Comparative Analysis of Total and Size-Fractionated Chlorophyll a in the Yellow Sea and Western Pacific.

ABSTRACT: Measurements of different size-fractionated chlorophyll a concentrations (Chl a) of phytoplankton assemblages in situ are vital for advancing our understanding of the phytoplankton size structure and thus the marine biogeochemical cycle. In the present study, we thus made a comparative analysis of total and size-fractionated Chl a in the Yellow Sea (YS) and Western Pacific (WP). Our results suggest that the total Chl a was highly variable in the YS (averaging ~1.02 μg L^-1) and was generally 3-4-fold more than that in the WP (averaging ~0.30 μg L^-1). The pico-sized Chl a had a significant contribution to total Chl a in the WP (range 75-88%), while the average contributions of the nano-sized and pico-sized Chl a to
