| 1 | Reduced inorganic sulfur in the sediments of the Yellow Sea and East China Sea显示文摘Cold diffusion methods are used to separate and quantify the three reduced inorganic sulfur species into acid volatile sulfide(AVS), pyrite–S and element sulfur(ES) in the sediments of the Yellow and East China Seas. The results show that up to 25.02 μmol/g of AVS, 113.1 μmol/g of pyrite–S and 44.4 μmol/g of ES are observed in the sediments of the Yellow Sea and East China Sea. Pyrite–S is the predominant sulfide mineral in the sediments, while the concentration of AVS is quite low at most stations in the study area. The amounts and reactivity of organic matter are the primary limited factor for the sulfide formation, while an iron limitation and a sulfate limitation are not observed in the sediments of the Yellow Sea and East China Sea. The irregular profiles of the three reduced inorganic sulfur species also reflected the comprehensive influence of sediment composition and sedimentation rates. | KANG Xuming LIU Sumei ZHANG Guoling | 2014 | Acta Oceanologica Sinica2014，33，9： | 6 |
| 2 | The sources and composition of organic matter in sediments of the Jiaozhou Bay:implications for environmental changes on a centennial time scale显示文摘The Jiaozhou Bay is characterized by heavy eutrophication that is associated with intensive anthropogenic activities. Four core sediments from the Jiaozhou Bay are analyzed using bulk technologies, including sedimentary total organic carbon(TOC), total nitrogen(TN), the stable carbon(δ^(13)C) and nitrogen(δ^(15) N) isotopic composition to obtain the comprehensive understanding of the source and composition of sedimentary organic matter and further shed light on the environmental changes of the Jiaozhou Bay on a centennial time scale.Results suggest that the TOC and TN concentrations increase in the upper core, having indicated a probable eutrophication process since the 1920 s in the inner bay and the 2000 s in the bay mouth. The TOC and TN concentrations outside the bay have also changed since 1916 owing to the variation of terrigenous input.Considering TOC/TN ratio, δ^(13) C and δ^(15) N, it can be concluded there is a mixture of terrigenous and marine organic matter sources in the study area. A simple two end-member(terrigenous and marine) mixing model usingδ^(13) C indicats that 45%–79% of TOC in the Jiaozhou Bay is from the marine source. The environmental changes of the Jiaozhou Bay are recorded by geochemical proxies, which are influenced by the intensive anthropogenic activities(e.g., extensive use of fertilizers, and discharge of sewage) and climate changes(e.g., rainfall). | KANG Xuming SONG Jinming YUAN Huamao LI Xuegang LI Ning DUAN Liqin | 2017 | Acta Oceanologica Sinica2017，36，11： | 5 |
