Grainsize of surface samples collected from the leeward, off-reef physiographic zone of Wistari Reef

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. Six surface samples were taken from the leeward, off-reef area and analysed to determine grainsize and the sorting coefficient (expressed as the standard deviation of grainsize) within each sample. The sediments of the leeward off-reef floor are relatively mature. Most samples are moderately well-sorted medium sand, and are moderately well-rounded. Patch reefs, and small individual colonial and solitary corals contribute a small amount of coarser material to the sediment.
