Overview:This proposal is a request for funds for Shipboard Operations on the RV Blue Heron, an 86ft-researchvessel that is owned by the University of Minnesota and operated by the Large Lakes Observatory (LLO).The award will cover the 2018 to 2022 field seasons, with annual reports providing detailed informationfor the 2019 to 2022 seasons. During the 2018 calendar year, two NSF-peered reviewed funded projects have requestedthe ship for 22 days:* Samuel Kelly (Univ. of Minnesota): 9 days, 'Collaborative research: Coastal inertial-band dynamics:separating forced and free responses in a natural laboratory' (OCE/PO-1635560).* Tedy Ozersky (Univ. of Minnesota): 13 days, 'Ecosystem-scale responses of coupled C-N-P cycles todramatic shifts in benthic communities: the Upper Great Lakes' (OCE/CO-1737368).Intellectual Merit:Work done aboard the R/V Blue Heron is in support of NSF funded research programs. The intellectualmerit for these research programs is normally reviewed separately as part of a research proposal to NSF.Kelly's project (OCE/PO-1635560) will quantify coastal kinetic-energy pathways using realisticnumerical simulations and extensive direct observations of winds, turbulence and near-inertial wavesalong lacustrine coastlines and rough coastal bathymetry. The project will improve our understanding ofnear inertial motions throughout the coastal ocean and in large lakes. Ozersky's project (OCE/CO-1737368) will study the effects of invasive zebra and quagga mussels on the biology and chemistry of theGreat Lakes. The impact of benthic communities on carbon, nitrogen and phosphorus in freshwatersystems at the ecosystem level are understudied and the mechanisms for how these nutrients are affectedby the introduction of dreissenid mussel invasives are unclear. Ozersky's work will advance theunderstanding of the ecology of the Great Lakes and improve models of sediment-water columninteractions in aquatic ecosystems.The two projects will involve students in all aspects of the research. In addition to facilitating researchprojects on the Great Lakes, the R/V Blue Heron has numerous educational or 'class cruises' during theyear (9 during 2017), enabling undergraduate and graduate students to participate in work on a researchvessel with equipment typically used on larger, ocean going, research vessels. Beyond the class cruises,undergraduate and graduate students participate on almost every RV Blue Heron cruise as researchassistants and, sometimes, chief scientist. Additionally, we have hosted Chief Scientist Training cruisesover the last four years, during which early career scientists (senior graduate students, post-docs, and 1styear faculty) are educated about UNOLS and directly immersed in planning and undertaking a scientificexpedition. Dockside, we give tours to University of Minnesota students, undergraduates from otherinstitutions and have established a dock-side monthly tour and seminar series for members of the generalpublic. Over the last five years, approximately 4,500 members of the public have toured the vessel aspart of the seminar series.Regarding specific broader impacts, Kelly's project (OCE/PO-1635560) will help improve theinterpretation of numerical models used in coastal settings. Ozersky's project (OCE/CO-1737368) willcreate online content for educators and the public, and will host outreach events at Duluth's Great LakesAquarium, Milwaukee's Discovery World Science Museum and Chicago's Shedd Aquarium and NavyPier.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

概述：这项提案是为RV Blue Heron上的船上行动申请资金，RV Blue Heron是一艘86英尺长的研究船，由明尼苏达大学拥有，由大湖天文台(LLO)运营。奖励将涵盖2018至2022年的野外季节，年度报告提供2019年至2022年的详细信息。在2018年历年，两个由NSF同行审查的资助项目申请了22天的船期：*Samuel Kelly(Univ.明尼苏达州大学)：9天，“合作研究：沿海惯性带动力学：在自然实验室中分离强迫和自由响应”(OCE/PO-1635560)。明尼苏达州)：13天，“C-N-P耦合循环对五大湖上游底栖群落戏剧性变化的生态系统规模响应”(OCE/CO-1737368)。智力优势：在R/V蓝鹭上所做的工作是为了支持国家科学基金会资助的研究项目。这些研究项目的学术价值通常是作为国家科学基金会研究建议的一部分单独审查的。凯利的项目(OCE/PO-1635560)将使用真实的数值模拟和对湖泊海岸线和粗糙海岸水深的风、湍流和近惯性波的广泛直接观测来量化海岸动能路径。该项目将提高我们对沿海海洋和大型湖泊中近惯性运动的理解。Ozersky的项目(OCE/CO-1737368)将研究入侵的斑马和Quagga贻贝对五大湖生物和化学的影响。在生态系统水平上，底栖动物群落对淡水系统中碳、氮和磷的影响还没有得到充分的研究，而这些营养物质是如何因淡水贝类入侵而受到影响的机制尚不清楚。Ozersky的工作将促进对五大湖生态学的理解，并改进水生生态系统中沉积物-水柱相互作用的模型。这两个项目将让学生参与到研究的各个方面。除了促进五大湖的研究项目外，R/V蓝鹭在这一年(2017年有9次)有许多教育或“班级航行”，使本科生和研究生能够利用通常在更大的远洋科考船上使用的设备参与研究船的工作。除了班级巡航外，本科生和研究生几乎参加了每一次房车蓝鹭巡航，作为研究助理，有时还担任首席科学家。此外，在过去四年中，我们主办了首席科学家培训游轮，在此期间，早期职业科学家(高级研究生、博士后和一年级教师)接受了关于联合国日内瓦办事处的教育，并直接参与了科学考察的规划和开展。在码头，我们为明尼苏达大学的学生和其他机构的本科生提供旅游，并为普通公众建立了码头月度旅游和研讨会系列。在过去的五年里，作为研讨会系列的一部分，大约有4,500名公众参观了这艘船。关于具体的更广泛的影响，凯利的项目(OCE/PO-1635560)将有助于改进沿海地区使用的数值模式的解释。Ozersky的项目(OCE/CO-1737368)将为教育工作者和公众创建在线内容，并将在德卢斯的大湖水族馆、密尔沃基的发现世界科学博物馆和芝加哥的Shedd水族馆和NavyPier举办外联活动。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
