AB: An Acoustic Doppler Current Profiler, ADCP, was moored a few meters above the bottom at the 70 m isobath out from the Perth, Western Australia for a little over a year in 2000/2001. It recorded currents in 4 m depth bins every hour as well as the temperature at the instrument. The ADCP was put at the 70 m isobath so that it would come under the influence of both the wind-driven Capes Current in summer and perhaps incursions by the Leeuwin Current in all seasons. The record shows both these currents and is rich with the effects of other phenomena including upwelling, downwelling, sea/land breezes, summer and winter storms, and the passing of submesoscale eddies on the continental shelf. We discuss the ADCP data and complement them with satellite images, wind and sea level data.
