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

Real-Time, Targeted Imaging of Turbine-Marine Life Interactions

March 2017 – February 2019

The research goal is to redesign and validate a dynamic mount to improve targeted real-time imaging of marine life in the near-field zone of a tidal turbine. The adjustable mount will enable imaging sensors to be aimed directly facing the tidal turbine.

Using Radar to Evaluate Seabird Abundance and Habitat Use at the Fundy Ocean Research Center for Energy Site near Parrsboro, Nova Scotia

April – September 2018

Shore-based seabird surveys conducted at the Fundy Ocean Research Center for Energy (FORCE) in Parrsboro, NS, determine abundance, habitat use and potential risk to seabirds at the site.

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’.

Measuring the Acoustic Detection Range of Large Whales from an Ocean Glider to Improve an Acoustic Whale Alert System for use by the Offshore Marine Industry in Atlantic Canada

April 2017 – January 2018

Researchers investigated a novel and in-development passive acoustic monitoring (PAM) system for use as a marine mammal detection technique. The work builds on a current research initiative between Dalhousie University and Woods Hole Oceanographic Institute (WHOI).

Finite Element Analysis to Assess Fish Mortality from Interactions with Tidal Turbine Blades

February – December 2017

The research project used finite element analysis (FEA) to simulate the impact of a tidal turbine blade on fish, and assess whether mortality of marine life can be expected in such an event.

Turbulence Dissipation Rates from Horizontal Velocity Profiles at Mid-Depth in Fast Tidal Flows

December 2017

This study characterizes the turbulence in a tidal channel in the Bay of Fundy that has been identified for development as a tidal power resource.

High-Resolution Numerical Model Resource Assessment of Minas Passage, Bay of Fundy

January 2017

Two numerical models developed by the Acadia Tidal Energy Institute are described. The models simulate the tidal flow in the Bay of Fundy, and in particular the Minas Passage. The models have different grid resolution, one suitable for site assessment and one suitable for resource assessment.
