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

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

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.

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.

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.

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.

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
