Dataset: Quantifying the isotopic composition of oxygen and carbon with increasing depth in core GC13, located in the Capricorn Channel


A gravity core (GC13) was collected from a depth of 1482 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 ~90cm depth and MIS 6 at ~340cm corresponding to heavier 18-O values and other measured parameters.
