A gravity core (GC10) was collected from a depth of 335 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The percentage of calcium carbonate in samples collected from different depths were analysed, along with other parameters, to determine changes in carbonate mineralogy and terrestrial influx. The results indicate that the minimums in CaCO3% precede the glacial maximums (at 130cm), then rapidly increase during deglaciations to reach a peak in CaCO3% of ~75% during the mid-interglacial.
