Comment:
Ages have been assigned using the relaxed hybrid CONOP model of Crampton et al. (2016). No biostratigraphic markers exist in the interval directly below 141.26 so the age model here assumes the same sedimentation rate as between 113.6 and 141.26.
Age tie points from 214.13 mbsf and above from: Acton et al. (2008). Age tie points from 214.14 to 1138.54 mbsf from Levy et al. (2016).
