Abstract
This study focus on spatial variation of the phytoplankton pigments in coastal surface waters off Taiwan. Results show that the concentration of pigments were found highest near the Main land coast with decreasing trend toward Taiwan. The maximum concentration of chlorophyll a was found near the river mouth of Ming Jiay. Total pigments concentration range from 0.02μg/L to 4.85μg/L, there are seven pigments detected namely 19-Butaloxyfucoxathin, Chlorophyll a, Chlorophyll b, Diadinoxathin, Fucoxathin, 19-Hexaloxyfucoxathin and Zeaxathin. The maximum concentration of Chlorophyll b, Diadinoxathin and Fucoxathin were also found near the river mouth of Ming Jiay.
The distribution and abundance of phytoplankton were further reveal with community structure using CHEMTAX program with pigment measurements. The results indicated phytoplankton assemblages in this region. In coastal of Taiwan Strait, Diatom is the dominate plankton, but in the southern and eastern of Taiwan the main species were Cyanobateria. Pigment studies will be needed to clarify the driving forces for such unique variations.
