AI Insight
A collaborative research team from HKUST, IOZ-CAS, and GML has demonstrated that coral reef ecosystems in the South China Sea harbor significant carbon storage capacity that has historically been underestimated. The study, published in Advanced Science, shows that reef-dwelling fish, corals, and surface sediments collectively contribute to carbon reservoirs comparable in magnitude to those found in mangroves and seagrass beds. This finding reframes coral reefs as potentially important blue carbon ecosystems rather than merely structural marine habitats.
Why it matters
If coral reefs are confirmed as substantial carbon sinks at a global scale, they may need to be incorporated into marine carbon accounting frameworks and climate mitigation strategies. This could also strengthen the economic and policy case for coral reef conservation beyond biodiversity and fisheries arguments.
A collaborative research team has revealed the long-overlooked carbon storage potential of coral reef ecosystems and how reef-dwelling fish, corals, and surface sediments jointly shape reef carbon reservoirs. The paper is published in the journal Advanced Science. The team was led by The Hong Kong University of Science and Technology (HKUST), the Institute of Zoology at the Chinese Academy of Sciences (IOZ-CAS) and the Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou) (GML).
