Georges Bank Research & Data
January 2019
Georges Bank is a large submarine bank (250km by 150km – 40,000 km2) located at the edge of the Atlantic continental shelf between Cape Cod and Nova Scotia.
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.
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.
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.
Impacts of Tidal Energy Extraction on Sediment Dynamics in Minas Basin, Bay of Fundy
February 2010 – December 2012
Researchers developed a numerical hydrodynamic and sediment transport model for Minas Basin in the Bay of Fundy, focusing on the sediment dynamics of the tidal inlets and flats.
Effects of Energy Extraction on Sediment Dynamics in Intertidal Ecosystems of the Minas Basin
January 2010 – May 2012
This project assessed how the dynamics of sedimentation change when energy is extracted from a macro-tidal system. The differences in tidal prism and energy between neap and spring tidal cycles were used as a proxy for energy extraction by in-stream tidal power devices.

Feasibility of a Marine Vibroseis System to Minimize Potential Impacts of Seismic Surveying on Commercial Marine Invertebrates
May 2010 – May 2011
Marine vibroseis (a sound generating system that uses a large oscillating mass to emit a range of frequencies) offers an alternative to air-gun seismic sources and may have fewer environmental effects on marine biota.
