PICO-PHYTOPLANKTON DISTRIBUTION IN WESTERN PACIFIC OCEAN ESTIMATED FROM OCEAN COLOR AND SST

To investigate the spatial distribution of pico-phytoplankton in surface water, photosynthetic pigments were analyzed by a high-performance liquid chromatography (HPLC) for three cruises in the western Pacific Ocean carried out on 2000, 2001 and 2002. Analyzed chlorophyll-a showed peaks at the equat...

From these results, we found inverse relationship between the ratio of zeaxanthin to chlorophyll-a concentration (ZCR) and chlorophyll-a concentration, and also positive relationship between ZCR and sea surface temperature (SST).
