Whole-round Core Sections (WRLSC JPG)

This report provides access to digital whole-round core section images. These images were taken of the outer surface of whole-round cores before splitting, in four 90° segments, on the Section Half Imaging Logger (SHIL). The SHIL produces TIF files as well as reduced-size JPG files. The TIF files are only available on the ship; shore-based users may request them from the data librarian. A 360° composite image is also provided.

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 depth CSF-A (m): location of the upper edge of the section expressed relative to the top of the hole.
    Bottom depth CSF-A (m): location of the lower edge of the section expressed relative to the top of the hole.
    Top depth [other] (m): location of the upper edge of the section 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 section expressed relative to the top of the hole. The location is presented in a scale selected by the science party or the report user.
    360 (deg) composite image filename (JPG): JPG file of the 360 (deg) composite of the 4 quadrant whole-round core section images. The composite is manually created by the Imaging Specialists using Photoshop.
    Timestamp (UTC): point in time at which the 0° whole-round core section image was acquired. The remaining 3 quadrant images are taken in sequence within a few minutes. The composite 360° image is usually created within 12 hours.
    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.
