South China Sea coral reefs reveal carbon stores rivaling mangroves and seagrasses

Phys · · 542 words · By Hong Kong University; Technology

A research team led by institutions in Hong Kong and mainland China has published a study in Advanced Science regarding the carbon storage potential of coral reefs in the South China Sea. The study suggests that these reefs store significant amounts of carbon, primarily in sediments, and emphasizes the role of reef fish and corals in this process.
