Measuring the Acoustic Detection Range of Large Whales from an Ocean Glider to Improve an Acoustic Whale Alert System for use by the Offshore Marine Industry in Atlantic Canada
April 2017 – January 2018
Researchers investigated a novel and in-development passive acoustic monitoring (PAM) system for use as a marine mammal detection technique. The work builds on a current research initiative between Dalhousie University and Woods Hole Oceanographic Institute (WHOI).
Finite Element Analysis to Assess Fish Mortality from Interactions with Tidal Turbine Blades
February – December 2017
The research project used finite element analysis (FEA) to simulate the impact of a tidal turbine blade on fish, and assess whether mortality of marine life can be expected in such an event.
Turbulence Dissipation Rates from Horizontal Velocity Profiles at Mid-Depth in Fast Tidal Flows
December 2017
This study characterizes the turbulence in a tidal channel in the Bay of Fundy that has been identified for development as a tidal power resource.
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.
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.
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.
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.
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.
