National Center for Earth-surface Dynamics 2: the past and future EarthChristopher Paola, Efi Foufoula-Georgiou, Patrick Hamilton, Vaughn VollerUniversity of Minnesota, EAR-1246761ABSTRACTThe National Center for Earth-surface Dynamics (NCED) is an NSF Science and Technology Center (STC) focused on predicting the evolution of the coupled geomorphic-ecological systems of the Earth?s surface. NCED created the first national center anywhere focused on the integrated Earth-surface environment, and sunset as an STC in July 2012. This grant is to continue a small core of the most successful and community-centric programs developed under NCED in a new format. Its goal is to perpetuate the legacy of NCED in an innovative form that will engage the broader research community by focusing activity around an annual research theme that will bring together experimental, theoretical, and field researchers. The funding will be used mainly to support young scientists, especially pre-tenure faculty, postdoctoral researchers, and graduate students. Beyond its direct research contributions, among NCED?s most important community benefits have been (1) its ?extended family? model for mentoring students and postdocs; (2) hosting community activities such as workshops and shared field and experimental facilities; (3) serving as a focal point to help catalyze and launch new programs ? for example, the new AGU focus group, the new journal JGR-ES, and the IYD, all launched during NCED?s tenure with leadership from NCED participants; (4) hosting focused, ambitious research activities that afforded opportunities for community participation through extended visits; (5) close integration of research with informal education and Native American education, by development of a long-term working partnership with key institutions and people; and (6) hosting workshops and summer institutes, both strongly focused on young scientists. With this grant, NCED2 is a set of linked programs; the central theme will be a program of research theme years focused on key emerging areas in Earth-surface Dynamics (ESD). The theme years will include workshops, experiments, postdoc opportunities, visitor programs from undergraduate through faculty level, and informal education and Native American activities. These linked program components will allow a broad range of ESD scientists to collaborate in new ways, enhancing and accelerating their individual efforts to advance ESD. The focus of NCED2 is embodied in the proposal title: the past and future Earth. Building on the legacy of the NCED STC, PIs work will be centered on predicting the Earth-surface environment, combining observations of modern and past surface systems, experiments, and a full spectrum of theoretical approaches. The proposed NCED2 would provide the ESD research community with a set of new ways to collaborate, through theme-year research with many points of entry: shared synthesis postdocs; visits by graduate and undergraduate students, and faculty, to take part in collaborative research and interact with new people, methods, and ideas; workshops; summer institutes; and a virtual research commons for informal exchange among the broad ESD community. It would provide access to experimental and other facilities not available at most institutions, and to the extensive network of researchers created in the ten years of the NCED STC. The research results will accelerate development of predictive Earth-surface dynamics, forming the basis for evaluating the future of the surface environment ? the arena for most life and human activity ? in a world of changing climate and growing human influence. The results will support decision-making on topics ranging from river restoration and management to rebuilding deltaic wetlands. By continuing the strong program NCED has built for informal education with the Science Museum of Minnesota (SMM), NCED2 will continue to provide a venue for energetic, multi-faceted, two-way communication about our planet?s dynamic surface with the public ? a program that has now reached international dimensions with the SMM-led Water Exhibition. Finally, NCED2 will continue its commitment to building bridges and partnerships with the Native American community through our Native American Water Resources, Manoomin, Climate Change Partnership, giiwed?anang Minnesota Undergraduate AISES Alliance, and Geoscience Alliance programs. The last of these in particular has now evolved to a national-scale program to foster Native American environmental education.

国家地球表面动力学中心2：过去和未来的地球克里斯托弗·保拉，埃菲·福福拉-乔治欧，帕特里克·汉密尔顿，明尼苏达大学沃恩·沃勒，EAR-1246761ABSTRACT国家地球表面动力学中心是美国国家科学基金会的一个科学技术中心，专注于预测地球表面耦合的地貌-生态系统的演变？S地表。NCED创建了世界上第一个专注于地球表面综合环境的国家中心，并于2012年7月作为STC成立了日落中心。这笔赠款是为了以一种新的形式继续NCED下开发的最成功和以社区为中心的一小部分核心项目。它的目标是以一种创新的形式延续NCED的遗产，通过围绕将汇集实验、理论和现场研究人员的年度研究主题开展活动，使更广泛的研究社区参与进来。这笔资金将主要用于支持年轻科学家，特别是终身教职前的教师、博士后研究人员和研究生。除了直接的研究贡献，在NCED中，S最重要的社区利益是：(1)它的大家庭？指导学生和博士后的模式；(2)主持社区活动，如研讨会和共享的现场和实验设施；(3)作为联络点，帮助催化和启动新项目？例如，新的AGU重点小组、新期刊《JGR-ES》和美洲土著教育年鉴都是在NCED？S任期内推出的，并在NCED参与者的领导下进行；(4)主办有重点的、雄心勃勃的研究活动，通过延长访问时间使社区有机会参与；(5)通过与主要机构和个人发展长期工作伙伴关系，将研究与非正规教育和美洲原住民教育紧密结合起来；以及(6)举办讲习班和暑期研习班，这两个活动都以青年科学家为重点。有了这笔赠款，NCED2是一套相互关联的计划；中心主题将是一个以地球表面动力学(ESD)关键新兴领域为重点的研究主题年计划。主题年将包括研讨会、实验、博士后机会、从本科生到教职员工的游客计划，以及非正式教育和美洲原住民活动。这些相互关联的计划组成部分将允许广泛的可持续发展教育科学家以新的方式进行合作，加强和加快他们推进可持续发展教育的个人努力。NCED2的重点体现在提案的标题：过去和未来的地球。在NCED STC遗留下来的基础上，PIS的工作将集中于预测地球表面环境，结合对现代和过去表面系统的观察、实验和全面的理论方法。拟议的NCED2将通过具有许多切入点的主题年研究，为可持续发展教育研究界提供一套新的合作方式：共享综合博士后；研究生和本科生以及教员访问，参与合作研究，并与新的人、方法和想法互动；讲习班；暑期研习班；以及一个虚拟研究共享空间，供广泛的可持续发展教育社区进行非正式交流。它将提供大多数机构没有的实验和其他设施，以及在NCED STC十年期间建立的广泛的研究人员网络。研究成果将加速地球表面动力学预测的发展，为评价未来地表环境奠定基础。大多数生命和人类活动的竞技场？在气候变化和人类影响力日益增长的世界里。研究结果将为从河流恢复和管理到重建三角洲湿地等主题的决策提供支持。通过继续NCED与明尼苏达州科学博物馆(SMM)为非正规教育而打造的强大项目，NCED2将继续提供一个关于我们的星球？S动态表面与公众进行充满活力的、多方面的、双向的交流的场所。通过SMM主导的水展，该项目现已达到国际规模。最后，NCED2将继续致力于通过我们的美洲原住民水资源、Manoomin、气候变化伙伴关系、GIWED？Anang明尼苏达州本科生联盟和地球科学联盟计划，与美国原住民社区建立桥梁和伙伴关系。其中最后一个特别是现在已经发展成为一个全国性的项目，以促进美洲原住民的环境教育。
