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.
Advancing Tidal Energy Turbine Operations through High Fidelity Tug Propulsion and Control Simulation Software
November 2016 – March 2017
The project objective was to develop a numerical model of a tug boat and its propulsion system to accurately predict its dynamic behaviour in turbulent tidal flows.
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.
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.
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.
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.
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.
