Mean grainsize of surface samples collected from the sanded reef flat physiographic zone of Wistari Reef

Updated: 2014-12-16

Wistari Reef is a lagoonal platform reef, situated on the Tropic of Capricorn, within the Capricorn and Bunker region of the southern Great Barrier Reef. Surface samples were taken from the sanded reef-flat to determine the mean grainsize and the sorting coefficient and also the proportion of aragonite to calcite within the samples. In this area the average mean grainsize is ~0.46phi, with an average sorting coefficient of 0.91phi.
