University of Minnesota Duluth R/V Blue Heron Ship Operations - CY 2018-2022

概述：该提案是为RV Blue Heron船上运营提供资金的请求，RV Blue Heron是明尼苏达大学拥有的86英尺研究船，由大湖天文台（LLO）运营。该奖项将涵盖2018年至2022年的野外季节，年度报告提供2019年至2022年季节的详细信息。在2018日历年，两个NSF同行评审资助的项目要求该船22天：* 塞缪尔·凯利（明尼苏达大学）：9天，“合作研究：海岸惯性带动力学：在自然实验室中分离强迫和自由响应”（OCE/PO-1635560）。Tedy Ozersky（明尼苏达大学）：13天，“耦合的C-N-P循环对底栖生物群落剧烈变化的生态系统尺度响应：上五大湖”（OCE/CO-1737368）。智力成果：在R/V蓝鹭上完成的工作是为了支持NSF资助的研究计划。这些研究项目的智力价值通常作为向NSF提交的研究提案的一部分单独进行审查。Kelly的项目（OCE/PO-1635560）将利用真实的数值模拟和对沿湖泊海岸线的风、湍流和近惯性波的广泛直接观测以及粗糙的海岸测深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斑驴贻贝对五大湖的生物学和化学的影响。在淡水系统中，底栖生物群落对生态系统水平上的碳、氮和磷的影响研究不足，这些营养物质如何受到德氏贻贝入侵的影响的机制尚不清楚。Ozersky的工作将促进对五大湖生态的理解，并改进水生生态系统中沉积物-水柱相互作用的模型。这两个项目将使学生参与研究的各个方面。除了促进五大湖上的研究项目外，R/V Blue Heron在这一年中有许多教育或“班级巡航”（2017年期间有9次），使本科生和研究生能够参与研究船上的工作，这些研究船上的设备通常用于大型远洋研究船。除了班级巡航，本科生和研究生几乎参加每一个RV蓝鹭巡航作为研究助理，有时，首席科学家。此外，在过去的四年里，我们还举办了首席科学家培训巡航，在此期间，早期职业科学家（高年级研究生，博士后和一年级教师）接受了有关UNOLS的教育，并直接沉浸在规划和进行科学考察中。码头边，我们给图尔斯参观明尼苏达大学的学生，本科生从其他机构，并已建立了一个码头边每月参观和研讨会系列为广大市民。在过去的五年里，大约有4,500名公众参观了该船作为研讨会系列的一部分。关于具体的更广泛的影响，凯利的项目（OCE/PO-1635560）将有助于改善沿海环境中使用的数值模型的解释。Ozersky的项目（OCE/CO-1737368）将为教育工作者和公众创建在线内容，并将在杜卢斯的大湖水族馆、密尔沃基的探索世界科学博物馆和芝加哥的谢德水族馆和NavyPier举办外展活动。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
