The Institute of Oceanology of the Chinese Academy of Sciences has triumphantly deployed its comprehensive synchronous observation buoy system designed for extensive profiles in the vital layer of ocean-air interaction. This groundbreaking system has been positioned at a depth of 3500 meters in the South China Sea, where it has commenced a year-long sea trial operation. Capable of functioning in the harshest marine environments, this system offers comprehensive and synchronized observations of the atmosphere, interface, and underwater environment. It bridges a significant technological gap in buoy observation for great water depths and extensive profiles, thereby providing vital support for marine scientific research and environmental protection efforts.
