IMBeR Eutrophication Study Group (ESG) held its third meeting via video on 20 January 2023 (19 January according to North American time), right before the Spring Festival, with 13 experts participating online. Co-Chair Prof. Peter Thompson, from CSIRO (Australia), started the meeting by warmly welcoming everyone. Before the reports, the group reviewed the presentations from the last meeting together, and Peter encouraged everyone to refine the potential outputs after each meeting. Also, Peter mentioned the UN Biodiversity Conference (COP 15) held in December 2022, and proposed this group to engage a lot harder with the Convention on Biological Diversity.



In this meeting, two experts were invited to give the IMBeR-ESG-Talks. Centering on the long-term nitrogen management and the recent challenges facing Tampa Bay in western Florida, U.S., Ed Sherwood, Executive Director of the Tampa Bay Estuary Program (TBEP), introduced the strategies and actions taken through this program, presented its fruitful achievements on seagrass coverage recovery in the past three decades, and introduced potential solutions to the current challenges caused by wastewater from legacy mining facilities in this region. 



Then, Co-Chair Prof. Dongyan Liu, from SKLEC of ECNU (China), gave the second talk of this meeting. Using Sishili Bay, a typical temperate bay of China located in Yantai, Shandong Province, as an example, Prof. Liu presented the trends and patterns of eutrophication in coastal waters of China, and illustrated the N-Si coupling pathway in diatom at the cellular level that explained the shifts in diatom and dinoflagellate caused by nutrient supply ratios. The attendees exchanged ideas on the content of the reports, and proposed suggestions based on the tangible outputs from this group.




The fourth meeting of the IMBeR Eutrophication Study Group will be held in March 2023. We are eagerly looking forward to updating you soon. The video of the IMeR-ESG-Talks will be compiled and released online after the group’s output is published.


会议回顾:IMBeR富营养化工作组第三次线上会议成功举办


2023120日(北美时间119日),时值新春佳节来临之际,IMBeR富营养化工作组(Eutrophication Study GroupESG)成功举办第三次会议,13位专家在线出席。来自澳大利亚联邦科学与工业研究组织(CSIRO, Australia)的Peter Thompson教授(工作组联合主席)主持会议,并向所有与会者表示热烈欢迎。报告开始前,工作组共同回顾了第二次会议的主要内容,Peter Thompson教授鼓励工作组成员在每次会后就潜在产出进行完善。此外,Peter Thompson教授还提到了于202212月举行的联合国生物多样性大会(UN Biodiversity Conference, COP15),并提议工作组更积极地参与《生物多样性公约》(Convention on Biological Diversity, CBD)相关监测评估的建设进程。

本次会议邀请了两位专家作IMBeR富营养化主题系列报告(IMBeR-ESG-Talks)。坦帕湾河口计划(Tampa Bay Estuary Program, TBEP)执行主任Ed Sherwood的报告围绕美国佛罗里达州西部坦帕湾的长期氮管理与当前面临的新挑战展开。Ed介绍了TBEP采取的治理策略与行动,展示了过去三十年该计划修复海草床的成效,并提出该区域当前面临的遗留采矿设施污水泄露的挑战和潜在解决方案。而后,来自华东师范大学河口海岸学国家重点实验室(SKLEC of ECNU, China)的刘东艳研究员带来了第二场报告。以中国山东烟台的四十里湾这一典型温带海湾为例,刘东艳研究员介绍了中国沿海水域富营养化的时空分布特征,并从细胞水平上阐明了硅藻中的N-Si耦合途径,进而可以解释由于营养盐比值变化而引发的硅藻和甲藻群落演替。与会人员围绕报告内容进行了交流,并立足工作组实际产出提出建议。

富营养化工作组第四次会议将于3月举行,工作组热切期盼与大家分享更多进展。IMBeR-ESG-Talks学术报告录像将在工作组成果发表后整理上线。
