AGU Chapman Conference on Distributed Volcanism; Flagstaff, AZ; March 2020

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调查人员参加美国地球物理联盟（AGU）查普曼会议，该会议将于2020年3月16日至20日在亚利桑那州弗拉格斯塔夫举行，讨论，开发和测试分布式火山活动的概念模型。科学界的关注现在尤其重要，因为在监测稀少的火山地区，城市、社区和关键基础设施不断发展。大多数地下火山都分布在由数十至数百个喷口组成的广泛分布的火山区，这些喷口包括从火山渣锥到火山口的各种喷发方式和地貌，并且位于各种构造环境中。会议将提供所需的背景，并集中在分布式，单成因火山作用的问题，总结目前的研究方向。在美国西部，分布广泛的火山区实际上没有受到监测。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式火山区上。在了解这些火山区岩浆的起源、它们在岩石圈中的大规模迁移以及它们喷发的统计模型方面已经取得了很大的进步。然而，关于这种最常见的火山作用方式，仍然存在非常基本的问题。该会议的结构是提供网络活动和相关的讨论，以及介绍早期的职业参与者在美国西部的一些最迷人的火山领域这个AGU查普曼分布式火山会议的结构，以鼓励跨学科的接触和思考，在不同的领域，如地球化学，地球物理学和火山科学。要解决的主题是地球物理监测技术和模型（例如，强大的地震和变形监测）将在火山区发挥作用。此外，有趣的是，会议将涉及科学家如何在小体积系统中耦合岩浆上升的地球化学和地球物理模型。目前，对于如何适当应对火山区的动荡和相关危害，以及这些与弧复合火山有何不同，社区尚未达成共识。预计这次会议将对早期的职业科学家有很大的好处。预计他们将为会议的所有阶段作出重大贡献，包括应邀发表演讲、张贴海报、参加讲习班分组会议以及会后到附近的Springerville火山区实地考察期间的讨论。特别是早期的职业科学家将在三个方面受益：（1）在会议上，他们将参加关于了解火山场的尖端科学的讨论和演讲，（2）他们将了解与美国地质勘探局同事的合作机会，他们深入参与了会议的组织工作，并与国际同事，（3）他们将了解他们的学科研究如何与其他与火山领域有关的科学议程相适应，扩大他们自己的调查范围和影响。会议的讨论和成果将对美国西部和世界各地生活在分布式火山活动中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知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
