Three Methods to Measure Ocean Currents

For presentation at the 17th International Conference on Coastal Engineering, Sydney, Australia, March 23-28, 1980

Ocean currents were measured over a twelve month period offshore from Black Rock, Victoria, as part of a study for a future ocean outfall. Three methods were used to measure currents; (1) free floating drogues; (2) tethered drogues and (3) moored current meters. When averaged over the year, each method indicated the same general distributions of current speeds and directions. However, each method provides a different representation of the current pattern and their collective use leads to a better understanding of the currents than would be obtained by using any one method by itself.
