The hydrodynamic regime at John Brewer Reef, Great Barrier Reef: Mooring CM2: Current Meter

An Aanderaa RCM current meter was attached to mooring CM2, located south of John Brewer Reef and in the free stream. The mooring was deployed in 36m of water. Deployment Details:Date Deployed: 4/4/1987Date Recovered: 5/9/1987Instrument Deployed:RCM #6022; Depth: 18m
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 model boundary was defined by CM1, CM2, CM3, CM4, CM5 and CM13. However, the current meters attached to moorings CM5 (deployed 2/4/87) and CM13 (deployed 1/4/87) were not recovered. Mooring CM4 (deployed 2/4/87)drifted to the Whitsunday Islands. The current meter was badly fouled and the data were unusable.

一台安德拉（Aanderaa）RCM海流计被安装于锚系CM2之上，该锚系坐落于约翰布鲁尔礁（John Brewer Reef）以南的开阔流场中，布放水深为36米。布放详情：布放日期：1987年4月4日；回收日期：1987年5月9日；布放仪器：RCM #6022；安装深度：18米。
本项目旨在获取现场实测数据，以校准适用于约翰布鲁尔礁区域潮汐与风力共同驱动环流的数值模型，并依托该环流模式计算珊瑚礁海域长棘海星（crown-of-thorns starfish）的运移轨迹、滞留时间及暴发概率。
该数值模型的边界由CM1、CM2、CM3、CM4、CM5及CM13锚系共同定义。但锚系CM5（布放日期：1987年4月2日）与CM13（布放日期：1987年4月1日）搭载的海流计均未被回收；锚系CM4（布放日期：1987年4月2日）发生漂移，最终抵达圣灵群岛（Whitsunday Islands），其搭载的海流计严重污损，所获数据均无法使用。
