IODP Expedition 376 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.

本综合报告收录多组孔隙水（interstitial water, IW）分析数据，涵盖电感耦合等离子体液体分析（ICP-LIQUIDS）、离子色谱（IONCHROM）等多种检测手段，涉及多组可变的数据列。每一行数据整合了针对某一特定孔隙水样品的多组平行测试结果——即同一时间对同一样品开展的多组测量数据的集合。若某次科考航次未获取对应数据，则该数据列不会出现在报告中。如需识别单个样品及测试批次，请参阅各独立分析报告：包括碱度分析（ALKALINITY）、ICP-LIQUIDS、离子色谱（IONCHROM）、盐度分析（SALINITY）、紫外-可见分光光度法（SPEC）、滴定仪（TITRATOR）及其他潜在分析项目。常量与微量元素通过电感耦合等离子体原子发射光谱法（ICP-LIQUIDS）测定；阳离子与阴离子通过离子色谱法（IONCHROM）测定；络合离子通过紫外-可见分光光度计（SPEC）开展比色法检测；碱度与氯离子通过滴定法（ALKALINITY、TITRATOR）测定；溶解碳（DC）、溶解无机碳（DIC）及溶解有机碳（DOC）通过总有机碳（TOC）分析仪燃烧法测定；盐度通过折射仪（SALINITY）测定；pH值作为碱度测试流程的一部分，采用离子选择电极法测得，相关结果收录于碱度分析报告中。
