Dataset: Quantifying the isotopic composition of oxygen and carbon with increasing depth in core GC12, located in the Capricorn Channel

Description

A gravity core (GC12) was collected from a depth of 990.5 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 ~170cm depth and MIS 4 at ~450cm corresponding to heavier 18-O values and other measured parameters.
