Recently, the final acceptance meeting for project "Development of Submarine Cold Seep In-situ Intelligent Monitoring /Detection Station" fund from the Guangdong Province Key R&D Program was held in Nansha, Guangzhou. The meeting was organized by the Guangdong Provincial Science and Technology Infrastructure Platform Center under the Department of Science and Technology of Guangdong Province Gov.. More than 30 attendees were present included 7 experts in the relevant disciplines, the Project principal Professor Yang Shengxiong, project team members, and representatives from relevant administrative authorities.
The expert acceptance panel listened to the report on the project implementation and completion, reviewed the acceptance documents, and conducted an on-site inspection of the project achievements. The panel confirmed that the project has fulfilled all prescribed tasks and indicators and achieved expected outcomes, unanimously approving its successful final acceptance.
Led by the Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou) and jointly implemented by the Guangzhou Marine Geological Survey, the project has developed a world-leading in-situ intelligent monitoring and detecting station for deep-sea cold seeps. The station is capable of operating at a depth of 3,000 meters and running autonomously for six consecutive months. It has made innovative breakthroughs in core technologies, including long-term time-series multi-parameter monitoring and detecting onthe deep seafloor, as well as intelligent deep water and plume suction filtration deposit samples collection. The prototype completed a 193-days in-situ seafloor trial in the northern South China Sea, acquiring substantial monitoring data and samples, achieving a 100% completion rate for long-term observation tasks. The Technology Readiness Level (TRL) was elevated from Level 3 to Level 7. This monitoring and detecting station has been successfully applied to the investigation such as the Shiptime Sharing Project of the NSFC in the SCS and supporting the site evaluation for the source fire collection area for the 15th National Games, yielding significant social and economic benefits.
The achievements of this project have broad application prospects and can be applied to fields including deep-sea resource exploration, ecological environments, and earth systematic science research. Going forward, the research team will continue to optimize core technologies, expand its multi-scenario application capabilities, accelerate the transformation of research achievements and functional upgrading of the monitoring station, contributing to the developments of the deep sea Science and Technology in China.
