Quantifying the isotopic composition of oxygen and carbon with increasing depth in core GC10, located in the Capricorn Channel

Oxygène Biomasse et diversité microbienne

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.
