The age with depth of core BAR9403 is calculated through 18O values, which are then correlated with the SPECMAP age-model. Based upon these measurements the age at the deepest part of the core (275cm) was calculated to be ~33,200yrs BP. The age vs. depth profile indicates a reasonably constant sedimentation rate, with an average deposition rate of ~8cm/1000yrs.
