Geoscience seminar Feb. 6: Climate variability in the late Early Cretaceous

The Department of Geosciences presents “Timing and quantification of terrestrial climate variability in the late Early Cretaceous” with Marina Suarez from the University of Kansas at 3 p.m. on Monday, Feb. 6, 2023, in the Ruch Engineering Building, Room 103. A cookie and coffee social hour before the seminar will be held at 2 p.m. in the Environmental Research Building main lobby.

“While the Cretaceous is known to be a time of global warmth, detailed paleoceanographic data suggest that the Cretaceous did experience climate variability,” Suarez’s abstract for the seminar says. “The continental record offers the ability to examine pCO2 proxies, temperature, and precipitation for a more complete picture of the Cretaceous climate. This project utilizes carbon isotope chemostratigraphy, geochronology, and geochemical proxies from multiple localities (Utah, China, and Texas) to determine if C-cycle changes indicated in marine strata have also resulted in climate changes in terrestrial records.”
