lies a cold intermediate layer (at a depth of 100 to 200 m), and this is still 

 found at considerable distances from the exit from the Kamchatka Strait. 

 However, its character is not as pronounced in the Bering Sea as in the Sea 

 of Okhotsk, and its usual temperature is above freezing point {Table 323). 



Changes of temperature, salinity and oxygen content can be seen in Fig. 

 414. 



It is clear from the data given that the waters of the Bering Sea and of the 

 adjacent part of the Pacific Ocean have a very similar composition. The 

 amount of oxygen in the depths of the Bering Sea may be, as is shown in 

 Fig. 414, much less than the amounts given in Tables 323 and 324. 



The cold conditions of the Anadyr and Olyutorsky regions are manifest
