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).

Advanced Coastal Mapping to Support Hydrodynamic Modelling
April 2016 – June 2018
Nova Scotia’s Atlantic coast exhibits a variety of shorelines that may be vulnerable to contamination in the event of an offshore oil spill. In turn, variable currents, changing water levels, shoals, and exposed seaside conditions make effective spill response difficult for tidal inlets.
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.
Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power
August 2013
Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy.

Physics of the Interaction between a Crab and a Seismic Test Pulse – Development of a Mathematical Model and Testing of Model via Simulation
June 2009 – September 2011
Experimental attempts to establish whether seismic testing has any impact on crabs and the crab fishery have been hampered by a lack of theoretical work on the subject.
Assessment of the Potential of Tidal Power from Minas Passage and Minas Basin
October 2009 – September 2011
This project estimated the power potential of the tides and tidal currents in the Minas Basin and Minas Channel regions of the Bay of Fundy.
Nova Scotia Tidal In-Stream Energy Conversion (TISEC): Survey and Characterization of Potential Project Sites
October 2006
This study produced system designs for in-stream tidal energy devices, performance estimates, cost estimates and economic assessments for one site/device per state/province.
