Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions
April 2018 – April 2019
Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).

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.
Turbine Wake Characterization
November 2017 – March 2019
Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays. In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings. It is thus desired to not just delineate wake

Georges Bank Research & Data
January 2019
Georges Bank is a large submarine bank (250km by 150km – 40,000 km2) located at the edge of the Atlantic continental shelf between Cape Cod and Nova Scotia.
Marine Renewable Energy: Background Report To Support a Strategic Environmental Assessment (SEA) for the Cape Breton Coastal Region, inclusive of the Bras D’Or Lakes
June – December 2012
In 2011 following a competitive request for proposal process, OERA commissioned AECOM’s Halifax office to undertake a Strategic Environmental Assessment (SEA) for marine renewable energy in Cape Breton.
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.
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
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.
Assessment of Hydrodynamic Impacts throughout the Bay of Fundy and Gulf of Maine due to Tidal Energy Extraction by Tidal Lagoons
January 2010 – December 2011
The researchers extended existing hydrodynamic models of tidal flows in the Bay of Fundy to simulate the presence and operation of a tidal lagoon project located in the Minas Basin.

Physics of the Interaction between a Crab and a Seismic Test Pulse – Development of a Mathematical Model and Testing of Model via Simulation
June 2009 – September 2011
Experimental attempts to establish whether seismic testing has any impact on crabs and the crab fishery have been hampered by a lack of theoretical work on the subject.
