Science and Socio-economic Review of the Georges Bank Prohibition Area 2020-2021

June – December 2021

Georges Bank is a large submarine platform located at the edge of the Atlantic continental shelf between Cape Cod and Nova Scotia. The Georges Bank Prohibition Area covers a significant portion of Georges Bank and is located on the Canadian side of the Canada-United States maritime boundary.

Review of Nova Scotia Power Transmission System Interconnection Requirements

April – May 2021

Power Advisory was engaged by OERA on behalf of the Nova Scotia Department of Energy & Mines to review the recently released Nova Scotia Power Transmission System Interconnection Requirements (TSIR) and identify any gaps between recommendations made by Power Advisory in their August 2020 repo

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.

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.

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. 

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.

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.

Passive Acoustic Monitoring of Cetacean Activity Patterns and Movements Pre- and Post-deployment of TISEC devices in Minas Passage

June 2011 – July 2013

This project aimed to conduct pre- and post- in-stream tidal energy device deployment assessments of marine mammal activity and to assess the potential risk for interaction with turbine infrastructure.
