Ichthyolith counts (>38µm) and calculated ichthyolith accumulation rates determined in this study. Revised CCSF-A Depth Scale from: van Peer et al. 2017. Sediment dry bulk density was obtained from shipboard data (available from LIMS database) http://web.iodp.tamu.edu/LORE/?appl=LORE&reportName=mad&action=show&filters=[%22x_expedition%20in%20(%27342%27)%22,%22x_site%20in%20(%27U1406%27)%22].Ages based on shipboard magnetostratigraphy, see table S17 (this study, doi:10.1594/PANGAEA.910684) for more details.
