The age with depth of core MD032607 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 (3270cm) is ~176,590yrs BP. The age vs. depth profile for this core indicates a major increase in the sedimentation rate during the initial phase of MIS 6, when the sedimentation rate is ~41cm/1000yrs. The average sedimentation rate over the length of the core is 18.7cm/1000yrs.
