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.

Earthquakes in Eastern Canada

There are, on average, over 4,000 earthquakes in Canada each year. Many of those earthquakes occur in Western Canada, but Ontario, Quebec and the Atlantic Provinces also see their fair share of seismic events. On this episode, we’ll be speaking with a seismologist who has spent over 30 years studying earthquakes in Eastern Canada.

Icebergs Can Cause Landslides – New Discovery (Byte-Sized Science)

Alex Normandeau is a research scientist studying submarine landslides. While aboard a Canadian Coast Guard ship in 2018, Alex and his team encountered an iceberg floating in the Southwind Fjord near Baffin Island. When they returned the following year, a new underwater landslide had occurred. See how they were able to connect the dots and discover that icebergs can indeed cause submarine landslides.
