Gallagher Colloquium Series

The Gallagher Colloquium Series is a public lecture series hosted by the Department of Geoscience in the Faculty of Science. Taking place between September and April each year, the Colloquium brings in best-in-class speakers to Calgary to strengthen our science community and to increase scientific knowledge and awareness in the public.

Philanthropic Supporters behind the Series:

The Gallagher Colloquium Series was established in 2015, with a generous philanthropic contribution from the Gallagher family. Legendary oilman and geologist Jack Gallagher was a dedicated supporter of UCalgary, and his sons Thomas, Frederick and James have continued this tradition of generosity. The Gallagher family has also established the Gallagher Library, the Gallagher Fellowship in Geoscience, and many other university initiatives for more than 40 years. We thank the family for their continued support and contributions to UCalgary.

Cells in water

Salty waters: Life’s origins and biological habitability on Earth (and Mars?)

How did life begin? It is a question so fundamental that it has been pondered since at least the time of the ancient philosophers Epicurus and Lucretius. As scientists have sought answers to this question and its logical derivative – Are we alone in the universe? – a common strategy, “follow the water,” has emerged. In this presentation, I will introduce recent scientific advances in the quest to understand the chemical origins of life and discuss our efforts to place these reactions into their appropriate geological context. I will focus on the role of solute-laden, “salty” waters in generating habitable conditions and their potential for originating the first organisms. My discussion will be informed by our geochemical and geophysical studies of saline lakes in British Columbia, intensive study of seafloor hydrothermal systems, and decades of discovery by Mars rovers and orbiters. I will conclude by discussing ways in which these salty waters may be vital in our quest to stem off the worst consequences of global climate change and maintain habitable conditions on our own planet.

Driving Curiosity: Exploring Martian Geology and Habitability through Mineralogy

Mars has long been a source of curiosity and intrigue for humankind – we look out to our nearest cousin to better understand our own formation and evolution, the broader characteristics of our solar system and beyond, and whether or not we are alone in the universe. This desire to explore has led to many orbital and landed missions to Mars, with many striking and surprising discoveries made. One such mission is the NASA Mars Science Laboratory (MSL), with the Curiosity rover housing the most advanced and extensive payload of scientific instrumentation ever sent to another planetary object.

Geological Storage of Carbon and the Role of Geophysics

Global efforts to reduce anthropogenic carbon emissions to the atmosphere are gaining momentum. Geological storage of CO2 is recognized as an important component of most reduction strategies and can contribute to the sequestration of excess CO2 already in the atmosphere. However, to be effective, the quantity of CO2 to be stored must be larger – by several orders of magnitude – than current underground injection of waste fluids or gas storage. This will require new monitoring and storage protocols and geophysical methods will play an important role in all stages of CO2 storage projects including site selection, geological characterization, and long-term monitoring. In this lecture, Dr. White will examine the Aquistore CO2 Storage Project in Saskatchewan, an on-going CO2 measurement, monitoring and verification project to demonstrate the feasibility of deep saline geological formation storage.

How Life and Rocks Co-Evolve: The 4.5-Billion-Year Story of Earth

The story of Earth is a 4.5-billion-year saga of dramatic transformations, driven by physical, chemical, and—based on a fascinating growing body of evidence—biological processes. The co-evolution of life and rocks unfolds in an irreversible sequence of evolutionary stages. Each stage re-sculpted our planet’s surface, while introducing new planetary processes and phenomena. This grand and intertwined tale of Earth’s living and non-living spheres is coming into ever-sharper focus. Earth’s evolution progressed by a sequence of chemical and physical processes, which ultimately led to the origin-of-life. Once life emerged, mineralogy and biology co-evolved, as changes in the chemistry of oceans, the atmosphere, and the crust dramatically increased Earth’s mineral diversity to the more than 5700 species known today.

In 2020 he was elected Foreign Member of the Russian National Academy of Sciences. The biomineral “hazenite” was named in his honor.

Since 2008, Hazen and his colleagues have explored “mineral evolution” and “mineral ecology”—new approaches that exploit large and growing mineral data resources to understand the co-evolution of the geosphere and biosphere. In October 2016, Hazen retired from a 40-year career as a professional trumpeter, during which he performed with numerous ensembles including the Metropolitan Opera, Royal Ballet, and National Symphony.

Enhanced Weathering as an Ore Processing Technique for CO2 Mineralization & Critical Metal Recovery

The critical metals needed to build infrastructure for the renewable energy transition are commonly found in ultramafic rocks. This type of rock is abundant in Canada. It can also be used to bind carbon dioxide (CO2) from the atmosphere within carbonate minerals, which are common components of antacids and the Rocky Mountains. Enhanced weathering of ultramafic rock to make carbonate minerals has potential to store billions of tonnes of CO2 per year while improving the efficiency of critical metal recovery from mines. This talk will describe how using CO2 sequestration as an ore processing technology could turn mining into a carbon negative industry while enhancing the supply of the metals we need to create the green economy.

Co-metabolic Innovation along Eco-thermodynamic Gradients

For over 3.5 billion years microorganisms have evolved to solve complex metabolic problems at the individual, population and community levels, innovating distributed solutions to nutrient and energy conversion processes that have fundamentally transformed the surface chemistry of the earth and generated a deep reservoir of genomic diversity. Over the past decade, high-throughput sequencing and mass spectrometry platforms have transformed our perception of this microcosmos, illuminating microbial dark matter and conceptually linking microbial interactions to a wide range of ecosystem functions and services. Dr. Hallam will explore problems and solutions in environmental sequence analysis spanning different levels of biological organization along defined redox gradients in the ocean. He will highlight emerging open source tools for integrating and visualizing multi-omic (DNA, RNA and protein) and environmental parameter information, and consider the future of data intensive computation and environmental sensing as it relates to metabolic pathway reconstruction, predictive modeling and synthetic ecology.

Mountain Hazards Cascades in North America and High Mountain Asia

Geohazards, including landslides and floods, are becoming more common with climate change. As glaciers melt and permafrost thaws, steep slopes are becoming less stable and more prone to failure, which can result in disaster when the geophysical event intersects with human settlements and infrastructure. In this talk, Dr. Shugar will discuss the changing hazards landscape, with particular attention to recent events in the mountain landscapes of western North America and High Mountain Asia.
