High Performance Liquid Chromatography (HPLC) pigment analysis from rosette bottle samples at various depths from CCE LTER process cruises in the California Current System, 2006 and 2008 (ongoing).

High Performance Liquid Chromatography (HPLC) samples are collected from rosette bottles (from three to eight different depths in the photic zone) at stations located within the CCE region on Process cruises (since 2006, ongoing). The HPLC method is used to measure concentrations of chlorophylls and carotenoids in samples of particulate matter, which includes filtering and freezing the filter while at sea. The taxon-specific phyto-pigments are extracted back onshore. Concentrations of chlorophyll a are used as a proxy for phytoplankton biomass and concentrations of other taxon-specific pigments are used to determine contributions of phytoplankton taxa to total phytoplankton biomass.

本数据集的分析采用高效液相色谱法（High Performance Liquid Chromatography, HPLC），样本采集自CCE区域内各测站的罗塞塔采水器，覆盖真光层3至8个不同深度的水样，相关采样工作依托Process航次开展，自2006年起持续进行。
该高效液相色谱法用于测定悬浮颗粒物样本中的叶绿素与类胡萝卜素浓度，采样现场需完成过滤操作并对滤膜进行低温封存。类群特异性浮游植物色素将运回岸基实验室完成萃取。
叶绿素a浓度可作为浮游植物生物量的替代指标，其余类群特异性色素浓度则用于确定不同浮游植物类群对总浮游植物生物量的贡献占比。
