Drones and Drifters – The Great Pumpkin Race
October 2016 – July 2017
This project tested and developed a new low-cost approach to collecting oceanographic measurements for use in tidal initial site assessments. The plan combines one of the oldest tools in oceanography, the drifter, with one of the newest, the drone.

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.

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.

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.

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.

Seasonal Erodibility of Sediment in the Upper Bay of Fundy
February 2012 – January 2015
This project developed methods for studying sedimentation to the macro-tidal flats of the upper Bay of Fundy. The researchers looked at seasonal variation in the erodibility of sediments in tidal creeks and flats using a Gust Erosion Chamber and repeated grain size surveys.

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.
