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.

Assessing Marine Mammal Presence in and near the FORCE Crown Lease Area during Winter and Early Spring

October 2013 – February 2015

This study closes the winter/spring baseline data gap via deployments of multiple, calibrated C-PODs and an icListenHF hydrophone, for the deepest sites at the FORCE Lease Area.

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.

Test Snow Crab Response to Seismic Stress

February 2012 – September 2013

There is concern in Atlantic Canada that there is insufficient information on the potential effects of seismic noise on snow crab.

Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power

August 2013

Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy.

Community Engagement Strategies & Resource Guide To Support Small-Scale Tidal Power in Nova Scotia

March – July 2013

Community engagement strategies and a resource guide for stakeholders involved in marine renewable energy will support the success of marine renewable energy development in Nova Scotia.

Tidal Energy Resource Assessment Map for Nova Scotia

March – October 2012

This project used numerical simulations and theoretical calculations to predict not only the power that can be extracted from the flow through a passage but also the reduction in flow through the passage.

Mi’kmaq Ecological Knowledge Study (Phase 2)

May 2012

A second Mi’kmaq Ecological Knowledge Study was carried out prior to potential marine renewable energy development in the Brier and Long islands area of the Bay of Fundy, including Grand Passage and Petite Passage.

Assessing the Far Field Effects of Tidal Power Extraction on the Bay of Fundy, Gulf of Maine and Scotian Shelf

January 2010 – April 2012

The Bay of Fundy and Gulf of Maine system has a natural resonant period very close to the main semi-diurnal lunar tide. This results in the world’s highest tides and strong tidal currents in the Bay of Fundy, particularly in the Minas Channel and Minas Basin.
