IODP Expedition 401 Carbonates composite report

This composite report includes data from two analyses (total carbon from Elemental analysis [CHNS], and inorganic carbon from [Coulometer]). Each row combines the CHNS and Coulometer data from measurements made on the same sample at the same time for a particular section and section offset (depth). If data do not exist for a particular expedition, the column does not appear. To identify individual samples and tests, see each separate data type (Elemental analysis and Coulometer). If the same sample was measured multiple times by any of the methods, results in the report will be combined on one line where possible. Each additional replicate result will be shown in subsequent rows and will be combined where possible. Report includes results for carbon forms: total, inorganic, calcium carbonate, and organic by difference, along with total hydrogen, nitrogen, and sulfur.本综合报告涵盖两类分析的检测数据：分别为元素分析（Elemental analysis，CHNS）得到的总碳，以及库仑法（Coulometer）测定的无机碳。每一行数据均对应同一特定剖面及剖面偏移量（深度）下的同一样本，同时整合了该样本同期开展的CHNS与库仑法检测结果。若特定考察航次无对应检测数据，则该数据列不会在报告中呈现。若需识别单个样本与检测项目，请查阅两类独立数据类型的说明：元素分析与库仑法检测。若同一样本通过任意一种检测方法进行了多次重复测量，报告将尽可能将其结果合并至同一行中。每新增一组重复检测结果，将依次展示于后续行中，并尽可能进行合并处理。本报告涵盖各类碳形态的检测结果：总碳、无机碳、碳酸钙，以及通过差值法计算得到的有机碳，同时包含总氢、总氮与总硫的测定结果。
