Cooperated with Prof. Thomas Bianchi's team from University of Florida, Prof. Zhigang Yu's team made a great progress on the effect of particle density on the sources, distribution and degradation of sedimentary organic carbon in the Changjiang Estuary and adjacent shelf. The result was published in Chemical Geology (impact factor: 3.482) recently. (Jinpeng Wang, Peng Yao*, Thomas S. Bianchi, Dong Li, Bin Zhao, Xingqian Cui, Huihui Pan, Tingting Zhang, Zhigang Yu.The effect of particle density on the sources, distribution, and degradation of sedimentary organic carbon in the Changjiang Estuary and adjacent shelf.Chemical Geology, 2015, 402:52-67.)
