How Does Sound Travel in High Energy Environments? Effectiveness of Acoustic Monitoring Systems and Turbine Audibility Assessment
April 2017 – December 2020
The researchers are designing and implementing a long-term acoustic monitoring program to support tidal energy development in the Bay of Fundy. Specialized acoustic instrumentation was deployed for a two-month period in Grand Passage to advance understanding how turbulence affects the ability to
Reducing Costs of Tidal Energy through a Comprehensive Characterization of Turbulence in Minas Passage
October 2017 – March 2020
Turbulence is a significant issue at every site being considered for in-stream tidal energy development.
Advancements in technologies and techniques for tidal energy development
April 2017 – March 2020
This project was funded under the Natural Resources Canada Energy Innovation Program and supported research into innovative technologies and techniques to advance the tidal energy sector. The research was comprised of five unique research initiatives with focus areas in environmental mo
Integrating Hydro-acoustic Approaches to Predict Fish Interactions with In-Stream Tidal Turbines
October 2017 – December 2019
Understanding exactly how fish interact with tidal turbines is still a critical knowledge gap for the tidal energy sector.
Quantifying Fish-Turbine Interactions Using New VEMCO Tagging Technology
October 2017 – December 2019
This project tested innovative acoustic fish tagging technology made by VEMCO, a Nova Scotian engineering technology company. Their acoustic telemetry tags are expected to be more effective in noisy, high-current environments like the Minas Passage.
Developing Enhanced Marine Operations (DEMO) in High Flow Tidal Environments
October 2017 – October 2019
Conventional subsea remotely operated vehicles (ROVs) perform poorly in currents exceeding 1.5 m/s. This is a key operating limitation in the success and cost of marine operations in the Bay of Fundy, where current speeds reach 5 m/s.
Application of (Low-Cost) Drifters with Suspended Hydrophone Arrays to Assess Harbour Porpoise Use of the Water Column and Spatial Overlap with MRE Devices in the Minas Passage
October 2017 – April 2019
The project investigated the use of a new low-cost drifter technology to monitor the activity and depth distribution of harbour porpoises frequenting the Minas Passage and Minas Channel.
Turbine Wake Characterization
November 2017 – March 2019
Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays. In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings. It is thus desired to not just delineate wake
Quantifying Demographics and Monitoring Movement of American Lobster in the Minas Passage and Basin
October 2017 – March 2019
The project consists of lobster fishing in Minas Passage during the fall lobster season to collect, assess and tag lobsters in this area, then fishing in Minas Basin from April to May to assess the spawning characteristics of lobster tagged the previous fall, then returning to Minas Passage to fi
Real-Time, Targeted Imaging of Turbine-Marine Life Interactions
March 2017 – February 2019
The research goal is to redesign and validate a dynamic mount to improve targeted real-time imaging of marine life in the near-field zone of a tidal turbine. The adjustable mount will enable imaging sensors to be aimed directly facing the tidal turbine.
