MARGINS Successor Planning Workshop

为一个海洋地球科学界范围的讲习班提供了资金，以审议和讨论MARGINS方案的未来。在2009年2月对该计划进行积极的十年审查之后，MARGINS指导委员会（MSC）被要求召开一次社区范围的研讨会，旨在确定和阐明潜在的后续计划将解决的关键科学挑战，并制定其结构。一份科学计划草案将在这次会议的基础上产生？的结果，这将是由NSF使用作为基础，决定是否后续计划将被授权。研讨会计划于2010年2月在德克萨斯州的圣安东尼奥举行。海安会设想的是，MARGINS的后继者将调查在广泛的时间尺度上建立和修改大陆边的耦合地球动力学，表面和气候过程。这样一个程序将有边缘的演变和动态，地层结构的建设，经济资源的积累，相关的地质灾害，气候变化和环境管理的影响的应用。解决这种复杂的耦合系统需要一个综合的方法，我们设想了广泛的研究结合实地研究结构和构造，地球化学，地球物理学，沉积学和地层学，但也纳入实验，分析和数值模拟调查。该计划将涉及大型两栖实地项目和较小的重点领域和实验室研究。为了使该计划取得成功，应该在广泛的社区支持下制定一个明确而有重点的科学计划。研讨会希望为这一计划奠定基础。活动大陆边缘是一些最引人注目的地质现象的来源，包括地震，山体滑坡和火山爆发。大陆边不断增长的人口也受到长期环境影响，如沿海淹没、侵蚀或风暴影响引起的土地使用变化。大陆边也是蕴藏丰富经济资源的地方，今后要利用这些资源，就必须全面了解这些矿床的起源和分布。讲习班的一项重要成果将是建立一个科学调查结构，以处理这些专题问题，并向公众传达关于大陆边过程和危害的连贯一致的信息。它还将提供一个连贯的教育计划，以补充后续计划的结构，基于目前的本科生为基础的计划。

Funds are provided for a marine geosciences community-wide workshop to consider and discuss the future of the MARGINS Program. In the aftermath of a positive Decadal Review of the program in February 2009, the MARGINS Steering Committee (MSC) was asked to convene a community-wide workshop, intended to identify and elucidate key scientific challenges that a potential successor program would address, and to map out its structure. A draft Science Plan would emerge based upon that meeting?s result, which would then be used by NSF as a basis for deciding whether a successor program will be authorized. The workshop is planned for February 2010 in San Antonio, TX. It is envisioned by the MSC that a successor to MARGINS that will investigate the coupled geodynamic, surficial, and climatic processes that build and modify continental margins over a wide range of timescales. Such a program will have applications to margin evolution and dynamics, construction of stratigraphic architecture, and implications for accumulation of economic resources, associated geologic hazards, climate change and environmental management. Addressing such complex coupled systems requires an integrated approach, and we envision a broad range of studies combining field research in structure and tectonics, geochemistry, geophysics, sedimentology and stratigraphy, but also incorporating experimental, analytical and numerical modeling investigations. The program will involve large amphibious field programs and smaller focused field and lab-based studies. In order for the program to succeed, a clear and focused Science Plan should be formed, with broad community support. The workshop hopes to lay the groundwork for such a plan.Broader Impacts. Active continental margins are the sources of some of the most dramatic geologic phenomena, including earthquakes, landslides, and volcanic eruptions. The growing populations on continental margins are also subject to longer-term environmental impacts, such as land-use changes induced by coastal submergence, erosion, or storm effects. Continental margins are also the repository of abundant economic resources, and an integrated understanding of the origin and distribution of these deposits is necessary for accessing them in the future. An important outcome of the workshop will be a structure for scientific investigations that can address such topical issues, and convey coherent information about continental margin processes and hazards to the general public. It will also provide structure for a coherent Education Program to complement a successor program, based on the undergraduate-based program in place currently.
