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.

Sydney Basin Play Fairway Analysis Atlas (2017)

July 2017

The objectives of this Play Fairway Analysis are to build a detailed and comprehensive understanding of the petroleum systems of the Sydney Basin and provide a resource evaluation based on the petroleum systems assessment.  The study concludes there is an effective petroleum system charged by mai

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.

Acoustic Tracking of Fish Movements in the Minas Passage and FORCE Crown Lease Area: Pre-Turbine Baseline Studies

June 2011 – July 2013

This project used animal tracking technology developed by VEMCO, a division of AMIRIX Systems of Halifax, NS. The technology allows researchers to track animal movements and behaviour over a scale of kilometers.

Community and Business Toolkit for Tidal Energy Development

November 2011 – March 2013

This toolkit covers the science, technology, business and community aspects of tidal energy development in Nova Scotia, effectively integrating the applied, natural and social sciences. It can serve as a model for future applied interdisciplinary work on tidal energy and marine renewables.

Cape Breton Tidal Energy Resource Assessment

November 2011 – October 2012

In support of the Strategic Environmental Assessment (SEA) for the Cape Breton Region, inclusive of the Bras d’Or Lakes, Acoustic Doppler Current Profiler (ADCP) units were deployed at Barra Strait, Seal Island Bridge and Carey Point to collect tidal flow information.  Potential sites for tidal e

Scoping Study on Socio-Economic Impacts of Tidal Energy Development in Nova Scotia: A Research Synthesis & Priorities for Future Action

November 2011 – January 2012

This scoping study highlights many socio-economic issues related to in-stream tidal energy development and discusses best practices, case studies and tools developed to facilitate positive socio-economic benefits and community development.

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.
