2020.10.09 14:30 | 周隆泉楼 B3-202 | 朱晶 | 夏季白令陆架的氮循环过程 | 陈光辉 |
张琨 | Primary Productivity and Uptake of New and Regenerated Forms of Nitrogen in 32nd Antarctic Research Expedition |
宁江豪 | Hotspots——Nitrogen fixation microorganisms associated with copepods in surface waters of the South China Sea |
报告提要 | 朱晶：1. 白令陆架西侧断面硝酸盐氮同位素和颗粒氮同位素的分布特征及影响因素.2. 白令陆架东西断面硝酸盐氮同位素和颗粒氮同位素的分布特征及影响因素. 张琨：The Antarctic Peninsula and its surrounding waters have rich nutrients and high productivity. N and P are rich enough to support productivity. Light intensity is the main factor influencing the primary production Primary productivity has a large change with latitude, so does the new productivity. 宁江豪：1. Determination and Analysis of nitrogen fixation rate associated with copepods in surface waters of the South China Sea. 2. Diazotroph diversity and geographic distribution associated with copepods in surface waters of the South China Sea. 3. Copepods (zooplankton) play an important role in the marine nitrogen cycle. |
2020.10.23 14:30 | 周隆泉楼 A3-206 | 陈光辉 | Trace AABW using 18O in prydz Bay and Dape Darnley | 李琦 |
申雅晴 | Calculation of N correlation fluxes in the upper layer of the mesoscale warm eddy over the northern South China Sea |
康佳雯 | The N cycle in the Antarctic Ocean |
报告提要 | 陈光辉：1. Feasibility analysis. 2. Ratio calculations of two sources of AABW in Pryda Bay and Dape Darnley. 申雅晴：1. Physical Properties of mesoscale eddies in the northern South China Sea. 2. Calculation method of N correlation fluxes. 康佳雯：1. Overview of Marine Nitrogen cycle. 2. Research status of N cycle in Antarctic Zone. |
2020.10.30 14:30 | 周隆泉楼 A3-206 | 徐超 | 从菲律宾海到南海西部0–750m水层硝酸盐浓度增加的可能原因 | 张欣如 |
李琦 | Analysis of the results of a method for 210Pb determination in biological samples |
冯娜 | Export flux of 234Th for tracing biological element in Daya Bay |
报告提要 | 徐超：从菲律宾海到南海西部0-750m水层硝酸盐浓度增加的可能原因. 李琦：Analysis of the results of a method for 210Pb determination in biological samples. 冯娜 ：1. Challenges of POC flux in continental shelf seas. 2. 234Th/238U disequilibria in Daya Bay.3. 234Th and POC flux in Daya Bay. |
2020.11.06 14:30 | 周隆泉楼 B3-202 | 王昕 | Apparent enhancement particle export in twilight zone of northern South China Sea revealed by 210Po/210Pb disequilibria and dissolved Fe | 杨紫菲 |
陈阳军 | Why PNM is ubiquitous in global oceans？ |
报告提要 | 王昕：1. A large deficiency of 210Po indicate active particle cycling in twilight water of NSCS. 2. Release of sedimentary porewater of continental margin noticeably increases the dissolved iron in NSCS. 3. Alone-slope transport by current interaction with steep topography was responsible for enhanced particle export in twilight zone of NSCS. 陈阳军：1. What is the formation mechanism of the PNM in the global ocean? 2. Why is ammonia oxidation dominated in the global ocean? |
