Determining the grainsize of sediment with increasing depth in core GC10, located in the Capricorn Channel

A gravity core (GC10) was collected from a depth of 335 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. This assembly of information suggests that the core reaches the Last Glacial Maximum (LGM) at ~130cm depth. The smallest size fraction (<100µm) dominates at all depths, with the shallowest sample (5cm) exhibiting 93% of material within this size range.
