Dr. Zeebe’s research group focuses on element cycling in the ocean, atmosphere and biosphere. This includes greenhouse gases such as carbon dioxide and its impact on Earth’s climate in the past present and future, including ocean acidification. They also study past climate, including reconstruction and modeling of past climate episodes such as the Paleocene-Eocene Thermal Maximum (PETM) as well as validation of so-called paleo-proxies. These are climate indicators recovered from deep-sea sediments or polar ice cores which need to be interpreted properly, just like an ancient language. The tools they use to address these questions range from molecular theory and laboratory experiments to global carbon cycle models.
