Workshop to assess "Recent Changes in the Biogeochemistry of the Great Lakes System (BOGLS)"

该奖项将支持举办一个讲习班，以评估科学研究需要，以解决过去五十年来劳伦蒂五大湖发生的重大生物地球化学变化，这是一个特别容易受到非本土物种破坏的生态系统。研讨会将于2013年3月11日至13日在底特律的韦恩州立大学举行。这将是第一次评估自20世纪80年代中期引入斑马贻贝等入侵物种以来出现的生物地球化学变化。尽管有近200个非本土入侵者的漫长历史，但在过去的20-30年里，珠江口贻贝对五大湖下游的快速、广泛的殖民和改造已经从根本上改变了生物地球化学重要物质(BIM)的循环，并可以说导致了近年来历史上最大的五大湖生物地球化学变化。这次讲习班的目的是以科学计划的形式记录这些变化和与之相关的基本科学问题，该计划将被广泛传播。研讨会的摘要将被综合并发表在EOS上。智慧的优点：这是对五大湖淡水系统不断变化的生物地球化学进行的第一次全流域评估。查明引起和正在引起这些变化的过程将引起全球水生地球化学界的广泛兴趣。与至少三个联邦机构合作，积极参与淡水研究的八所大学的参与和赞助证明了讲习班的必要性和及时性。更广泛的影响：大约3700万人生活在五大湖盆地，2600万人依赖五大湖提供饮用水。水质不仅直接影响人类健康，而且还影响农业、渔业、制造业、航运和旅游业的就业。讲习班的成果与世界各地大型淡水湖的科学和管理有关，如东非裂谷湖、贝加尔湖、坦噶尼喀湖和加拿大内陆大湖(大熊、大奴隶、温尼伯和阿萨巴斯卡)。研讨会的讨论将有益于参加的研究生，会议可能提供一个将整个中西部的研究生教育联系起来的平台。

This award will support a workshop to assess scientific research needs to address major biogeochemical changes that have been taken place over the past five decades in the Laurentide Great Lakes, an ecosystem particularly susceptible to disruption by non-native species. The workshop will be held at Wayne State University in Detroit on March 11-13, 2013. It will be the first of its kind to assess the biogeochemical changes that have arisen since the introduction of invasive species such as zebra mussels which arrived in mid-1980s. Despite a long history of nearly 200 non-native invaders, the rapid, extensive colonization and reengineering of the lower Great Lakes by dreissenid mussels in the last 20-30 years has fundamentally altered the cycling of biogeochemically important materials (BIMs) and resulted arguably in the largest biogeochemical shift in the Lakes in recent history. The purpose of this workshop is to document these changes and the fundamental scientific questions associated with them in the form of a Science Plan, which will be widely disseminated. A summary of the workshop will be synthesized and published in EOS.Intellectual Merit: This is the first basin-wide assessment of the changing biogeochemistry of the Great Lakes freshwater system. The identification of the processes that have caused and are causing these changes will be of broad interest to the global aquatic geochemical community. The participation and sponsorship by eight universities that are actively involved with freshwater research in partnership with at least three federal agencies is a testament to the need and timeliness of the workshop. Broader Impact: Approximately 37 million people live in the Great Lakes basin and 26 million people rely on the Great Lakes for their drinking water. The water quality has direct impact not only on human health but also on jobs in agriculture, fisheries, manufacturing, shipping, and tourism. The outcome of the workshop is relevant to the science and management of large freshwater lakes around the world, such as the East African rift lakes, Lake Baikal, Lake Tanganyika, and the Canadian interior great lakes (Great Bear, Great Slave, Winnipeg, and Athabasca). The deliberations of the workshop will be beneficial to the participating graduate students and the meeting may provide a platform for linking graduate education across the Midwest.
