Pigment concentration database of the sea surface layer collected during the Tara Pacific Expedition 2016-2018

The Tara Pacific expedition (2016-2018) sampled coral ecosystems around 32 islands in the Pacific Ocean, and sampled the surface of oceanic waters at 249 locations, resulting in the collection of nearly 58,000 samples. The expedition was designed to systematically study corals, fish, plankton, and seawater, and included the collection of samples for advanced biogeochemical, molecular, and imaging analysis. Here we provide a pigment concentrations database originating from 545 stations sampled during the expedition. Pigment were measured by High Performance Liquid Chromatography. This pigment database provides high quality measurements of the major taxonomic 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.

塔拉太平洋科考航次（Tara Pacific expedition，2016-2018年）对太平洋32座岛屿周边的珊瑚生态系统及249个站位的表层海水开展采样工作，累计收集近58000份样品。本航次旨在系统性研究珊瑚、鱼类、浮游生物与海水，同时采集了可用于高级生物地球化学、分子生物学及成像分析的样品。本数据集包含该航次545个站位采集样品的色素浓度数据库，色素浓度通过高效液相色谱法（High Performance Liquid Chromatography）完成测定。本色素数据库提供了主要分类学色素的高精度检测数据，涵盖叶绿素a（chlorophyll a）、叶绿素b（chlorophyll b）、叶绿素c（chlorophyll c）、多甲藻素（peridinin）、19'-丁酰氧基岩藻黄素（19'-butanoyloxyfucoxanthin）、岩藻黄素（fucoxanthin）、新黄素（neoxanthin）、绿藻黄素（prasinoxanthin）、紫黄素（violaxanthin）、19'-己酰氧基岩藻黄素（19'-hexanoyloxyfucoxanthin）、双甲藻黄素（diadinoxanthin）、花药黄素（antheraxanthin）、别黄素（alloxanthin）、双脱甲藻黄素（diatoxanthin）、玉米黄质（zeaxanthin）、叶黄素（lutein）、二乙烯基叶绿素b（divinyl chlorophyll b）、叶绿素b、二乙烯基叶绿素a（divinyl chlorophyll a）、叶绿素a、胡萝卜素（carotene）以及细菌叶绿素a（bacteriochlorophyll a），上述数据可用于估算浮游植物群落组成。
