Dissolved Inorganic Carbon (DIC)

Interstitial water dissolved inorganic carbon volatilized as CO2 gas via sample acidification and measured by infrared absorption using an OI Analytical Aurora 1030C total organic carbon (TOC) analyzer.

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
    A/W: archive or working section half
    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.
    Dissolved inorganic carbon (mM): concentration of dissolved inorganic carbon.
    Timestamp (UTC): date and time the observation was made.
    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.
