Abstract

Primary productions in the western tropicl Pacific and equatorial warm waters are studied in the WOCE cruise in November 1991and the TOGA-COA RE cruises from November 1992 to February 1993.It is shown that total amount of integrated chl a is 19.79 mg/m² in depth of 0~150 m and averagedaily primary production with, 171 mg/(m²·d) appears in the western tropical Pacific while higher chl a(21.68 mg/m²) and primary pr oduction [228 mg/(m²·d) ]occur in equatorial warm waters.The higher chl a is found at the coastal stations of the Philippines and Pulau Irian while lower chl a is at the offshore areas bounded by 2°~4°N.It shows that the distribution pattern of chl a biomass is related to different physical processes.Upwelling,which may have led to a high biomass, is a critical factor varying the distributions of temperature,sanility and nutrient in these areas.
