Pigment concentrations derived from High-Performance Liquid Chromatography (HPLC) analysis from samples collected during the Tara Pacific expedition from 2016-2018

The Tara Pacific expedition (2016-2018) sampled coral ecosystems around 32 islands in the Pacific Ocean. Here we provide pigment concentration data originating from 545 stations that were sampled during the expedition in the Pacific and during transit across the Atlantic. Pigment concentrations were derived from High-Performance Liquid Chromatography (HPLC) analysis. This data set provides high-quality measurements of major pigments including chlorophylls a, b, and c, peridinin, 19'-butanoyloxyfucoxanthin, fucoxanthin, neoxanthin, prasinoxanthin, violaxanthin, 19'-hexanoyloxyfucoxanthin, diadinoxanthin, antheraxanthin, alloxanthin, diatoxanthin, zeaxanthin, lutein, divinyl chlorophyll b, chlorophyll b, divinyl chlorophyll a, chlorophyll a, carotene, and bacteriochlorophyll a, which can be used to estimate phytoplankton community composition.
