Abstract

The cell abundance and marker pigment distriubtion patterns of picophytoplantkon in chuuk Lagoon, Tropical south Pacific, were analyzed using flow cytometry and HPLC. also, the respective contributions of synechococcus, Prochlorococcus and picoeukaryotes on estimated carbon biomass were evaluted. Synechococcus and Prochlorococcus showed contrasting distributional patterns in the waters of Chuuk Lagoon. Relatively high concentrations of synechococcus were observed near Weno Island but the concentration decreased toward the Northeast Passage. ...Estimated carbon biomass of synechococcus contributed 68% of total picophytoplantkon biomass. Prochlorococcus and picoeukaryotes resepctively contributed 17.1% and 14.9% of total picophytolatnkon biomass. Through continuous monitoring, this study endeavors to understand the significance of the Chuuk lagoon ecosystem which is doinated by corals.
