Multi-Scale Turbulence Measurement in the Aquatron Laboratory
July 2018 – July 2019
This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.
Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions
April 2018 – April 2019
Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).
Drones and Drifters – The Great Pumpkin Race
October 2016 – July 2017
This project tested and developed a new low-cost approach to collecting oceanographic measurements for use in tidal initial site assessments. The plan combines one of the oldest tools in oceanography, the drifter, with one of the newest, the drone.
Turbulence in Grand Passage Nova Scotia: Measures of Intermittency
April – December 2016
Turbulence research is very important to advancing the in-stream tidal energy sector, however turbulence in general is not well understood. Measurement at prospective turbine locations is essential prior to development, given the high degree of spatial variability between sites.
Spectral and Structure Function Estimates of Turbulence Dissipation Rates in a High Flow Tidal Channel Using Broadband ADCPs
January 2016
Spectral and structure function methods are implemented to compute the dissipation rate, ε, from broadband, diverging-beam, acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal channel.
Impacts of Tidal Energy Extraction on Sediment Dynamics in Minas Basin, Bay of Fundy
February 2010 – December 2012
Researchers developed a numerical hydrodynamic and sediment transport model for Minas Basin in the Bay of Fundy, focusing on the sediment dynamics of the tidal inlets and flats.
Effects of Energy Extraction on Sediment Dynamics in Intertidal Ecosystems of the Minas Basin
January 2010 – May 2012
This project assessed how the dynamics of sedimentation change when energy is extracted from a macro-tidal system. The differences in tidal prism and energy between neap and spring tidal cycles were used as a proxy for energy extraction by in-stream tidal power devices.
Assessing the Far Field Effects of Tidal Power Extraction on the Bay of Fundy, Gulf of Maine and Scotian Shelf
January 2010 – April 2012
The Bay of Fundy and Gulf of Maine system has a natural resonant period very close to the main semi-diurnal lunar tide. This results in the world’s highest tides and strong tidal currents in the Bay of Fundy, particularly in the Minas Channel and Minas Basin.
Assessment of Hydrodynamic Impacts throughout the Bay of Fundy and Gulf of Maine due to Tidal Energy Extraction by Tidal Lagoons
January 2010 – December 2011
The researchers extended existing hydrodynamic models of tidal flows in the Bay of Fundy to simulate the presence and operation of a tidal lagoon project located in the Minas Basin.

Feasibility of a Marine Vibroseis System to Minimize Potential Impacts of Seismic Surveying on Commercial Marine Invertebrates
May 2010 – May 2011
Marine vibroseis (a sound generating system that uses a large oscillating mass to emit a range of frequencies) offers an alternative to air-gun seismic sources and may have fewer environmental effects on marine biota.
