A gravity core (GC12) was collected from a depth of 990.5 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, with an average of 95% in this size bracket at the base of the core. A peak in the larger grainsize fraction at 490cm is the result of a pteropod layer within the sediments. These pteropod accumulations are regular features within the cores. The exact reason for their occurence is unknown.
