Multi-Scale Turbulence Measurement in the Aquatron Laboratory

July 2018 – July 2019

This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.

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).

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.

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.

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.

Feasibility of a Marine Vibroseis System to Minimize Potential Impacts of Seismic Surveying on Commercial Marine Invertebrates

May 2010 – May 2011

Marine vibroseis (a sound generating system that uses a large oscillating mass to emit a range of frequencies) offers an alternative to air-gun seismic sources and may have fewer environmental effects on marine biota.

Near Field Effects of Tidal Power Extraction on Extreme Events and Coastline Integrity in the Bay of Fundy

January 2010 – March 2011

Researchers quantified the near-field effects of power extraction on the resulting effects of extreme storm events and coastline integrity by implementing a spectral wave model to numerically simulate wave transformation for tidal current conditions with and without turbines.

Nova Scotia Tidal In-Stream Energy Conversion (TISEC): Survey and Characterization of Potential Project Sites

October 2006

This study produced system designs for in-stream tidal energy devices, performance estimates, cost estimates and economic assessments for one site/device per state/province.
