Spectral and Structure Function Estimates of Turbulence Dissipation Rates in a High Flow Tidal Channel Using Broadband ADCPs

January 2016

Spectral and structure function methods are implemented to compute the dissipation rate, ε, from broadband, diverging-beam, acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal channel.

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.

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.

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.

3-D Acoustic Tracking of Fish, Sediment-Laden Ice and Large Wood Debris in the Minas Passage of the Bay of Fundy

October 2009 – December 2011

Researchers used VEMCO animal tracking technology to complete in-situ testing of the path, depth and velocity of fish and objects passing through the Minas Passage.

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.

Assessment of the Potential of Tidal Power from Minas Passage and Minas Basin

October 2009 – September 2011

This project estimated the power potential of the tides and tidal currents in the Minas Basin and Minas Channel regions of the Bay of Fundy.
