Geologists from Natural Resources Canada head to northern Labrador to map the surficial geology impacted by the last ice age. Join Roger Paulen, Pierre-Marc Godbout and Jessey Rice as they use their detective skills to map the former paths of these once great ice sheets.

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.

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.
