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.

SW Nova Scotia Expansion Atlas (2015)

January 2015

This project is an expansion of the 2011 Play Fairway Analysis to the western border of the Nova Scotia marine shelf. This expansion corresponds to the Georges Bank zone and surrounding area extending from the Yarmouth Arch to the Shelburne Sub-basin.

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. 

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.

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.

Impacts of Tidal Energy Extraction on Sediment Dynamics in Minas Basin, Bay of Fundy

February 2010 – December 2012

Researchers developed a numerical hydrodynamic and sediment transport model for Minas Basin in the Bay of Fundy, focusing on the sediment dynamics of the tidal inlets and flats.

Cape Breton Tidal Energy Resource Assessment

November 2011 – October 2012

In support of the Strategic Environmental Assessment (SEA) for the Cape Breton Region, inclusive of the Bras d’Or Lakes, Acoustic Doppler Current Profiler (ADCP) units were deployed at Barra Strait, Seal Island Bridge and Carey Point to collect tidal flow information.  Potential sites for tidal e

Effects of Energy Extraction on Sediment Dynamics in Intertidal Ecosystems of the Minas Basin

January 2010 – May 2012

This project assessed how the dynamics of sedimentation change when energy is extracted from a macro-tidal system. The differences in tidal prism and energy between neap and spring tidal cycles were used as a proxy for energy extraction by in-stream tidal power devices.
