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.

Turbulence Dissipation Rates from Horizontal Velocity Profiles at Mid-Depth in Fast Tidal Flows

December 2017

This study characterizes the turbulence in a tidal channel in the Bay of Fundy that has been identified for development as a tidal power resource.

Finite Element Analysis to Assess Fish Mortality from Interactions with Tidal Turbine Blades

February – December 2017

The research project used finite element analysis (FEA) to simulate the impact of a tidal turbine blade on fish, and assess whether mortality of marine life can be expected in such an event.

High-Resolution Numerical Model Resource Assessment of Minas Passage, Bay of Fundy

January 2017

Two numerical models developed by the Acadia Tidal Energy Institute are described. The models simulate the tidal flow in the Bay of Fundy, and in particular the Minas Passage. The models have different grid resolution, one suitable for site assessment and one suitable for resource assessment.

Investigation of the Vertical Distribution, Movement and Abundance of Fish in the Vicinity of Proposed Tidal Power Energy Conversion Devices

March 2010 – December 2014

This project studied active fish avoidance of a turbine using the Coda Octopus Echoscope II 3-D multi-beam sonar mounted on a bottom platform. The objective was to observe and quantify the distribution and abundance of fish in the water column and their ability to detect and avoid turbines. 

Atlantic Sturgeon Spatial and Temporal Distribution in Minas Passage, Nova Scotia, Canada, a Region of Future Tidal Energy Extraction

January 2010 – January 2014

In the Bay of Fundy, Atlantic sturgeon from endangered and threatened populations in the USA and Canada migrate through Minas Passage to enter and leave Minas Basin.

Acoustic Tracking of Fish Movements in the Minas Passage and FORCE Crown Lease Area: Pre-Turbine Baseline Studies

June 2011 – July 2013

This project used animal tracking technology developed by VEMCO, a division of AMIRIX Systems of Halifax, NS. The technology allows researchers to track animal movements and behaviour over a scale of kilometers.

Passive Acoustic Monitoring of Cetacean Activity Patterns and Movements Pre- and Post-deployment of TISEC devices in Minas Passage

June 2011 – July 2013

This project aimed to conduct pre- and post- in-stream tidal energy device deployment assessments of marine mammal activity and to assess the potential risk for interaction with turbine infrastructure.

Cross Coupling between Device Level CFD and Oceanographic Models Applied to Multiple TISECs in Minas Passage

October 2011 – January 2013

This project aimed to develop a link between oceanographic computer models and Computational Fluid Dynamics (CFD) models in order to improve state-of-the-art modelling techniques used for resource assessments and tidal turbine siting for both single and multiple in-stream tidal energy devices.
