Core summary

Report includes detailed core data: drilling and coring depths, advancement, recovered core length measured on the catwalk and final curated length, core recovery, and sections cut.

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. Common types are F, H, R, X. Core types 1-9 indicate intervals drilled without coring.
    Top depth drilled DSF (m): depth below seafloor of beginning of drill string coring advancement.
    Bottom depth drilled DSF (m): depth below seafloor at end of drill string coring advancement.
    Advanced (m): advancement of drill string during coring or drilling.
    Recovered length (m): core length measured on the catwalk (sum of section lengths as observed on the catwalk).
    Curated length (m): final length determined by curator.
    Top depth cored CSF (m): depth below seafloor. Pinned to Top depth drilled DSF.
    Bottom depth recovered (m): depth below seafloor calculated from Core top depth and Curated length.
    Recovery (%): recovered length / advanced * 100 (for cored intervals only). Not reported for ghost cores, wash cores, or drilled intervals.
    Time on deck (UTC): time at which the driller observed the core on deck.
    Sections (no.): number of sections in the core.
    Label ID: automatically generated, human readable name for a core.
