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

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.

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.

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.

Acceleration/Particle Velocity (PA/PV) Measurement System Evaluation in a Tidal Environment

February 2017 – December 2018

The objective of this project was designing and running a field experiment to test the performance of the Particle Acceleration/Particle Velocity (PA/PV) vector sensor.

Assessing Corrosion, Wear, Fatigue and VIV on Moorings and Cabling to Reduce Risk in Marine Operations

October 2017 – August 2018

The cost of cabling and moorings over the entire life of a tidal energy project is a significant proportion of total project expenditures and the potential failure of these components remains a major risk for the emerging tidal energy sector.

Measuring the Acoustic Detection Range of Large Whales from an Ocean Glider to Improve an Acoustic Whale Alert System for use by the Offshore Marine Industry in Atlantic Canada

April 2017 – January 2018

Researchers investigated a novel and in-development passive acoustic monitoring (PAM) system for use as a marine mammal detection technique. The work builds on a current research initiative between Dalhousie University and Woods Hole Oceanographic Institute (WHOI).
