Determining the grainsize of sediment with increasing depth in core GC11, located in the Capricorn Channel

A gravity core (GC11) was collected from a depth of 502 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, and is particularly pronounced during glacial periods, at 460cm (MIS 10) and at 330cm (MIS 8).
