This report briefly summarizes results from a measurement campaign carried out in June 2018 at the southern entrance to Grand Passage, NS. The goals of the experiment were:

• To investigate wave/current/turbulence interactions using bottom-mounted 5-beam acoustic Doppler current profilers (ADCPs)
• To incorporate a gimballed ADCP mount in the bottom pods so that the ADCP would maintain a vertical orientation independent of the orientation of the pod once deployed on the rough and irregular seabed in the passage

This project is part of on-going research into remote measurements of turbulence in high-flow, well-mixed tidal channels using new generation ADCP techniques. This research will lead to improved measurements and validation of algorithms for estimating turbulence in the presence of surface gravity waves.
