3.12 ^ 10" metric tons. The area of the Bering Sea is 

 2.268X 10''km-(Sverdrup<'?a/., 1942). The mean productivity 

 rate for the entire Bering Sea (excluding Station 36) amounts 

 to 1 .4 g C m - d ' , or 0. 1 9 X 10'' metric tons during the growing 

 season. 



Discussion 



Oceanographers have become more aware of the 

 importance of primary production in the Bering Sea since the 

 charts of Koblentz-Mishke fro/. ( 1970) were published. More 

 recent estimates of the magnitude of primary production range
