ETEC Online: Dr. Linda Kah, University of Tennessee (NASA Mars Project)
September 18 @ 7:30 am - 8:30 am
On Friday, September 18th. Dr. Kah will join us to speak on the search for habitability. How do we determine the habitability of extraterrestrial environments? Although at its face, this is a rather innocuous question, the answer is incredibly complex and filled with scientific uncertainty. In this presentation, we will explore the basic requirements for life and we will take a look at how habitability (and life) are recorded in the geologic environments of the early Earth. We will then extend our understanding of extraterrestrial habitable environments, with a particular focus on Mars.

Dr. Linda C. Kah
Kenneth R. Walker Professor
Carbonate Sedimentology and Geochemistry Department of Earth and Planetary Sciences
University of Tennessee
My students and I focus on integrating sedimentology, stratigraphy, geochemistry, and microbial ecology in understanding the evolution of the Earth’s biosphere. My primary research projects include reconstructing the ocean-atmospheric oxygenation and the redox structure of Mesoproterozoic shallow marine systems, exploring the effects of changing ocean circulation on the Great Ordovician Biodiversification Event (GOBE), characterizing microbe-mineral interactions in the mineralization of Holocene lacustrine microbialites, and investigating the process of early diagenetic silicification in Proterozoic microbial systems. After more than 20 years as an Earth- based field geologist, I have also begun investigating potential habitable environments in extraterrestrial systems as co-investigator on the Mars Science Laboratory Curiosity rover mission, and am continuing my extraterrestrial work as a co-investigator on the Mars 2020 Perseverance rover mission.
