英文摘要	Using data on oxygen variability taken from 32 representative reef sites, the authors show that hypoxia is already common. Under future scenarios of ocean warming and deoxygenation, the duration, intensity and severity of hypoxia will increase, with nearly one-third of reefs experiencing severe hypoxia. Ocean deoxygenation is predicted to threaten marine ecosystems globally. However, current and future oxygen concentrations and the occurrence of hypoxic events on coral reefs remain underexplored. Here, using autonomous sensor data to explore oxygen variability and hypoxia exposure at 32 representative reef sites, we reveal that hypoxia is already pervasive on many reefs. Eighty-four percent of reefs experienced weak to moderate (<= 153 mu mol O-2 kg(-1) to <= 92 mu mol O-2 kg(-1)) hypoxia and 13% experienced severe (<= 61 mu mol O-2 kg(-1)) hypoxia. Under different climate change scenarios based on four Shared Socioeconomic Pathways (SSPs), we show that projected ocean warming and deoxygenation will increase the duration, intensity and severity of hypoxia, with more than 94% and 31% of reefs experiencing weak to moderate and severe hypoxia, respectively, by 2100 under SSP5-8.5. This projected oxygen loss could have negative consequences for coral reef taxa due to the key role of oxygen in organism functioning and fitness.
