Calibration of calendar years was based on a Bayesian age modeling approach (Ramsey, 2009) using the Marine20 database (Heaton et al., 2020). Depth of individual samples is given as core depth below sea floor (CSF-A) and core composite depth below sea floor (CCSF-A), as defined by the IODP Depth Scale Terminology (IODP-MI 2011). Calendar ages are represented by the lower and upper boundary of the highest density region
