On February 10, 2022, Communications Earth & Environment, a new journal under the Nature, published online the latest research results of Zhang Xi, a PhD student in the College of Marine Sciences, SHOU, on black carbon in hadal zone, The hadal zone is an important and heterogeneous sink of black carbon in the ocean. Zhang Xi, under the advice of Xu Yunping, a researcher in the College of Marine Science, has reported the source, distribution and burial flux of the hadal zone sink of black carbon for the first time in the world. This is another important research progress in the field of hadal science after the group reported the oceanic trench mercury pollution study in PNAS in 2021.

Zhang Xi is the co-first author of the paper, and researcher Xu Yunping and Dr. Xiao Wenjie (now a postdoctoral fellow at SUST) are the co-first and corresponding authors. Professor Fang Jiasong, Associate Researcher Luo Min, Dr. Fang Yin from SHOU and collaborators from Ocean University of China, Qingdao National Laboratory of Marine Science and Technology, Southern University of Science and Technology, University of Southern Denmark, Japan Marine Science and Technology Center, and National Institute for Water and Atmospheric Research, New Zealand participated in the work. The research was supported by the National Natural Science Foundation of China, the Open Fund of the State Key Laboratory of Estuarine and Coastal Sciences, East China Normal University, the Danish National Research Foundation, and the Open Fund of Shanghai Sheshan National Field Science Observatory. The research voyages was funded by the Shanghai Science and Technology Commission, the European Union Research Fund, and the National Institute for Water and Atmospheric Research, New Zealand.
