Brief description
A gravity core (GC12) was collected from a depth of 990.5 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The 18-O values of the different foraminiferal species down the depth of the core show relatively consistent inter-species offsets throughout the glacial and interglacial periods. This provides us with confidence that the 5 individual species presumably remained within the same water mass. Because each foraminifera species fractionate carbon and oxygen isotopes differently, amended 18-O values are given whenever possible to account for these well-known biological vital effects. Comparison of the 18-O values with SPECMAP (Martinson et al., 1987) provides us with a chronology for core GC12.Lineage

The analysis of stable isotopes in multiple species of planktonic foraminifera provides an insight into changes in the gradients of physical and biological properties in the water column.
