Protoplanetary Disks and Backward Spinning Stars with J. J. Zanazzi

September 28, 2021 15:30 - 41 minutes - 94.4 MB

We typically expect physical phenomena to follow certain rules: an apple falls from a tree under the influence of gravity, a skater will eventually slow down from the friction between their skates and the ice, a star spins in a similar direction as the planets in its solar system... Here's the interesting bit, the last one doesn't always hold true. In fact, astrophysicists theorized that there are solar systems in outer space that don't follow this rule. And in 2019, scientists measured this...

Canada's Nuclear Waste Management Plan with Andrew Parmenter

August 29, 2021 21:00 - 41 minutes - 95.5 MB

In this episode, we interview Andrew Parmenter, a geologist working for the Nuclear Waste Management Organization (NWMO), a not-for-profit organization tasked with the safe, long-term storage of Canada’s used nuclear fuel in a manner that protects people and the environment for generations to come. Nuclear waste is a reality our generation has been tasked with storing in a safe way after being passed on from previous generations. We touch upon the key features of long-term nuclear waste repo...

The History of Earth Sciences Education with Erik Klemetti

March 14, 2021 21:00 - 43 minutes - 100 MB

Many Earth Sciences Departments have been recording low enrollment numbers for the last decade. This field has been known to ride the industry wave; high enrollment when the oil, petroleum, and mineral resource industry is booming, low when it's not. This time, the ebb and flow of markets aren't the cause. General public mistrust of the industry, lack of diversity, and reliance on courses that no longer seem to fit with modern problems are just a few reasons Assistant Professor Erik Klemetti...

Compositions of Exoplanets and their Stars with Diana Valencia

February 28, 2021 22:00 - 48 minutes - 110 MB

The first exoplanet was discovered in 1992 by Aleksander Wolszczan and Dale Frail. Less than 30 years after this initial discovery that won the Nobel Prize in Physics, more than 4000 exoplanets have been confirmed (NASA). These planets, while unique, have some similarities in mass and size, and potentially other features, to Earth. While we aren't able to take a sample from the surface of these planets, that doesn't mean we're limited to simply guessing at their composition. Associate Profes...

Flood Risks and Hazards with Joseph Desloges

February 14, 2021 22:00 - 45 minutes - 104 MB

With natural disasters become more frequent and damaging, how can we accurately access who's at risk without updated information and predictions? The answer is we can't. That's why accurate risk and hazard mapping is essential for both private homeowners and all levels of government that have a public responsibility to mitigate the adverse after-effects of disasters. In this episode we talk to Professor Joseph Desloges of the Geography and Planning Department at the University of Toronto. He...

The Life and Legend of the Ediacaran Biota with Marc Laflamme

January 31, 2021 22:00 - 57 minutes - 132 MB

Imagine if you lived in a world where some humans evolved the ability to fly, use one hundred percent of their brainpower, or the ability to reproduce at twice the normal rate. These evolved humans would certainly have an evolutionary advantage over the rest of us, and likely outcompete us in the long-term. What if a similar situation happened around 541 million years ago? Around this time, in the late Neoproterozoic, the Ediacaran biota, mostly filter-feeding and immobile organisms, faced t...

Special New Years Episode

Ultrafast Metamorphic Reactions with Xu Chu

November 16, 2020 12:01 - 44 minutes - 55.7 MB

We're used to thinking of geologic phenomena as events that take millions of years. Think mountain building, subduction, or even the rock and carbon cycles. In this episode, we talk with Assistant Professor Xu Chu about a new discovery in metamorphic petrology: ultra-fast fluid-rock interactions and what they mean for earth system processes through geologic time.    Primary Readings Discussed:  Instantaneous rock transformations in the deep crust driven by reactive fluid flow

Fracking Induced Seismicity with Dr. Semechah Lui

September 27, 2020 17:30 - 44 minutes - 52.3 MB

It's often inconceivable that we can have such a big impact on the environment around us, but nonetheless, humanity has molded the planet to meet its needs. This molding came with its own unintended consequences: Fracking induced seismicity is the crust responding to oil and natural gas exploitation by releasing energy. Even though most of these energy releases are small, some of them are registered as fairly large earthquakes that have the potential to cause infrastructure damage. We talk t...

The Ocean and Carbon Sequestration with Elizabeth Phillips

September 07, 2020 02:57 - 47 minutes - 57.1 MB

Removing excess carbon in the atmosphere generated from human industrial activity is one of the most relevant geoengineering feats of this century. But what if we told you the oceans and coastal areas have been doing this naturally for billions of years? In this episode, we sat down with PhD candidate Elizabeth Phillips to talk about speeding up the rate of carbon removal in the ocean. We discuss possible dangers to ecosystems, global challenges and social responsibility.  Primary reading d...

Monitoring Volcanic Eruptions with Paul Ashwell

August 23, 2020 21:00 - 1 hour - 51.9 MB

Volcanoes have captured the imagination and intrigue of the human civilization because of their unpredictable and destructive nature. Today, hundreds of volcanoes are being monitored for potential warning signs that precede an eruption including gas emissions, seismic tremors and ground deformation. We sit down with volcanologist Paul Ashwell to ask how the monitoring of  volcanoes has improved over the last half century and what challenges still lie ahead.    Primary reading discussed:  ...

The Nuclear Waste Storage Problem with Don Davis

August 16, 2020 21:00 - 50 minutes - 39.9 MB

In this episode, we discuss both the engineering and socio-political problem that nuclear waste storage has posed since the 1940's. Dealing with tonnes of radioactive waste that needs to be safely stored for hundreds of thousands of years is no easy feat, and as such it has been passed off to every new generation of scientists and engineers. Dr. Donald Davis has worked with radioactive elements in more ways than one in the Jack Satterly Geochronology Laboratory at the University of Toronto. ...
