HPLC and fluorometric derived phytoplankton pigment concentrations from seawater collected at the Bermuda Atlantic Time-series Study (BATS) site from October 1988 through June 2024

Data presented here contain HPLC derived phytoplankton pigments and fluorometric chlorophyll-a from the BATS site for October 1988 to June 2024. Samples are typically collected from 12 depths in the upper 250 meters of the water column where by 4l of seawater is filtered under low vacuum through a 25mm GF/F filter. The filter is then flash frozen in liquid nitrogen and stored at -80C. Shoreside, analysis is performed on a HPLC using a modified version of Wright et al., 1991 (modified by Dr R. Bidigare,University of Hawaii) which identifies the following pigments: Chlorophyll C3, Chlorophyll C2, Peridinin, 19’Butanoyloxyfucoxanthin, Fucoxanthin, 19’Hexanoyloxyfucoxanthin, Prasinoxanthin, Violoxanthin, Diadinoxanthin,, Alloxanthin, Diatoxanthin, Lutein, Zeaxanthin, Chlorophyll b, Chlorophyll a, Divinyl, chlorophyll_a, Alpha and beta carotene. Additionally, chlorophyll_A and phaeopigments are analyzed using a fluorometeric assay.
