A gravity core (GC13) was collected from a depth of 1482 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Isotopic values for 18-O and 13-C were obtained from Globigerinoides ruber and correlated with the SPECMAP age-model. The age-model that was produced plausibly extends back to Marine Isotope Stage (MIS) 6, with approximate sedimentation rates calculated according to this model. Sedimentation rates fluctuate from 5cm/kyr during the last transition and interglacial, to 1cm/kyr during the glacial maximum.
