This $293,010 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research at The Ohio State University to develop novel isotope proxies that improve understanding of Earth's climate and carbon cycle dynamics at the onset of the Late Paleozoic Ice Age from 350 to 290 million years ago. The grantee will pair calcium and clumped isotope systems to test hypotheses regarding diagenetic influences on stable carbon isotopes used as proxies for carbon cycling, and to distinguish the roles of temperature versus ice volume in marine oxygen isotope records from this period. The research aims to transform understanding of relationships between global carbon cycling and climate in Earth's deep past. It will also provide training for early career scientists, including those from underrepresented groups, and develop hands-on demonstrations to improve student comprehension of the carbon input-output balance in Earth's atmosphere. Outcomes seek to strengthen the national scientific enterprise through expanded fundamental geoscience knowledge as outlined in the program objectives of the National Science Foundation's Geosciences program.
