Determining the grainsize of sediment with increasing depth in core GC14, located in the Capricorn Channel

A gravity core (GC14) was collected from a depth of 2004 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Samples were separated into different size fractions to determine the % of each grainsize at each sample depth. Although not overly accurate, the information is correlated with analyses of other parameters to impart clues to the environmental changes within the core. The smallest size fraction (<100µm) dominates at all depths. There are small peaks in the coarser grained material at the bottom of the core which relate to pteropod layers in the sediment.
