Exploring the minerals in old clay and rock samples using modern techniques (Byte-Sized Science)

Research scientist Jessey Rice was unable to do field work during the global pandemic, so he took this opportunity to utilize the Geological Survey of Canada’s world class collection and reanalyze archived glacial sediments and rock samples using modern techniques. Focusing on samples from the Keewatin sector in Nunavut, the project aims to investigate the smallest minerals that make up these samples for insights into glacial landscape evolution and mineral dispersal.


Where do you find old iconic rock stars? In Canada, of course!

Did you know that Canada is home to the oldest rock ever discovered? It’s the 4.03-billion-year-old Acasta gneiss. For most of us, four billion years is an unimaginable length of time. So how do we know this rock is in fact almost as old as Earth itself? Simply Science visits a highly specialized Geological Survey of Canada lab in Ottawa to meet a team of time-travelling rock star experts who figure this all out.


Using seismic surveys to study groundwater (Byte-Sized Science)

Kevin Brewer is a geophysical technologist responsible for building, designing and maintaining various pieces of equipment used in survey work. One of his designs, the microvibe, generates a frequency sweep that travels down into the ground and reflects back up. This microvibe allows the creation of detailed images of the ground very similar to an ultrasound.
