Application of (Low-Cost) Drifters with Suspended Hydrophone Arrays to Assess Harbour Porpoise Use of the Water Column and Spatial Overlap with MRE Devices in the Minas Passage
October 2017 – April 2019
The project investigated the use of a new low-cost drifter technology to monitor the activity and depth distribution of harbour porpoises frequenting the Minas Passage and Minas Channel.
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).
Quantifying Demographics and Monitoring Movement of American Lobster in the Minas Passage and Basin
October 2017 – March 2019
The project consists of lobster fishing in Minas Passage during the fall lobster season to collect, assess and tag lobsters in this area, then fishing in Minas Basin from April to May to assess the spawning characteristics of lobster tagged the previous fall, then returning to Minas Passage to fi
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.
Acceleration/Particle Velocity (PA/PV) Measurement System Evaluation in a Tidal Environment
February 2017 – December 2018
The objective of this project was designing and running a field experiment to test the performance of the Particle Acceleration/Particle Velocity (PA/PV) vector sensor.
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.
Analysis of Tidal Turbine Mooring Systems in Turbulent Flows Applying the (Wind Industry) FAST Simulation Tool and DSA ProteusDS Software
March – September 2018
For floating tidal turbine platforms, the turbine forces and resulting platform motions have a direct impact on the lifetime of its moorings and cables. This means the tidal sector must predict accurate tidal turbine loading on floating platforms to determine mooring life and cable longevity.
Assessing Corrosion, Wear, Fatigue and VIV on Moorings and Cabling to Reduce Risk in Marine Operations
October 2017 – August 2018
The cost of cabling and moorings over the entire life of a tidal energy project is a significant proportion of total project expenditures and the potential failure of these components remains a major risk for the emerging tidal energy sector.
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’.
