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.

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.

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.

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.

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
