Yet critical fields of study exist in which one does need 

 to examine the entire Pacific Ocean, or large sections of it. 

 Some of these fields lie within the range of fishery research. 

 An example might be the investigation of albacore catches 

 of the North Pacific. Here is a fishery that reaches from 

 the shores of North America to those of Japan. If one hopes 

 to investigate the response of albacore to oceanographic 

 conditions, one must consider this entire 6,000-mile-wide 

 sweep of water. 



Faced with a problem such as this, the biologist recog- 

 nizes that he has neither the time nor the professional 

 competence to analyze the scores of separate .studies of an 

 area of this extent. What he needs is a single publication 

 in which all the available information has been evaluated 

 and summarized by an expert in oceanography. 



Adequate publications exist for the surface layer of the 

 Pacific Ocean and for the layers below about 1,000 meters. 

 Yet the chances are great that the biologist's primary
