IODP Expedition 359 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）分析数据，涵盖可变列数的数据集，分析方法包括电感耦合等离子体液体分析（ICP-LIQUIDS）与离子色谱分析（IONCHROM）等。数据集中每一行对应某一特定间隙水样品的多次测试结果，即同一时间对同一样品开展的多组测量的汇总数据。若某一航次无对应分析数据，则其对应的列不会出现在数据集中。如需识别单个样品及测试详情，请参阅各独立分析项：碱度分析（ALKALINITY）、电感耦合等离子体液体分析（ICP-LIQUIDS）、离子色谱分析（IONCHROM）、盐度分析（SALINITY）、紫外-可见分光光度法（SPEC）、滴定仪分析（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（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-可见分光光度计（SPEC）开展比色法检测；碱度与氯离子通过滴定法测定，对应分析项为ALKALINITY与TITRATOR；溶解碳（DC）、溶解无机碳（DIC）与溶解有机碳（DOC）通过总有机碳（TOC）分析仪的燃烧法完成检测；盐度通过折射仪（SALINITY）测定；pH值作为碱度分析流程的一部分，采用离子选择性电极法测得，结果收录于ALKALINITY分析项中。
