 The region of the North Pacific having nearly the 

 same vertical structure as the deep Bering Sea is 

 just southeast of the Okhotsk Sea as shown by Car- 

 negie station 119, 700 nautical miles to the south- 

 west of Attu Island, which has a minimum of 1.6° C 

 at 100 meters. 1M As will be discussed later, the

Carnegie stations show that 600 nautical miles 

 east-northeastward from station 119 toward Adak 

 Island, the temperature at the minimum has increased 

 to greater than 2.5° C and the minimum then dis- 

 appears. 



The horizontal character of the temperature 

 minimum in the deep Bering Sea can be seen from 

 the distribution of temperature and depth at the 

 minimum surface (figs. 2a and 2b), temperature- 

 salinity relationships at selected stations (fig. 3), and 

 from selected vertical sections (figs. 4, 5, and 6). In 

 general, the minimum exhibits a core or tongue-like 

 distribution, with the temperature increasing from 

 northwest to southeast. The depth of the main tongue
