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（2009-2013年）是一场搭乘风帆塔拉号（Sailing Vessel Tara）开展的全球海洋生态系统调查。该航次对海洋环境条件开展了全方位测量，并收集浮游生物（plankton，包含病毒、细菌、原生生物与后生动物）样本，用于后续借助现代测序技术与顶尖成像技术开展的分析。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，通过尼斯金采水瓶（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。具体包括高效液相色谱（HPLC）分析得到的色素浓度（每垂直剖面设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，涵盖总尺度pH、溶解二氧化碳CO₂、分压pCO₂、逸度fCO₂、碳酸氢根HCO₃⁻、碳酸根CO₃²⁻、总碱度、总碳、文石饱和度、方解石饱和度及剂量标记旗标）、营养盐参数（每垂直剖面设10个采样深度，涵盖亚硝酸盐NO₂⁻、磷酸盐PO₄³⁻、亚硝酸盐/硝酸盐NO₂⁻/NO₃⁻、硅酸盐SI及质量标记旗标），以及溶解有机碳（DOC）、有色溶解有机物（CDOM）与溶解氧同位素。
巴黎第六大学（Université Pierre et Marie Curie）的CO₂海洋参数国家分析实验室采用电位滴定法测定了总碳CT与总碱度AT。全球海洋范围内共完成超200条此类参数的垂直剖面测量。溶解有机碳、有色溶解有机物与溶解氧同位素数据仅在2013年采集的北冰洋与北极海域样本中可获取。
