IODP Expedition 368 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.

本综合报告包含两类分析数据：采用CHNS元素分析（Elemental analysis）测得的总碳，以及采用库仑计（Coulometer）法测得的无机碳。每一行数据整合了针对特定层段及其偏移深度的同一样本，在同一轮测量中获取的对应检测数据。若特定科考航次无对应数据，则该数据列不会出现在报告中。如需识别单个样本及测试项，请参考各自独立的数据集类型：元素分析数据集与库仑计数据集。若同一样本通过任意一种方法多次测量，报告中将尽可能将结果合并至同一行；每额外一次平行检测结果将在后续行中展示，且同样尽可能进行合并。本报告涵盖以下碳形态的分析结果：总碳、无机碳、碳酸钙，以及通过差值计算得到的有机碳，同时包含总氢、总氮与总硫的测定结果。
