Lateral downslope transport and tentative sedimentary organic carbon box model in the southern Yap Trench, western Pacific Ocean
Dong Li, Jun Zhao, Chenggang Liu, Jianming Pan, Ji Hu
2023, 42(1): 61-74. doi: 10.1007/s13131-022-2043-z
Abstract:
Sediment collapse and subsequent lateral downslope migration play important roles in shaping the habitats and regulating sedimentary organic carbon (SOC) cycling in hadal trenches. In this study, three sediment cores were collected using a human-occu...
Comparative assessment of nitrogen fixation rate by 15N2 tracer assays in the South China Sea
Danyang Li, Minfang Zheng, Yusheng Qiu, Limin Lai, Nengwang Chen, Hongmei Jing, Run Zhang, Min Chen
2023, 42(1): 75-82. doi: 10.1007/s13131-022-2092-3
Abstract:
Nitrogen fixation is one of the most important sources of new nitrogen in the ocean and thus profoundly affects the nitrogen and carbon biogeochemical processes. The distribution, controlling factors, and flux of N2 fixation in the global ocean remai...
Spatiotemporal changes of biogenic elements in the Changjiang River Estuary and adjacent waters in summer over the last decade
Lu Yang, Yujia Zhang, Xiaoli Wang, Qiulu Wang, Long He, Xiao Li
2023, 42(1): 83-90. doi: 10.1007/s13131-022-2104-3
Abstract:
The long-term spatiotemporal changes of surface biogenic elements in the Changjiang River Estuary and adjacent waters during the summer of 2008−2016 were analyzed in this study. The concentrations of dissolved inorganic nitrogen (DIN), soluble reacti...
Sedimentary record of climate change in a high latitude fjord—Kongsfjord
Hang Wu, Binbin Deng, Jinlong Wang, Sheng Zeng, Juan Du, Peng Yu, Qianqian Bi, Jinzhou Du
2023, 42(1): 91-102. doi: 10.1007/s13131-022-2098-x
Abstract:
The sedimentary record of climate change in the Arctic region is useful for understanding global warming. Kongsfjord is located in the subpolar region of the Arctic and is a suitable site for studying climate change. Glacier retreat is occurring in t...
Application of an optical nitrate profiler to high- and low-turbidity coastal shelf waters
Yanpei Zhuang, Yangjie Li, Xizhen Liu, Shichao Tian, Bin Wang, Zhongqiang Ji, Haiyan Jin, Jianfang Chen
