Using Marine Sedimentary Deposits and Geochemistry to Unravel Changes in Past Climates, Ocean Oxygen Levels, and Biologic Diversity

Thursday March 21, 2019
5:00 pm


 Presenter:  Maya Elrick
Professor of Earth and Planetary Sciences  University of New Mexico
 Series:  Sigma Xi Public Talk
 Abstract:  Ancient marine limestones archive the record of past sea level, climate, chemical, and biologic changes. By combining field work and geochemical and biologic analysis of ancient limestones, our research group is identifying the environmental conditions associated with and between several of the largest mass extinction events in Earth history. Our work is suggesting that time intervals of significant reduced oxygen concentrations in world oceans are associated with many of the extinction events as well as time intervals between the big extinctions.
