Massive burps of carbon dioxide triggered widespread ocean anoxia 300 million years ago, sediment cores suggest

New research from the University of California, Davis, the Chinese Academy of Sciences and Texas A&M University reveals that massive emissions, or burps, of carbon dioxide from natural Earth systems led to significant decreases in ocean oxygen concentrations some 300 million years ago.
