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

Ancient Carbon Dioxide Burps Once Devastated Our Oceans, and Could Do So Again

Learn more about a sequence of increases in the carbon dioxide in our ancient atmosphere, which can tell us about our oceans’ future.

Ancient carbon ‘burps’ caused ocean oxygen crashes — and we’re repeating the mistake

Over 300 million years ago, Earth experienced powerful bursts of carbon dioxide from natural sources—like massive volcanic eruptions—that triggered dramatic drops in ocean oxygen levels. These ancient "carbon burps" led to dangerous periods of ocean anoxia, which stalled marine biodiversity and potentially reshaped entire ecosystems. In a groundbreaking study, scientists combined high-tech climate models with deep-ocean sediment analysis to pinp…

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.

Massive Burps Of Carbon Dioxide Led To Oxygen-less Ocean Environments In The Deep Past - Astrobiology

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. Combining geochemical analyses of sediment cores and advanced climate modeling, the study, […] The post Massive Burps Of Carbon Dioxide Led To Oxygen-less Ocean E…
