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.
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.
Multipurpose X-Band Marine Radar Network for the Minas Passage
January – November 2019
Marine X-band radar locates vessels and features, including coastlines and buoys. It filters distracting signals (eg.
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.
Integrated Active and Passive Acoustic System for Environmental Monitoring (ISEM)
August 2015 – May 2019
The project team will develop a novel environmental monitoring system that integrates data analysis software and active and passive acoustic sensors to provide real-time tracking of fish and marine mammals in high energy sites.
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.
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).
STREEM: Sensor Testing Research for Environmental Effects Monitoring
October 2018 – March 2019
The research goal was to enhance understanding on sensor performance and sensor-to-sensor interactions to inform environmental effects monitoring (EEM) protocol for future tidal turbine deployments.
Innovative Solutions for De-risking Species Detections in Tidal Energy Environmental Effects Monitoring Programs
April 2018 – March 2019
With collaboration from Genome Atlantic, this research project is using a new environmental DNA technology to rapidly identify and determine abundance of different fish species in high-flow marine conditions. Experiments were conducted at Dalhousie University’s Aquatron facility. N
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
