Water level variations along the outer Great Barrier Reef (1985-1988)

Tide Gauges were deployed at 6 stations along the outer Great Barrier Reef (Harrington Reef, Raine Island, Creech Reef, Reef No. 17-065, Reef No. 19-151 and Gannet Cay) and 2 stations in the Coral Sea (Willis Island and Flinders Cay). Sea level measurements along the outer Great Barrier Reef allow improved forcing and validation of hydrodynamic models. The presence of outer shelf reef platforms allow these observations to be made economically. Long term tidal height analysis also improves long term sea level predictions. Appropriately paired gauges with coastal or Coral Sea reefs can provide an estimate of geostrophic currents and a proxy for the EAC.

潮位计（Tide Gauges）分别部署在大堡礁外缘的6个站点（哈灵顿礁、雷恩岛、克里奇礁、17-065号礁、19-151号礁与甘尼特礁屿）以及珊瑚海的2个站点（威利斯岛与弗林德斯礁屿）。沿大堡礁外缘开展的海平面测量，可优化水动力模型的强迫项并提升其验证效果。外陆架礁体平台的存在使得此类观测具备经济可行性。长期潮位分析亦可改善长期海平面预报的精度。对沿海或珊瑚海礁体的潮位计进行合理配对，可估算地转流（geostrophic currents），并作为东澳海流（East Australian Current，EAC）的替代指标。
