In Situ Turbulence Replication and Measurement (InSTREAM)

October 2015 – January 2018

The In Situ Turbulence Replication and Measurement (InSTREAM) project was conceived to address some fundamental questions about the turbulence physics in tidal energy sites and laboratory tanks used to simulate these sites.

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).

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.

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.

Establishment of Baseline Biological Data on Snow Crab (Chionoecetes opilio) Offshore Cape Breton for Future Assessment of Potential Impacts of Seismic Noise on Snow Crab

April 2012 – February 2015

The study investigates the impact of sound energy generated by acoustic/seismic arrays on snow crabs.

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.

3-D Acoustic Tracking of Fish, Sediment-Laden Ice and Large Wood Debris in the Minas Passage of the Bay of Fundy

October 2009 – December 2011

Researchers used VEMCO animal tracking technology to complete in-situ testing of the path, depth and velocity of fish and objects passing through the Minas Passage.

Physics of the Interaction between a Crab and a Seismic Test Pulse – Development of a Mathematical Model and Testing of Model via Simulation

June 2009 – September 2011

Experimental attempts to establish whether seismic testing has any impact on crabs and the crab fishery have been hampered by a lack of theoretical work on the subject.
