Brief description
A gravity core (GC10) was collected from a depth of 335 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The data from stable isotopes of Globigerinoides ruber were analysed to allow a preliminary understanding of the hemipelagic sedimentary environment over the last glacial / interglacial cycle. The results suggest that the core reaches the Last Glacial Maximum (LGM) at ~130cm depth, corresponding to isotopically heavier 18O. The 13C appears to lag the 18O signal with the minimums just proceeding the glacial maximums in the 18O.Lineage
Maintenance and Update Frequency: notPlannedParameters: Depth in core (cm), oxygen-18 G. ruber (parts per thousand), carbon-13 G. ruber (parts per thousand).

To determine the sedimentological variations with sea-level over the last glacial / interglacial cycle in the Capricorn Channel. Very little previous work has been undertaken within this area.
