  • Unveiling Ozone

    Unveiling Ozone
    Mar 3 2026
    There is good ozone and bad ozone. We are discussing the bad ozone today, the one we breathe and can be harmful to our health. Daniel Mendoza, a research associate professor at the University of Utah, discusses the chemistry behind ozone formation, primarily from nitrogen oxides and volatile organic compounds intensified by sunlight. Daniel has started a project to measure air quality and heat in rural Utah communities, using both indoor and outdoor sensors. The discussion includes the challenges of ozone measurement, the role of vegetation like sagebrush in VOC emissions, and the potential benefits of using public cooling centers as environmental refuges. The episode underscores the need for more awareness and education about ozone's health impacts, especially for tourists in areas like Moab.

  • A Modern Wonder from Ancient Dunes: The Iconic Navajo Sandstone, Part 2

    A Modern Wonder from Ancient Dunes: The Iconic Navajo Sandstone, Part 2
    Feb 17 2026
    ​​This episode of Science Moab continues the exploration of the Navajo sandstone with Marjorie Chan, Professor Emeritus at the University of Utah. The unique coloration of the sandstone is influenced by iron oxides that have analogies with the iron oxide 'blueberries' found on Mars and have implications for groundwater evidence on the planet. Margie elaborates on the concretions and weathering patterns within the Navajo sandstone and how these differ from the Wingate sandstone. We also discuss the challenges of geological research funding, the importance of fieldwork partnerships, and the significance of preserving natural geological features and educating the public on their value.

  • A Modern Wonder from Ancient Dunes: The Iconic Navajo Sandstone, Part 1

    A Modern Wonder from Ancient Dunes: The Iconic Navajo Sandstone, Part 1
    Feb 3 2026
    The majestic and iconic Navajo Sandstone has become ubiquitous in scenes from the Colorado Plateau. Margie Chan, Professor Emeritus at the University of Utah, has studied the Navajo Sandstone her entire career and we discuss the deposition and unique features of this Jurassic wind-blown sand. This ancient desert extended across much of Utah, Arizona, and Nevada, and combined different geological structures including dunes, lake deposits, and springs. In this first of a 2-part series, we talk about the key role that groundwater plays in the sediment deformation and coloring. The next episode delves into the role of iron in the Navajo sandstone and its connection to Mars.
