Dataset: Parent record: Datasets relating to core GC-09, located in the Capricorn Channel at a depth of 166 mbsl.


Description

Core GC09 (22o53' 70S 152o38' 10E) was collected from the Capricorn Channel at a depth of 166 mbsl (metres below sea level). By investigating the properties and components of this core we are able to reveal some information about this hemi-pelagic sedimentary environment over the last glacial / interglacial cycle. Information obtained or inferred from the core include the isotopic composition of oxygen and carbon through time, the percentage of grainsize fractions throughout the core and the percentage of carbonate material in each sample. X-ray Diffraction (XRD) analyses were also run on several samples from each core to determine changes in the carbonate mineralogy and terrestrial influx, which provided further palaeoclimatic information.
