Sediment depth is given in mbsf. Event numbers correspond to those presented in Takahashi et al. (2001, doi:10.2973/odp.proc.sr.180.152.2001). Two-way traveltimes of non-MCS events have had 18 ms added to move the event to the location corresponding to the point at which the first positive peak of a corresponding reflector would appear. The TWTT for each event has been added, in addition to the depth, age, and TWTT of key reflectors in the MCS data. Data are adapted from Takahashi et al. (2001, doi:10.2973/odp.proc.sr.180.152.2001).
