Book Description

A report on 3 years of oceanographic investigation in the eastern tropical Pacific Ocean, with the object of understanding environmental properties and processes responsible for changes in the abundance and distribution of yellowfin and skipjack tuna in a way that may lead to prediction of such changes, is presented. The program included field observations by means of cruises and statistical analysis of physical, chemical, and biological measurements obtained on cruises. It also included a laboratory-experimental program to give leads for developing field and statistical work programs, and it encompassed development and testing of moored unmanned instrumented ocean stations to collect and record ocean data.
