The hydrodynamic regime at John Brewer Reef, Great Barrier Reef: Mooring CM7: Current Meter

An Aanderaa RCM current meter was attached to mooring CM7, which was deployed in 47m of water. Deployment Details:Date Deployed: 31/3/1987Date Recovered: 5/10/1987Instrument Deployed:RCM #5295; Depth: 25m The aim of this project was to collect field data to calibrate a numerical model for the combined tidal and wind-forced circulation at John Brewer Reef, and to apply those circulation patterns to calculate the trajectories, residence times and likelihood of outbreaks of crown-of-thorns starfish on areas of the reef. The locations for moorings CM6, CM7, CM8 and CM12 were chosen on the basis of results from a complementary project, where numerical models of hydrodynamics and dispersion were used to simulate the wind, tidal, long-period current and wave circulation around GBR reefs, for examination of dispersal of larvae of the crown-of-thorns starfish.
