Vertical profiles of environmental parameters measured on discrete water samples collected with Niskin bottles at station TARA_091 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（Tara Oceans Expedition，2009-2013）是依托风帆科考船“塔拉号”开展的全球海洋生态系统综合调查。该航次对海洋环境条件开展了全方位测量，并采集了浮游生物（病毒、细菌、原生生物与后生动物）样本，后续将借助现代测序技术与前沿成像技术对样本进行分析。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中，通过尼斯金采水器（Niskin bottles）采集的离散水样所测得的海水、颗粒物与溶解物相关参数。相关参数包括：经高效液相色谱（HPLC）分析得到的色素浓度（每个垂直剖面设置10个采样深度，每个深度测定25种色素）；碳酸盐体系参数（表层与400米深度：总尺度pH、CO₂、pCO₂、fCO₂、HCO₃⁻、CO₃²⁻、总碱度、总碳、文石饱和度、方解石饱和度，以及剂量标记位）；营养盐参数（每个垂直剖面设置10个采样深度：NO₂、PO₄、NO₂/NO₃、硅酸盐（SI）、质量标记位）；溶解有机碳（DOC）、有色溶解有机物（CDOM）以及溶解氧同位素。由皮埃尔和玛丽·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（Service National d'Analyse des Paramètres Océaniques du CO2）采用电位滴定法测定了总碳（CT）与总碱度（AT）。全球海域共完成了超过200组上述参数的垂直剖面测量。其中溶解有机碳、有色溶解有机物与溶解氧同位素仅在2013年的北冰洋与北极海域采样中可获取。
