Earth's climate has not been constant throughout history. Oxygen levels in the atmosphere, for example, have increased by many orders of magnitude over time, profoundly affecting biologic and chemical cycles at the surface of the earth. These changes in Earth's climate can be traced through the imprints left behind inside the planet. In this lecture, Claire E. Bucholz (Assistant Professor of Geology; Biedebach Memorial Lecturer, Division of Geological and Planetary Sciences) will explore how such shifts in atmospheric oxygen concentrations altered Earth's inner workings. This lecture will be presented in a hybrid format, allowing for both virtual viewers and in-person attendees. No advance registration is required for either format but you may sign up for event reminders here. How to watch online - The lecture can be viewed via live stream on caltech.edu/watson or on Caltech's YouTube channel. Virtual viewers can submit questions for the lecturer through the YouTube chat feed. Select questions will be answered after the lecture, during the audience Q&A. How to attend in person - Local participants can attend the lecture inside Caltech's Beckman Auditorium. Doors open at 7:00p.m. For more information, visit the above link.
