The Vectron2 Project: Turbulence Measurements for the In-stream Tidal Energy Industry

March 2019 – November 2021

The Vectron is a new sensor used for measuring turbulence velocity within a tidal turbine’s swept area.  The Vectron has been successfully prototyped, where next steps are to take the technology to the ‘industry-ready’ stage of development and the focus of this project.

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.

Turbulent Scale and Wake Modeling on a Horizontal Axis Turbine

January – April 2015

This project aimed to accurately simulate turbulent flow over a scaled horizontal axis tidal turbine to resolve turbulence in the near and far field regions.

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.

Establishment of Baseline Biological Data on Snow Crab (Chionoecetes opilio) Offshore Cape Breton for Future Assessment of Potential Impacts of Seismic Noise on Snow Crab

April 2012 – February 2015

The study investigates the impact of sound energy generated by acoustic/seismic arrays on snow crabs.

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.

Tidal Energy: Strategic Environmental Assessment – Bay of Fundy Update (Phase II)

January 2014

This is an update to the Phase 1 Strategic Environmental Assessment (SEA) of marine renewable energy in the Bay of Fundy, with an emphasis on tidal in‐stream turbines.
