This updated age model for ODP Site 1233 is based on the age model of Kaiser et al. 2005 (doi:10.1029/2005PA001146), derived from correlation with core GeoB 3313-1, mixed planktonic 14C ages from Lamy et al. 2004 (DOI: 10.1126/science.1097863) and correlation with Byrd. The update applies the MARINE13 calibration and regional reservoir corrections based on Siani et al. 2013 (DOI: 10.1038/ncomms3758).
