Dr. YANG Jinyu joined Xiamen University in May 2019. He is now an assistant professor of chemical oceanography at the State Key Laboratory of Marine Environmental Science (MEL, Xiamen University). Dr. Yang got his PhD in environmental science at Xiamen University in 2015, co-supervised by Prof. Minhan Dai and Prof. Shuh-Ji Kao. During his graduate studies, he stayed at Academia Sinica (Taipei) for two years as a visiting student. In 2015 he was an assistant research scientist at MEL. After receiving a postdoc fellowship from Korea in early 2016, he moved to Pohang University of Science and Technology (POSTECH) to work with Prof. Kitack Lee, a world-renowned marine chemist, for two and half years.
Dr. Yang’s research interests are the responses and variationsain marine particle dynamics and the marine nitrogen cycle under the anthropogenic and climate change forcings using stable isotope tools. His research focuses specifically on elemental transfer and transformation among different nitrogen species in the atmosphere and ocean, as well as coupling of biogenic elements in particles and its controlling mechanism.
Dr. Yang’s work is mainly field-oriented, with ongoing projects focused on the influences of external nitrogen inputs on particle export and carbon sequestration in oligotrophic oceans. He has published several papers regarding particulate nitrogen dynamics and atmospheric nitrogen deposition (AND) in the South China Sea (SCS). His findings clarify the major sources of AND in the SCS, and provides evidence of the anthropogenic signals recorded in the nitrate pool. His works also indicate that particulate nitrogen dynamics in the SCS are distinct from most marginal seas and other oligotrophic oceans, which have implications in reconstructing the past changes of the nitrogen cycle in other marginal seas. In addition, Dr. Yang is responsible for the Southeast Asian Time-series Study (SEATS) and setting up the platform for sediment trap mooring. The SEATS program collaborates with multidisciplinary groups in the MEL aims to describe a comprehensive conceptual diagram at a subtropical site representative of the OceMar in the North Pacific Ocean. The mooring system could provide samples for chemical and biological analyses and platform for hydrographic research.
