Performance validation of a remotely operated vehicle (ROV) in a controlled environment
June 2018 – October 2019
In the past few years, the Nova Scotia tidal community has augmented its marine operational capacity, but some unknowns and risks still exist and the cost associated with such operations are high.
Developing Enhanced Marine Operations (DEMO) in High Flow Tidal Environments
October 2017 – October 2019
Conventional subsea remotely operated vehicles (ROVs) perform poorly in currents exceeding 1.5 m/s. This is a key operating limitation in the success and cost of marine operations in the Bay of Fundy, where current speeds reach 5 m/s.
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.
Testing of a New Turbine Blade Design and Blade Materials
July 2018 – May 2019
There’s not yet a standardized, optimal way of extracting power from tidal currents. That’s why many tidal industry technologies are currently being tested around the world.
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
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.
Testing of Temporal Monitoring Techniques for Benthic Habitat Impacts of Tidal Energy Developments
September 2011 – November 2014
This project tested and developed monitoring procedures for assessing the impact of the placement of in-stream tidal devices (e.g. turbines, cables and other seafloor hardware) on the seafloor environment.
Implications of Tidal Energy Extraction on Sedimentary Processes within Shallow Intertidal Environments
September 2011 – April 2014
This project assessed the implications of tidal energy extraction on sedimentary processes within shallow inter-tidal ecosystems.
