A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. Led by researchers at UC San Diego’s Scripps Institution of Oceanography and a large team of national and international colleagues, the study captures the current state of hypoxia—or low oxygen levels—at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.
This is the first paper to document oxygen conditions on coral reef ecosystems at this scale. The findings were published March 16, 2023 in the journal Nature Climate Change.
“This study is unique because our lab worked with a number of collaborators to compile this global oxygen dataset especially focused on coral reefs—no one has really done that on a global scale before with this number of datasets,” said lead author Ariel Pezner, a recent graduate of Scripps Oceanography and current postdoc at the Smithsonian Marine Station in Florida. “We were surprised to find that a lot of coral reefs are already experiencing what we would define as hypoxia today under current conditions.”
