IODP Expedition 395 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，分析手段涵盖液相电感耦合等离子体发射光谱法（ICP-LIQUIDS）与离子色谱法（IONCHROM）等，涉及多组可变列。报告中每一行对应某一特定间隙水样品的多项测试数据，即同一时段对同一样品开展的多组测量结果的集合。若某次科考航次无对应检测数据，则其对应列不会出现在报告中。如需识别单个样品及测试详情，请参阅各项独立分析报告，包括碱度（ALKALINITY）、液相电感耦合等离子体发射光谱法（ICP-LIQUIDS）、离子色谱法（IONCHROM）、盐度（SALINITY）、紫外-可见分光光度法（SPEC）、滴定法（TITRATOR）及其他潜在分析项目。常量与微量元素通过液相电感耦合等离子体发射光谱法（ICP-LIQUIDS）测定；阳离子与阴离子通过离子色谱法（IONCHROM）测定；络合离子采用紫外-可见（UV-VIS）分光光度计开展比色法检测（对应方法缩写为SPEC）；碱度与氯离子通过滴定法测定（对应方法缩写分别为ALKALINITY与TITRATOR）；溶解碳（DC）、溶解无机碳（DIC）及溶解有机碳（DOC）通过总有机碳（TOC）分析仪经燃烧法完成测定；盐度通过折射仪测定（SALINITY）；pH值作为碱度测试流程的组成部分，采用离子选择性电极进行检测，相关结果收录于ALKALINITY分析报告中。
