Pigment Concentrations Measured by HPLC Method and Fluoremetric Method during the U.S. JGOFS Arabian Sea Process Study

In addition, on two of the cruises (TTN-049 and TTN-053), underway fluorescence was measured along the ship's track. With the HPLC method, concentrations of the following pigments were measured from the water samples taken at various depths: chlorophyll a, chlorophyll b, chlorophyll c3, chlorophyllide a, peridinin, fucoxanthin, prasinoxanthin, violaxanthin, diadinoxanthin, alloxanthin, diatoxanthin, zeaxanthin, neoxanthin, lutein, alpha carotene, beta carotene.

(Data collected by R. Bidigare or R. Goericke.) With the fluorometric method, concentrations of chlorphyll a and phaeopigments were measured from the water samples taken at various depths. (Data collected by R. Bidigare.) Underway fluorescence was measured by fluorometer every minute along ship track during cruise TTN-049 and every four minutes along ship track during cruise TTN-053. Chlorophyll concentrations are given.
