Available Expert - A delicate task: detecting unmarked graves on the grounds of former residential schools

Friday, June 25, 2021

Given the devastating news about another discovery of unmarked graves on the grounds of a former residential school in Saskatchewan, Queen’s University expert Alexander Braun (Geophysics) is available to explain the technology and technique being used to carefully look underground to detect anomalies. 

“We use three geophysical methods, Ground Penetrating Radar, soil moisture meter, and passive seismics,” says Dr. Braun. “This will give us different information about the subsurface. All of the methods are non-invasive, meaning that there is no digging, drilling or explosives involved. All methods are intrinsically imperfect, which means that the results are never 100 per cent correct nor complete, the interpretation is the most delicate part of such a survey.”

Dr. Braun can speak to the technique itself, how it works, and how it might advance these delicate searches.

He and his team will also start the initiative of offering pro bono surveys, training and reviews to any indigenous community in Canada.
