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.

The Smoking Hills

In Cape Bathurst, where Canada's mainland meets the Arctic Ocean, an entire coastline is burning. Aptly named the Smoking Hills, it's home to a really unique geological feature: a deposit of sedimentary rock that's been burning and smouldering continuously for thousands of years. On this episode, we'll be speaking with a research scientist who visited the hellish landscape to study it first-hand.
