#83 - Dr. Elizabeth K. Thomas

Smart Water Solutions

In this episode, Rhea and I are joined by Dr. Elizabeth K. Thomas, Associate Professor of Geology at the University at Buffalo. Dr. Thomas employs advanced scientific methods to uncover ancient climate secrets. She analyzes lipid biomarkers found in sediment cores, which are cylindrical samples drilled from the Earth's surface containing layers of accumulated sediment. These biomarkers act as chemical fingerprints, revealing signs about past environmental conditions, including variations in precipitation patterns. Additionally, she examines isotopic signatures within these sediment cores. Isotopes, different forms of an element, with varying numbers of neutrons, provide insights into past climate conditions. By integrating these techniques, Dr. Thomas paints a detailed picture of how Earth's climate has evolved and influenced water distribution over millennia. Join us as we explore the fascinating intersection of geology, climate science, and water management.
