IODP Expedition 397 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.本综合报告收录了多组间隙水（interstitial water, IW）的分析数据（如ICP-LIQUIDS与IONCHROM），数据以可变列集的形式呈现；每一行整合了某一特定间隙水样品的多组测试数据，即同一时间对同一样品开展的一组测量值集合；若某一特定科考航次无对应数据，则其对应的列不会出现在报告中；如需识别单个样品与测试项目，请查阅各独立分析模块（ALKALINITY、ICP-LIQUIDS、IONCHROM、SALINITY、SPEC、TITRATOR及其他潜在模块）。常量与微量元素均通过电感耦合等离子体原子发射光谱法（ICP-LIQUIDS）测定，阴阳离子采用离子色谱法（IONCHROM）进行测定，络合离子则通过紫外-可见分光光度计（SPEC）开展比色法测定，碱度与氯化物通过滴定法（ALKALINITY、TITRATOR）测定，溶解碳（DC）、溶解无机碳（DIC）与溶解有机碳（DOC）均通过总有机碳（TOC）分析仪的燃烧法完成测定，盐度采用折射仪（SALINITY）测定，pH值作为碱度测试流程的一部分，采用离子选择性电极法测定，相关结果收录于ALKALINITY分析模块中。
