SCIENCE AND ENVIRONMENT SPEAKER SERIES
The Science and Environment Lecture Series runs from 7:30 to 9:00 p.m. on the first Tuesday of each month from October to June using the Zoom Webinar format. The on-line format allows large numbers of CALL members to participate and access to a wide range of speakers. A Q& A feature in the Webinar platform provides an opportunity for participants to post questions for the speaker. These are addressed in a curated Q & A session at the end of each presentation. Feedback on each session as well as suggestions for improvement, future topics and so on can be left for the team organizing the lecture series using the Chat feature.

Exploring Martian Geology to Understand How Planets Sustain Life
BY Dr. Benjamin Tutolo
Our neighboring planet, Mars, offers a stark contrast to Earth. While Earth has remained habitable and indeed inhabited for nearly all of its 4.5 billion year history, Mars apparently transitioned to a desert planet early in its history. In this presentation, Dr. Tutolo will discuss how our recent, surprising discovery of sedimentary carbonate minerals in Gale Crater, Mars has revised our understanding of the fate of Martian habitability, and what this means for the planet’s potential for having originated life.
Speaker Bio: Dr. Benjamin Tutolo is an Associate Professor in the Department of Earth, Energy, and Environment at the University of Calgary and a Canadian leader in the field of geochemistry. His pioneering investigations of water-rock interactions on Earth and Mars have provided fundamental insight into the relationships between geologic processes, planetary habitability, and life. His innovative approach to research has also yielded breakthroughs in our understanding of nature-based climate change solutions. He has been a Participating Scientist on NASA’s Curiosity Rover mission to Mars since 2021. |
