On March 26, the fifth meeting of the first academic committee of the Observation and Research Station of Global Ocean Argo System (Hangzhou), MNR (“Argo Field Station”) was held in Hangzhou. Academician Chen Dake, Deputy Director Mei Xianjun from the SIO, and more than 30 experts and scholars from units such as the National Marine Environmental Forecasting Center, relevant institutes of the Chinese Academy of Sciences, Ocean University of China and Xiamen University, attended the meeting.

Academician Chen Dake, the director of the academic committee of the Argo Field Station, chaired the meeting, and Station Director Liu Zenghong delivered the 2024 annual work report. In 2024, the Argo Field Station deployed 32 autonomous profiling floats in the Northwest Pacific and Indian Ocean relying on various projects, and incorporated 16 floats deployed by other domestic units into the China Argo Program, maintaining a China Argo observation network composed of over 70 floats. It developed a deep-sea CTD salinity correction model and performed delayed correction of salinity data from the deep-sea Xuanwu profiling float deployed by Laoshan Laboratory, greatly supporting the construction of China’s deep-sea Argo regional observation network. Multiple national key research and development programs, natural science foundation projects and research topics under study at the Argo Field Station progress smoothly, contributing to the research and development of domestic biogeochemical sensors and new floats. The station has newly been approved as a Model Worker & Craftsman Innovation Workshop under the Zhejiang Provincial Defense Science and Industry System, with one person selected as a technology leader of the Ministry of Natural Resources and another receiving funding from the Provincial Outstanding Youth Science Foundation Project. The academic committee fully affirmed the achievements of the Argo Field Station in the past year in areas such as the construction of China’s profiling float observation network, data product development, open sharing and team building, discussed the station’s development direction, business operation, special float data sharing and the integration of China’s Argo Program into the operational system, and put forward opinions and suggestions.

At the meeting, Researcher Xing Xiaogang, deputy director of the Argo Field Station, Researcher Cheng Lijing, a visiting expert, and Associate Professor Li Hong respectively presented three academic reports titled “Progress in the Development of Domestically Produced BGC-Argo Floats and Biogeochemical Sensors”, “Construction of a Global Ocean Dissolved Oxygen Observation Dataset”, and “Changes in Western Boundary Currents with Horizontal Resolution - An Observational Perspective”, and conducted exchanges and discussions with the experts present.
