Salinity Salinity was measured on interstitial water (IW) samples using an optical refractometer. Data File format Exp: expedition number Site: site number Hole: hole number Core: core number Type: type indicates the coring tool used to recover the core (typical types are F, H, R, X). Sect: section number Top offset (cm): position of the upper edge of a piece, measured relative to the top of a section. Bottom offset (cm): position of the lower edge of a piece, measured relative to the top of a section. Top depth CSF-A (m): location of the upper edge of the sample expressed relative to the top of the hole. Bottom depth CSF-A (m): location of the lower edge of the sample expressed relative to the top of the hole. Top depth [other] (m): location of the upper edge of the sample expressed relative to the top of the hole. The location is presented in a scale selected by the science party or the report user. Bottom depth [other] (m): location of the lower edge of the sample expressed relative to the top of the hole. The location is presented in a scale selected by the science party or the report user. Salinity: salinity measured by refractometer (unitless). Timestamp (UTC): time file was uploaded, which is typically a few minutes to hours after data were acquired. Text ID: automatically generated unique database identifier for a sample, visible on printed labels. Test No: unique number associated with the instrument measurement steps that produced these data. Sample comments: observations recorded about the sample itself. Test comments: observations about a measurement or the measurement process; some measurement observations may be under Result comments. Result comments: observations about a measurement or the measurement process; some measurement observations may be under Test comments.
