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.
Development of High Performance Tidal Turbine Rotors
January 2013 – October 2015
This research investigated and informed novel and cost-effective engineering solutions to extract and deliver energy from tidal flows.
Turbulent Scale and Wake Modeling on a Horizontal Axis Turbine
January – April 2015
This project aimed to accurately simulate turbulent flow over a scaled horizontal axis tidal turbine to resolve turbulence in the near and far field regions.
Turbulence and Bottom Stress in Minas Passage and Grand Passage
September 2011 – February 2015
This project aimed to investigate turbulence and bottom stress at two sites being targeted for in-stream tidal power development in Nova Scotia: Minas Passage in the Upper Bay of Fundy and Grand Passage, located between Brier and Long Island in the lower Bay of Fundy.

Establishment of Baseline Biological Data on Snow Crab (Chionoecetes opilio) Offshore Cape Breton for Future Assessment of Potential Impacts of Seismic Noise on Snow Crab
April 2012 – February 2015
The study investigates the impact of sound energy generated by acoustic/seismic arrays on snow crabs.
Seasonal Erodibility of Sediment in the Upper Bay of Fundy
February 2012 – January 2015
This project developed methods for studying sedimentation to the macro-tidal flats of the upper Bay of Fundy. The researchers looked at seasonal variation in the erodibility of sediments in tidal creeks and flats using a Gust Erosion Chamber and repeated grain size surveys.
Testing of Temporal Monitoring Techniques for Benthic Habitat Impacts of Tidal Energy Developments
September 2011 – November 2014
This project tested and developed monitoring procedures for assessing the impact of the placement of in-stream tidal devices (e.g. turbines, cables and other seafloor hardware) on the seafloor environment.
Implications of Tidal Energy Extraction on Sedimentary Processes within Shallow Intertidal Environments
September 2011 – April 2014
This project assessed the implications of tidal energy extraction on sedimentary processes within shallow inter-tidal ecosystems.

Test Snow Crab Response to Seismic Stress
February 2012 – September 2013
There is concern in Atlantic Canada that there is insufficient information on the potential effects of seismic noise on snow crab.
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.
