The age model was derived from a combination of an astronomical age model based on orbital tuning for the time interval between 6 to 2.5 Ma (Tiedemann et al., 2007, doi:10.2973/odp.proc.sr.202.210.2007) and the combined foraminiferal and nannofossil biostratigraphy from 0 to 2.5 Ma (Shipboard Scientific Party, 2003, doi:10.2973/odp.proc.ir.202.112.2003) updated with a new nannofossil biostratigraphy for the time interval 0 to 2.5 Ma (Flores et al., 2006, doi:10.2973/odp.proc.sr.202.214.2006). All of the biostratigraphic ages were adjusted to the 2004 timescale (Lourens, 2004, doi:10.1029/2003PA000997)
