Dataset: Mapping facial cavities on a lagoonal patch reef on Davies Reef, Great Barrier Reef


Systematic description of the surface character of the various reefal elements of lagoonal patch reefs is necessary to help resolve questions in regard to nutrient flow and general trophodynamics within these systems. Davies Reef, east of Townsville, was chosen as a study site to gather relevant background information.

Davies Reef consists of a south-easterly aspect, curved (kidney-shaped) coral barrier enclosing a shallow (about 10m deep) lagoon with many patch reefs (bommies), about 50m in diameter. A single, relatively small bommie (<30m diameter) was chosen for surface mapping. This study was carried out over four days (25-28 September, 1980).
