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.

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.

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.

Advanced Analyses of the MIRROR-1 OBS Profile from Offshore Morocco

July 2017 – April 2019

This project completes an analysis of the OETR and OCTOPUS seismic lines collected from offshore Nova Scotia and integrates the MIRROR I refraction line from offshore Morocco to allow comparison of the conjugate margins using wide-angle refraction/reflection ocean bottom seismometer profiles.

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.

FORCE Site Marine Operations – Lessons Learned

November 2017 – April 2018

In recent years, marine operators have completed dozens of operations in the Minas Passage, from research surveys to instrument deployment, to the installation of electrical infrastructure to turbine deployment.

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).

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.
