Notes: Ages updated from Lyle, Koizumi, Richter, et al. (1997) for all sites except Site 1015; see text for references. mbsl = meters below sea level; mbsf = meters below seafloor; mcd = meters composite depth (from spliced continuous section). * = the basin sill depths for California Borderland basins are in [ ] and give the effective water depth for the sites for studies of water column structure. † = there is one minor break in the continuous record at 108 mbsf (119 mcd). ‡ = there is a hiatus at the top of Site 1022 from 0 to 2.3 Ma. — = no paleomagnetic data.
