Vertical profiles of environmental parameters measured on discrete water samples collected with Niskin bottles at station TARA_012 during the Tara Oceans expedition 2009-2013
收藏资源简介:
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)是一场搭乘塔拉号帆船(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系统性测量,并采集了浮游生物(病毒、细菌、原生生物与后生动物)样本,用于后续借助现代测序与顶尖成像技术开展的分析研究。塔拉海洋数据集尤其适用于浮游生物的遗传、形态与功能多样性研究。 本次数据集涵盖了2009-2013年塔拉海洋科考航次中,利用尼斯金采水器(Niskin bottles)采集的离散海水样本所测得的海水、颗粒物与溶解物相关参数。 相关参数包括: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(表层与400米水深:总标度pH、二氧化碳(CO₂)、二氧化碳分压(pCO₂)、二氧化碳逸度(fCO₂)、碳酸氢根(HCO₃⁻)、碳酸根(CO₃²⁻)、总碱度、总碳、文石饱和度(OmegaAragonite)、方解石饱和度(OmegaCalcite),以及加注标记);营养盐参数(每垂直剖面设10个采样深度:亚硝酸盐(NO₂)、磷酸盐(PO₄)、亚硝酸盐/硝酸盐(NO₂/NO₃)、硅酸盐(SI),以及质量标记);溶解有机碳(DOC)、有色溶解有机物(CDOM)与溶解氧同位素。 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),通过电位滴定法测定了总无机碳(CT)与总碱度(AT)。 全球海域共完成了超200条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)与溶解氧同位素数据仅在2013年的北冰洋与北极海域航次中可获取。
