Ocean drilling samples are recovered in cores, long tubes of material collected while drilling beneath the sea floor. Specific terminology is used to precisely describe the location of a sample taken in a core.
A sample identification number includes: leg, site, hole, core number, core type, section number, and interval in centimeters measured from the top of section. For example, “210-1276A-3R-3, 80–85 cm” is a sample from the interval 80 to 85 cm below the top of Section 3, Core 3R of Hole 1276A during Leg 210. All ODP core identifiers indicate core type (R = rotary core barrel, H = advanced piston corer, X = extended core barrel, and W = wash core).
Cored intervals can also be described in meters below sea floor (mbsf). The mbsf depth of a sample is determined by adding the depth of the sample below the section top and the lengths of all higher sections in the core to the core-top datum measured with the drill string.
