GEOL/E 439 – Advanced Applied Geophysics – Geophysical Design Projects for the 21st Century


Students in GEOL/E 439, Advanced Applied Geophysics, were tasked with solving a real-world problem using geophysical methods from the idea, through survey design and execution, processing and interpretation, to presentation and a final journal style paper delivered to the stakeholders. The following provides a brief summary of the projects using a wide range of geophysical tools. We would like to thank Dr. Terri Brannan, Bill Linnen, Paul MacLatchy, Sue Bazely, and Michael Whittaker for their support of the projects.

 

Pseudogravity of Ontario

Fadhli Atarita, McKenzie Douglas, Pedro Lapietra

For magnetic anomaly interpretations, pseudogravity data can be used as a complementary resource, but there is no available pseudogravity data of Ontario. Using Ontario Geological Survey magnetic data, it was transformed using a pseudogravity transformation. This data was then compared to the available gravity survey data from the Ontario Geological Survey and similar anomalous areas were identified for enhanced geological interpretation.

Battery Park retaining wall: Resistivity, IP, SP

Regan Mahoney, Emily Miszk, Benjamin Saadia

A geophysical investigation was completed to assess the quality of the sheet pile along the shoreline of Battery Park in Kingston, Ontario. Resistivity surveys and volumetric water meter tests were used to determine changes in wall material and corresponding areas of saturation in the overburden. It was concluded that there are either voids, defects, or other material differences in the sheet pile wall that may be related to fluid flow in the nearby overburden.

Burials in Kingston and Merrickville: GPR and volumetric water meter

Lauren Norenberg, Caroline Ochocinski, Tim van Heuvelen

This project was intended to confirm the location of known burial sites and locate previously undiscovered burials at St. Paul’s Anglican Church and Willoughby Cemetery. The team primarily used ground penetrating radar to investigate anomalies in the subsurface, along with a volumetric water meter to confirm these locations. The GPR profiles showed anomalies from both sites that appeared to correlate with surficially marked burials; other anomalies without surface markings can be attributed to other possible burials.

Wolfe Island Wind Turbines: Infrasound and passive seismics

Stephanie Bringeland, Madeline Calvert, Mark McDonald

Undetectable to the human ear, the decay of infrasound and seismic waves produced by the wind turbines on Wolfe Island was measured in the air with an infrasound sensor, and passive seismic methods, in the ground.  These signals were measured at varying distances from the wind turbine and showed infrasound attenuation with increasing distance from the turbine.
