Comment:
This updated age model for ODP Site 1234 is based on the planktonic foraminiferal ages published in Muratli et al. 2010 (doi:10.1038/ngeo715), and supplemented here by new benthic dates, all re-calibrated using INTCAL 7.0 MARINE13, plus a regional reservoir correction based on Siani et al. 2013 (DOI: 10.1038/ncomms3758).
Depth is given in meters composite depth.
