image: An influx of nutrients to the ocean - catalyzed by higher temperatures - stimulates organic matter production and decomposition, consuming oxygen in the process. This is likely a primary driver of oxygen loss in ancient oceans, and is also happening today.. This material relates to a paper that appeared in the Aug. 9, issue of Science Advances, published by AAAS. The paper, by C.M. Ostrander at Arizona State University in Tempe, Ariz, and colleagues was titled, "Constraining the rate of oceanic deoxygenation leading up to a Cretaceous Oceanic Anoxic Event (OAE-2: ~94 Ma)." view more
