Bogdan P Onac

Bogdan P. Onac’s research interests center on understanding hypogene cave systems and reconstructing climate and paleoenvironmental changes using speleothems, ice, and guano from various cave and karst deposits.  He employs mineralogy, stable and radiogenic isotope geochemistry, and sedimentary records to answer his research questions.  Onac’s publishing record includes over 150 articles and 10 books.  He edited the newly published Cave and Karst Systems of Romania.  A particular aspect of his current and future studies is to contribute data on past sea level positions for both warmer and colder periods of Earth’s history using carbonate encrustations from littoral caves.  He is currently Professor of Karst Geology and Paleoclimate in the School of Geosciences at the University of South Florida.
