We invite you to submit an abstract to our session “Proxies, sedimentologic indicators and biotic effects of Oceanic Anoxic Events through the geologic record” for the North American Paleontological Convention (NAPC24; https://sites.lsa.umich.edu/napc2024/) . The meeting will be held from 17-21 June 2024 at the University of Michigan. The abstract submission deadline is 11:59 PM EST, Saturday, 20 January 2024.

Overview: Periods of widespread Oceanographic Anoxic Events (OAEs) have occurred many times in Earth’s geological past and some have coincided with mass extinctions. This session will include case studies of OAE intervals during, e.g., the late Devonian, end-Permian, early Toarcian, mid-Cretaceous, the Paleocene-Eocene Thermal Maximum and the modern ocean, with overviews of the modern and ancient factors that caused widespread OA and key forcing factors such as volcanic outgassing of CO₂ and high nutrient flux to the ocean. Case studies will discuss the duration of the OAE events as well as the effect on regional and global marine biota. The session will end with discussion of model predictions for widespread future eutrophication because of, e.g., high rates of CO₂ and methane input into the atmosphere and global warming.
