Vertical profiles of environmental parameters measured on discrete water samples collected with Niskin bottles at station TARA_161 during the Tara Oceans expedition 2009-2013

The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).塔拉海洋科考航次（2009-2013）是一场依托塔拉号帆船（"Sailing Vessel Tara"）开展的全球海洋生态系统调查。该航次完成了大范围的海洋环境参数测量，并采集了浮游生物（包括病毒、细菌、原生生物以及后生动物）样本，以供后续借助现代测序技术与顶尖成像手段开展分析研究。塔拉海洋数据集尤其适用于探究浮游生物的遗传、形态与功能多样性。本数据集涵盖2009-2013年塔拉海洋科考航次期间，通过尼斯金采水器（"Niskin bottles"）采集的离散水样所测得的海水、颗粒物及溶解物相关参数。相关参数包括：经高效液相色谱（"High Performance Liquid Chromatography, HPLC"）分析得到的色素浓度（每个垂直剖面设置10个采样深度，每个深度检测25种色素）；碳酸盐体系参数（覆盖表层与400米水深，包含pH（总标度）、CO₂、pCO₂、fCO₂、HCO₃⁻、CO₃²⁻、总碱度、总碳、文石饱和度、方解石饱和度及质控标识）；营养盐参数（每个垂直剖面设置10个采样深度，包含亚硝酸盐（NO₂）、磷酸盐（PO₄）、亚硝酸盐/硝酸盐（NO₂/NO₃）、硅酸盐（SI）及质控标识）；溶解有机碳（DOC）、有色溶解有机物（CDOM）以及溶解氧同位素。皮埃尔与玛丽·居里大学（"Université Pierre et Marie Curie"）下属的海洋二氧化碳参数国家分析服务中心采用电位滴定法测定了CT与AT参数。全球海洋范围内共完成了超200组上述参数的垂直剖面测量。溶解有机碳（DOC）、有色溶解有机物（CDOM）以及溶解氧同位素仅在2013年的北冰洋与北极海域的采样数据中提供。
