IODP Expedition 378 Interstitial water composite report

This composite report includes data from numerous interstitial water (IW) analyses (e.g., ICP-LIQUIDS and IONCHROM) in a variable set of columns. Each row combines the data from several tests (groups of measurements made on the same sample at the same time) for a particular IW sample. If data do not exist for a particular expedition, the column does not appear. To identify individual samples and tests, see each separate analysis (ALKALINITY, ICP-LIQUIDS, IONCHROM, SALINITY, SPEC, TITRATOR, and potentially others). Major and minor elements were determined by inductively coupled plasma-atomic emission spectrocsopy (ICP-LIQUIDS). Cations and anions were measured by ion chromatography (IONCHROM). Complex ions were measured by colorimetric measurements using a UV-VIS spectrometer (SPEC). Alkalinity and chloride was measured by titration (ALKALINITY and TITRATOR). Dissolved carbon (DC), dissolved inorganic carbon (DIC), and dissolved organic carbon (DOC) were measured by combustion in a total organic carbon (TOC) analyzer. Salinity was measured by refractometer (SALINITY). pH was measured by ion-selective electrode as part of the alkalinity procedure and is reported in the ALKALINITY analysis.本综合报告以列数可变的表格形式，收录了多组间隙水（interstitial water, IW）的分析数据，分析方法涵盖ICP-LIQUIDS、IONCHROM等。针对单一份间隙水样本，表格的每一行整合了该样本的多项测试数据——此处的测试指同一时间对同一样本开展的多组平行测量。若某一考察航次无对应分析数据，则该航次对应的列不会出现在表格中。若需识别单个样本与具体测试项，请查阅各独立分析报告，涵盖ALKALINITY、ICP-LIQUIDS、IONCHROM、SALINITY、SPEC、TITRATOR及其他潜在相关分析类型。常量与微量元素通过电感耦合等离子体原子发射光谱法（inductively coupled plasma-atomic emission spectroscopy, ICP-LIQUIDS）测定；阴阳离子通过离子色谱法（ion chromatography, IONCHROM）测定；络合离子采用紫外-可见分光光度计（UV-VIS spectrometer, SPEC）开展比色法测定；碱度与氯化物通过滴定法（ALKALINITY与TITRATOR）测定；溶解碳（dissolved carbon, DC）、溶解无机碳（dissolved inorganic carbon, DIC）与溶解有机碳（dissolved organic carbon, DOC）通过总有机碳（total organic carbon, TOC）分析仪燃烧法测定；盐度通过折射仪（SALINITY）测定；酸碱度（pH）作为碱度测试流程的一部分，通过离子选择性电极测定，相关结果收录于ALKALINITY分析报告中。
