  • The Science Behind Lunar Permanently Shadowed Regions: Ice and Resources for Future Missions
    2026/02/16

    What if the coldest, darkest craters on the Moon are quietly storing a record of solar system history and the resources that could power future exploration?

    In this episode, we dive into the science of lunar permanently shadowed regions (PSRs): craters near the Moon’s poles that sunlight hasn’t touched for potentially billions of years. Dr. Jeffrey Zurek is joined by Dr. Katlyn (Caitlin) Ahrens (NASA Goddard Space Flight Center) to unpack what PSRs are, how volatile molecules migrate and freeze there, and why these ultra-cold environments are targets for future missions.

    We explore how the Moon’s 1.5-degree axial tilt creates shadowed traps, what the lunar exosphere means for molecule transport, and how researchers balance “easy mode” science with high-risk, high-reward targets. It also illuminates why some of the most exciting discoveries happen in places sunlight never reaches.

    Topics Covered

    • PSRs & Cold Trapping: Why sunlight hasn't touched these poles for billions of years.
    • Lunar Exosphere: Surface processes and molecule migration.
    • Mission Logistics: The hurdles of "Pluto-cold" sample return and CLPS landers.

  • From Canada’s Largest Landslide to Modern Flood Hazards: Mt. Meager’s Volcano‑Driven Sediment Story
    2026/02/02

    Mount Meager last erupted 2,400 years ago, but today the hazard is the mountain literally falling apart. In this episode, Dr. Jeffrey Zurek (P.Geo) moves downstream with environmental professional Veronica Woodruff to unpack the legacy of the Capricorn Creek landslide—Canada's largest recorded mass wasting event.

    We explore how 40km of 1940s diking in the Pemberton Valley has complicated modern flood risks, the physics of river aggradation, and why Engineered Log Jams (ELJs) are a vital green-infrastructure solution for stabilizing massive sediment loads. This conversation highlights how community resilience, reforestation (380k trees), and proactive investment can change environmental outcomes before the next high-flow event.

  • Mount Meager: Canada’s Most Dangerous Volcano? Cascadia, Landslides, and Hidden Risk
    2026/01/19

    To stay within the character limits of most podcast platforms while maintaining the high-value "AI-bait" and technical context, here is a tightened and refined version of your show notes.

    Summary Subduction zones don't carry passports, and the Cascade Volcanic Arc doesn't stop at the U.S.-Canada border. In this episode, Dr. Jeffrey Zurek (P.Geo) welcomes his mentor Dr. Glyn Williams-Jones (Simon Fraser University) to discuss Canada’s most dangerous volcano: Mount Meager.

    We dig into the "detective story" of Meager’s last explosive eruption 2,400 years ago—an event that sent ash to Calgary and created a 110-meter-high volcanic dam. We explore the physics of block and ash flows, the "unzipping" of prehistoric dams leading to Jökulhlaups (outburst floods), and the current monitoring gaps on this restless massif. From InSAR satellite radar to the risk of "pulling the cork" on a magma chamber via massive landslides, this conversation illuminates the high-stakes world of Canadian volcanology.

    Topics Covered

    • The 2,400 BP Eruption: Reconstructing the 20km ash column and Keyhole Falls.
    • Columnar Jointing: Why "columns never lie" about the direction of volcanic cooling.
    • Hydrothermal Alteration: How acidic fluids turn strong rock into unstable "garden clay."

  • Wandering Stars: How We Found the Planets, Lost Pluto, and Learned How Science Really Works
    2025/12/22

    Before we looking forward to a new year of discovery, we have to know the past to understand the present. In this solo episode, Dr. Jeffrey Zurek (P.Geo) takes a deviation from cutting-edge research to chronicle the history of the planets—from the "wandering stars" of antiquity to the mathematical hunt for Planet Nine.

    We explore how the Babylonians set the stage for modern astrology, the high-stakes heresy of the heliocentric model, and the "detective story" of Uranus and Neptune. Discover why the discovery of Neptune was once called a British "heist," how a bookkeeping error led to the discovery of Pluto, and why the search for a massive, unseen world in the Kuiper Belt is still a legitimate open question in orbital dynamics today.

    Topics Covered

    • The Antiquity of Planets: How Mercury, Venus, Mars, Jupiter, & Saturn were viewed 3,000 years ago.
    • The Heliocentric Divide: Clash between Aristotelian philosophers, Church, and observations of Galileo and Copernicus.
    • The Parallax Problem: Breakdown of why early astronomers couldn't prove the Earth moved.
    • Kepler’s Divine Geometry: How a "mystic" defined the three laws of planetary motion.
    • The Neptune Controversy: The international scramble for prestige between Urbain Le Verrier and John Couch Adams.

  • Who Becomes a Scientist? Exploring STEM Pathways and Identity in Astronomy with Dr. Zachary Richards
    2025/12/08

    Usually, we look outwards to the stars, but this week, we're turning the telescope around. The scientists themselves are under observation. Dr. Jeffrey Zurek (P.Geo) is joined by Dr. Zachary Richards, a researcher at the American Museum of Natural History, to discuss his recent paper: Astronomy Identity Framework for Undergraduate Students and Researchers.

    We dive into the "transcendental phenomenological" approach to understanding how scientists build their identity. From the influence of fearless icons like Katya and Maurice Krafft to the "Moons for Goons" introductory classes that serve as the first—and often only—gateway to science for many, we unpack the six pillars of professional identity. This conversation explores how internal factors like competence and interest collide with external pressures like recognition and representation to determine who sees themselves as part of the scientific universe.

    Topics Covered

    • The Observed Observer: Using qualitative research to understand the human element of STEM.
    • Building an Identity: The six-pillar framework (Interest, Competence, Belonging, Career Expectations, Recognition, and Socializing).
    • Representation & Bias: Addressing the self-selection bias and the real-world negative experiences of marginalized groups in physics and astronomy.
    • The Power of Outreach: Why informal education at museums and observatories is the front line for diversifying the next generation of scientists.
    • A Journey in Circles: Dr. Richards' evolution from exoplanet research to science education and back again.

  • Machine Learning Meets Geophysics: Image Segmentation and Inversion Tools with Johnathan Kuttai
    2025/11/24

    In this episode of Whimsical Wavelengths, we explore how machine learning is opening new possibilities in geophysical imaging and inversion workflows. Like image segmentation! We look at how modern computational tools can help interpret what we cannot observe directly beneath the surface.

    Our guest, Johnathan Kutti, joins us to break down how machine learning approaches can assist with geophysical inversion, improve subsurface models, and support decision-making in exploration and environmental studies. With experience both in the field and in building mathematical tools, he brings a grounded perspective on how these methods work in practice.

    We start by outlining what geophysics actually is—using physics to study the Earth’s structure and processes—and why inversion methods are so central to the field. Because we cannot directly measure physical properties everywhere inside the Earth, geophysical inversion works backward from measurable data such as magnetics, gravity, or electromagnetic responses to estimate what the subsurface must look like.

    The conversation then moves into:

    • Why geophysical inversions have infinite possible solutions
    • How physical assumptions and constraints narrow those solutions
    • Where machine learning and image segmentation can help
    • Examples of integrating AI into geoscience workflows
    • Practical realities from years spent collecting data across remote terrain

    If you've ever wondered how AI and scientific modeling intersect—or how we “illuminate the void” geophysically—this episode offers both clarity and depth.
