Prospectivity of the Shelburne Subbasin, Scotian Margin: An Integrated Multidisciplinary and Multiparameter Approach from Plate to Pore Scale (part of the PAGEO research program)

January 2021 – June 2023

This project will significantly increase our understanding of both the reservoir potential of Tertiary sequences within the Shelburne Subbasin, offshore Nova Scotia, and the crustal architecture underlying this critical region located at a proposed transition from a magma-rich to a magma-poor con

Geologic Origin of Deep Crustal and Uppermost Mantle Structures at the Continent-Ocean Transition Offshore Nova Scotia from Modeling of Wide-Angle S-Wave Arrivals (part of the PAGEO research program)

January 2021 – June 2023

This work will produce S-wave velocity models for two of the existing refraction profiles from the Scotian margin. The objective is to better constrain the crustal origin of the continent-ocean transition (COT) using both the P and S-wave velocity models.

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

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.

Assessing the Far Field Effects of Tidal Power Extraction on the Bay of Fundy, Gulf of Maine and Scotian Shelf

January 2010 – April 2012

The Bay of Fundy and Gulf of Maine system has a natural resonant period very close to the main semi-diurnal lunar tide. This results in the world’s highest tides and strong tidal currents in the Bay of Fundy, particularly in the Minas Channel and Minas Basin.

Assessment of Hydrodynamic Impacts throughout the Bay of Fundy and Gulf of Maine due to Tidal Energy Extraction by Tidal Lagoons

January 2010 – December 2011

The researchers extended existing hydrodynamic models of tidal flows in the Bay of Fundy to simulate the presence and operation of a tidal lagoon project located in the Minas Basin.

Near Field Effects of Tidal Power Extraction on Extreme Events and Coastline Integrity in the Bay of Fundy

January 2010 – March 2011

Researchers quantified the near-field effects of power extraction on the resulting effects of extreme storm events and coastline integrity by implementing a spectral wave model to numerically simulate wave transformation for tidal current conditions with and without turbines.
