Maya Elrick is Professor of Earth and Planetary Sciences at the University of New Mexico. Her research focuses on the use of sedimentary geology to address ancient oceans, past climates and interactions of between past climate changes, oceanographic changes, and biologic changes.
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.
