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.
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.
Use of Fish Tracking Data to Model Striped Bass Turbine Encounter Probability in Minas Passage
September 2016
This project used fish tracking datasets and VEMCO detection-range tests to calculate fish-turbine encounter probabilities for striped bass.
On-line Interactive GIS Map Platform: An Enabling Initiative for the Emerging Tidal Energy Industry
April 2015 – April 2016
A proof-of-concept Geographic Information System (GIS) platform was developed aiming at building a decision-making tool that integrates complex spatial information of importance to the tidal energy industry while also being scalable, flexible and accessible. The platform was built on open source
Characterizing Tidal Flows and Turbine Power Production in Petit Passage using Oceanographic and CFD Models
September 2015 – March 2016
The goal of this project was to identify potential turbine deployment locations in Petit Passage Nova Scotia, using computational fluid dynamics (CFD) and finite volume coastal ocean models (FVCOM).
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.
Investigation of the Vertical Distribution, Movement and Abundance of Fish in the Vicinity of Proposed Tidal Power Energy Conversion Devices
March 2010 – December 2014
This project studied active fish avoidance of a turbine using the Coda Octopus Echoscope II 3-D multi-beam sonar mounted on a bottom platform. The objective was to observe and quantify the distribution and abundance of fish in the water column and their ability to detect and avoid turbines.
