This is an award to support the participation of 20 U.S. graduate students, post-doctoral fellows and early-career investigators in the American Geophysical Union (AGU) Chapman conference that will take place in Flagstaff, AZ on March 16-20, 2020 to discuss, develop and test conceptual models of distributed volcanism. Focus by the scientific community is especially important now because of continuing growth of cities, communities, and critical infrastructure within sparsely monitored volcanic fields. Most sub-aerial volcanoes are found in widely distributed volcanic fields made up of tens to hundreds of vents, which comprise a huge range of eruption-styles and landforms – from scoria cones to calderas – and which are situated in a variety of tectonic settings. The conference will provide needed background and focus on the problem of distributed, monogenetic volcanism, summarizing current research directions. In the western U.S., widely distributed volcanic fields are virtually unmonitored. Internationally, many cities (e.g., Auckland, Mexico City) are built on geologically active distributed volcanic fields. Great strides have been made in understanding the origins of magmas in these volcanic fields, their large- scale transport across the lithosphere, and statistical models of their eruption have been developed. Yet very fundamental questions remain about this most common style of volcanism. The conference is structured to provide networking activities and related discussions as well as to introduce early career participants to some of the most fascinating volcanic fields in the western U.S. This AGU Chapman conference on distributed volcanism is structured to encourage interdisciplinary contacts and thinking, in diverse fields such as geochemistry, geophysics, and volcano science. Themes to be address are whether the geophysical monitoring techniques and models (e.g., robust seismic and deformation monitoring) developed to monitor unrest elsewhere will work in volcanic fields. Also, of interest, the conference will touch on how scientists can couple geochemical and geophysical models for magma ascent in small-volume systems. Currently, there is no community consensus on the appropriate response to unrest in volcanic fields and associated hazards, and how these differ from arc composite volcanoes. It is expected that this conference will be of great benefit to early career scientists. It is expected that they will contribute substantially to all phases of the meeting, including giving invited talks, posters, participating in workshop break-out sessions and discussions during the post-meeting field trip to the nearby Springerville volcanic field. Specifically early career scientists will benefit in three ways: (1) at the conference they will participate in discussions and presentations about the cutting-edge science happening to understand volcanic fields, (2) they will learn about collaboration opportunities with USGS colleagues, who are deeply involved in the organization of the meeting, and with international colleagues, (3) they will learn how their disciplinary research fits with other science agendas related to volcanic fields, broadening the scope and impact of their own investigations. The discussions and outcomes of the conference will have direct impact on communities living with distributed volcanism throughout the western U.S. and the world.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.

该奖项旨在支持 20 名美国研究生、博士后研究员和早期职业研究人员参加将于 2020 年 3 月 16 日至 20 日在亚利桑那州弗拉格斯塔夫举行的美国地球物理联盟 (AGU) 查普曼会议，讨论开发和测试分布式火山活动的概念模型现在尤其重要，因为城市、社区和关键基础设施在监测稀疏的火山区域内不断发展。大多数地下火山都分布在由数十到数百个喷口组成的广泛分布的火山场中，这些火山场包括从火山渣锥到破火山口的各种喷发类型和地貌，并且位于各种构造环境中。会议将提供所需的背景知识，并重点关注分布式、单生火山作用问题，总结当前的研究方向。在美国西部，广泛分布的火山场实际上是存在的。在国际上，许多城市（例如奥克兰、墨西哥城）都建在地质活跃的分布火山田上，在了解这些火山田中岩浆的起源、岩浆在岩石圈中的大规模迁移和统计方面已经取得了长足的进步。然而，关于这种最常见的火山活动的非常基本的问题仍然存在，该会议的目的是提供网络活动和相关讨论，并向一些早期职业参与者介绍。本次 AGU 查普曼分布式火山会议旨在鼓励地球化学、地球物理学和火山科学等不同领域的跨学科接触和思考。会议主题是地球物理监测技术和火山学。为监测其他地方的动乱而开发的模型（例如，强大的地震和变形监测）将在火山领域发挥作用。此外，有趣的是，会议将讨论科学家如何耦合。小体积系统中岩浆上升的地球化学和地球物理模型目前，对于火山田动荡和相关灾害的适当应对措施以及这些与弧复合火山的不同之处，尚未达成共识。预计他们将为会议的各个阶段做出重大贡献，包括受邀演讲、海报、参加研讨会分组讨论以及会后前往附近斯普林格维尔的实地考察期间的讨论。特别是早期职业科学家将从三个方面受益：(1) 在会议上，他们将参与有关了解火山领域的前沿科学的讨论和演示，(2) 他们将了解与美国地质调查局同事的合作机会。深入参与会议的组织，并与国际同事一起，（3）他们将了解他们的学科研究如何与火山领域相关的其他科学议程相契合，从而扩大他们自己的研究成果的范围和影响。会议将对美国西部和世界各地分布式火山活动的社区产生直接影响。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。
