Definition

CSFA

Core depth below seafloor

Meters below seafloor (mbsf)

Initial drilling depth.

CCSFA

Core composite depth below seafloor, appended

Meters composite depth (mcd)

Composite depth scale in which cores from all holes are aligned by adding an affine value specific to each core.

CCSFD

Splice

Splice

Composite sequence representing the complete stratigraphy at a site. It is composed of core sections from adjacent holes such that coring gaps or sampling gaps in one hole are filled with sediment from an adjacent hole.

CCSFB

Corrected composite depth scale


Corrects for the affine growth and is the same length as the total depth cored. It is constructed by applying the specific equations determined for various depth intervals at each site.
