CTD seawater dissolved inorganic carbon and total alkalinity for R/V Sonne cruise SO289.

This dataset contains 395 measurements (all from the CTD rosette) of seawater dissolved inorganic carbon (DIC) and total alkalinity (TA) from the South Pacific Ocean. The samples were collected during R/V Sonne cruise SO289 in February-April 2022, as part of the GEOTRACES GP21 research programme to build an understanding of the distribution, origins, and depletions of trace elements and their isotopes (TEIs) in a lesser-explored ocean region. Measurements for TA and DIC were carried out using a VINDTA 3C instrument (#014, Marianda, Germany). All analysis was conducted at the NIOZ Royal Netherlands Institute for Sea Research. Bad results from technical issues during analysis have been removed from these results, so there are no recognised issues. The NIOZ created the metadata entry and is responsible for holding master copies of the data.

本数据集包含395项测量数据，全部采自南太平洋海域的CTD采水阵列（CTD rosette），测量对象为海水溶解无机碳（dissolved inorganic carbon, DIC）与总碱度（total alkalinity, TA）。样本采集工作于2022年2月至4月期间，在“松恩号”（R/V Sonne）科考航次SO289中完成，该工作隶属于全球海洋痕量元素及其同位素研究计划（GEOTRACES）GP21，旨在解析痕量元素及其同位素（trace elements and their isotopes, TEIs）在这片鲜有研究的海域中的分布特征、来源与耗竭机制。总碱度与溶解无机碳的测量采用德国Marianda公司生产的VINDTA 3C型分析仪（编号：014）完成，全部分析流程均在荷兰皇家海洋研究所（Royal Netherlands Institute for Sea Research, NIOZ）开展。分析过程中因技术故障产生的不合格结果已被剔除，因此本数据集无已知异常数据。荷兰皇家海洋研究所负责编制本数据集的元数据条目，并保管数据的主副本。
