Lions Field House – 270 Elkhorn Road (Highway 67), Williams Bay, WI
Free to attend and open to the public!
Speaker: Annie Bauer
Topic: The Rise of Oxygen in Earth’s Atmosphere 2.5 Billion Years Ago
Annie will describe what we know about the trajectory of atmospheric oxygen concentrations over billion-year timescales on the Earth, and how this is critical for our understanding of the evolution of complex life.
About the speaker: Annie Bauer is a geologist and geochronologist– she studies how the Earth became a habitable planet, from the origin and evolution of the earliest continents to the development of an oxygen-rich atmosphere. In her work, Annie uses the decay of radioactive isotopes in rocks and minerals as chronometers and tracers of major geological processes.
