IODP Expedition 355 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.

本复合报告包含多组间隙水（interstitial water, IW）分析数据（如ICP-LIQUIDS与IONCHROM），采用列数可变的表格结构。每一行整合了某一特定间隙水样品的多次测试数据——此处测试指同一时间对同一样品开展的一组测量操作。若某一科考航次无对应数据，则该列不会出现在报告中。如需识别单个样品与测试项，请查阅各独立分析报告，包括碱度（ALKALINITY）、ICP-LIQUIDS、IONCHROM、SALINITY、SPEC、TITRATOR及其他潜在分析项。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（IONCHROM）测定。络离子通过紫外-可见分光光度计（UV-VIS spectrometer, SPEC）开展比色测定。碱度与氯化物通过滴定法（ALKALINITY与TITRATOR）测定。溶解碳（DC）、溶解无机碳（DIC）与溶解有机碳（DOC）通过总有机碳（total organic carbon, TOC）分析仪的燃烧法完成测定。盐度通过折射仪（SALINITY）测定。pH值作为碱度测试流程的一部分，通过离子选择性电极法测定，并在ALKALINITY分析报告中予以记录。
