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.

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.

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.
