Comment:
Depth, sediment (m) is meters composite depth (mcd), a common depth below sediment surface is assigned to samples from neighboring drilling sites in order to be able to directly compare them (Rea et al., 1998, doi:10.1029/98PA00123). AGE is the stratigraphic age of the samples after Rea et al. (1998)
