How Does Sound Travel in High Energy Environments? Effectiveness of Acoustic Monitoring Systems and Turbine Audibility Assessment

April 2017 – December 2020

The researchers are designing and implementing a long-term acoustic monitoring program to support tidal energy development in the Bay of Fundy. Specialized acoustic instrumentation was deployed for a two-month period in Grand Passage to advance understanding how turbulence affects the ability to

Reducing Costs of Tidal Energy through a Comprehensive Characterization of Turbulence in Minas Passage

October 2017 – March 2020

Turbulence is a significant issue at every site being considered for in-stream tidal energy development.

Greater North Atlantic Liassic Petroleum Systems Synthesis

October 2019 – February 2020

In the absence of definitive, direct evidence for a Liassic (i.e. Lower Jurassic) petroleum system offshore Nova Scotia, information is required on source rock analogs around the greater North Atlantic region.

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.

Shelburne Sub-Basin Play Fairway Analysis Update

November 2018 – June 2019

Shortly after the Scotian Shelf and Slope Play Fairway Analysis (PFA) was released in 2011, Shell Canada acquired six exploration parcels in the Shelburne Subbasin and collected approximately 10,850 square kilometers of wide azimuth 3D seismic data.

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

Going with the Flow II: Using Drifters to Address Uncertainties in the Spatial Variation of Tidal Flows

October 2017 – June 2018

Drifters are one of the oldest, simplest and most reliable methods for measuring ocean currents. Drifters also provide a simple, low risk platform from which to gather acoustic information along flow streamlines or ‘drift tracks’.

Numerical Modeling of Tidal Turbine Behaviour under Real Turbulent Tidal Flow Conditions

December 2015 – December 2016

Researchers investigated and numerically quantified the behaviour of a tidal turbine under turbulent unsteady tidal flow, using flow data collected in the lower Bay of Fundy (Digby area).

Turbulence in Grand Passage Nova Scotia: Measures of Intermittency

April – December 2016

Turbulence research is very important to advancing the in-stream tidal energy sector, however turbulence in general is not well understood.  Measurement at prospective turbine locations is essential prior to development, given the high degree of spatial variability between sites.
