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.
Development of High Performance Tidal Turbine Rotors
January 2013 – October 2015
This research investigated and informed novel and cost-effective engineering solutions to extract and deliver energy from tidal flows.
Turbulent Scale and Wake Modeling on a Horizontal Axis Turbine
January – April 2015
This project aimed to accurately simulate turbulent flow over a scaled horizontal axis tidal turbine to resolve turbulence in the near and far field regions.
Turbulence and Bottom Stress in Minas Passage and Grand Passage
September 2011 – February 2015
This project aimed to investigate turbulence and bottom stress at two sites being targeted for in-stream tidal power development in Nova Scotia: Minas Passage in the Upper Bay of Fundy and Grand Passage, located between Brier and Long Island in the lower Bay of Fundy.
Assessing Marine Mammal Presence in and near the FORCE Crown Lease Area during Winter and Early Spring
October 2013 – February 2015
This study closes the winter/spring baseline data gap via deployments of multiple, calibrated C-PODs and an icListenHF hydrophone, for the deepest sites at the FORCE Lease Area.
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.
Observations of Marine Mammals in Petit Passage and Grand Passage, Nova Scotia and Adjacent Waters in the Eastern Bay of Fundy to Assess Species Composition, Distribution, Number and Seasonality.
June – December 2014
This research project implemented a common mobile tool, database, and alert system for recording and acting on marine life sightings, while engaging coastal communities in protection of the marine environment and using crowd-sourcing to collect data for scientific research.
Atlantic Sturgeon Spatial and Temporal Distribution in Minas Passage, Nova Scotia, Canada, a Region of Future Tidal Energy Extraction
January 2010 – January 2014
In the Bay of Fundy, Atlantic sturgeon from endangered and threatened populations in the USA and Canada migrate through Minas Passage to enter and leave Minas Basin.
Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power
August 2013
Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy.
