An Aanderaa water level recorder was attached to mooring TG2, located in a lagoon of John Brewer Reef, away from the activities of fishing vessels. This tide gauge was placed near the reef to monitor any tidal differences between the reef and the adjacent deep water.Deployment Details:Date Deployed: 6/5/1987Date Recovered: 7/9/1987Instrument Deployed:Aanderaa WLR #W799Depth: Unknown 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. Tide gauges were placed at the corners of the model (moorings CM1, CM2, CM4 and TG1) and in the centre of the model, close to John Brewer Reef (TG2). The mooring CM1 drifted from its original position and only data up to the 27/5/87 are considered reliable. Mooring CM4 drifted to the Whitsunday Islands and the data were not considered reliable.
