, cither north in the Arctic Ocean 

 or southwest in the Gulf of Anadir. Both direct current measurements and 

 calculated currents indicated the latter. This conclusion was substantiated 

 by results from Station 69 which las'" in "ttLe path of any water moving from 

 the Gulf of Anadir to Station 50. The water at 69 was stratiiled as it 

 came from the Gulf but had a moan chlorinity equal to that at 50, showing 

 . that the latter could have been formed hj the mixing of the waters passing 

 north botv/een St. Lawrotico Island and Siberia at, or near, Station 69, 

 This water evidently continued on through Boring Strait in a path not far 

 removod from Station 39. 



In Soction V (Station 36 to 39) taken across Boring Strait at its 

 narrowest point, uniformly high tempor^.turos ;ind low chlorinities wore 

 found near the Alaskan Coast and lev/ temper ;.turcs and high chlorinities on 

 the Siberian side. Each ^vater mass within itself was quite homogeneous duo 

 to mixing ct the entranco to the strait. The differeace be two en the tv/o arose 

 from their sources. The Siberian water came from the cold, relatively con- 

 centrated Gulf of Anadir and flowed toward Borir^ Strait west of St. Lawrence 

 Island, The Al-skan w.ator crane from Bristol Bay and tho Yukon Delta and moved 

 northeast of St. Lawronco Island. At the tv;o stations in the middle of tho 

 section (38 ..nd 39), the lighter Alaskan water ovorflowed the more dense 

 Siberian water causing stratification. 



For the purpose of studyingtidal effects and other variations of 

 a short-time nature, Values of teraper.ature and chlorinity at intervals 

 during a 23-hour period were determined in Bering Strait at Station 45. The 

 properties of the water were practically constant at depths of 25 and 40 

 meters, but temperature values at the surface and 10 meter lovols fluctuated 

 widely. The mean values of temperature and chlorinity have been caaputod 

 and are shown, together with the maximum and moan deviations from tho mean in 

 Table Y.

 23-hour period at Station 45 in Bering Strait 



Tho vertical distribution of taaperature and chlorinity for the deep 

 water stations bets^ecn tho Aleutian Ridge and the Pribilof Islands is perhaps 

 best summarized by average results from several stations. The results from seven 

 auoll stations (102, 105, 106, 107, 117, 118, and 119) have been averaged and ' 

 are shown together with the maximum and mean deviations from the raean in
