State of the Arc Conference (SOTA) 2010: Subduction to Eruption

学术价值：第五届Arc状态(SOTA)会议将于2010年9月19日至25日在希腊锡罗斯和圣托里尼举行。其主题将是“俯冲到喷发”，分主题将包括：(1)俯冲物质内的递进变质反应；(2)对弧形岩浆活动的地球物理和地球动力学制约；(3)在地幔和地壳层面对弧形岩浆热和物质平衡的观测和实验制约；(4)岩浆脱气和分异的时间尺度；以及(5)火山灾害。这次会议将汇集约75名国际研究人员和学生，他们的工作与这些主题有关。这项提案寻求美国国家科学基金会的资助，以支付约10名研究生或博士后和约10名特邀演讲者的注册费。经验表明，戈登会议式的形式使SOTA会议能够解决关键问题，并促进与会者之间的新研究方向。将邀请大约11名主旨演讲者和煽动者，他们的任务将是总结与上述分主题有关的过去和前沿研究。其他与会者将主要以海报形式介绍相关研究成果。会议的大部分时间将围绕地球动力学过程、岩浆分异和火山灾害之间的关系展开广泛和集中的讨论。挑衅者将被邀请来刺激这些讨论。赛洛斯和圣托里尼的实地考察将看到俯冲物质和弧火山活动的重要方面。组委会将召集会议，并负责邀请主题演讲者和吸引其他与会者，指导会议的科学内容，并准备书面摘要供发表。广泛的影响：国家科学基金会约一半的资金将用于支付年轻研究人员的注册费。这将确保下一代研究人员在其职业生涯的早期阶段就参与国际科学合作并看到其好处。它还将为这些年轻的研究人员提供与国际公认的专家互动的机会。会议规模较小，不同背景的研究人员(地质学家、岩石学家、地球化学家和地球物理学家)的参与将促进不同群体之间的对话，这对于确定需要解决的重要问题和建立可行的国际伙伴关系来解决这些问题至关重要。灾害将在这次SOTA会议上发挥比以前的会议更核心的作用，预计在开发利用岩石学、地球化学和地球物理信息预测火山灾害轨迹的工具方面将取得进展。

Intellectual Merit: The fifth State of the Arc (SOTA) conference will be convened September 19-25, 2010 at Syros and Santorini, Greece. Its theme will be ?Subduction to Eruption?, and sub-themes will include: (1) prograde metamorphic reaction within subducted materials; (2) geophysical and geodynamic constraints on arc magmatism; (3) observational and experimental constraints on heat and mass balance in arc magmas at mantle and crust levels; (4) time-scales of degassing and differentiation of magmas; and (5) volcanic hazards. This conference will bring together ~75 international researchers and students whose work bears on these themes. This proposal seeks funding from NSF for the registration fee for about ten graduate students or postdocs and about ten invited speakers. Experience has shown that a ?Gordon Conference?-style format allows SOTA meetings to address critical questions and facilitate new research directions amongst participants. Approximately 11 keynote speakers and provocateurs will be invited whose tasks will be to summarize past and cutting edge research bearing on the aforementioned sub-themes. Other participants will present relevant research results, primarily in poster format. The majority of the time of the conference will revolve around extended and focused discussion of the relation between geodynamic processes, magma differentiation, and volcano hazards. The provocateurs will be invited to stimulate these discussions. Field trips on Syros and Santorini will view important aspects of subducted materials and arc volcanism. The organizing committee will convene the meeting and will be responsible for inviting keynote speakers and attracting other participants, guiding the scientific content of the meeting, and preparing a written summary for publication.Broader Impacts: About half the funds from the NSF will be used to pay the registration fee for young researchers. This will ensure that the next generation of researchers will participate in and see the benefit of international scientific cooperation at an early stage in their careers. It also will provide the opportunity of these young researchers to interact with internationally recognized experts. The small size of the meeting and the involvement of researchers with diverse backgrounds (geologists, petrologists, geochemists, and geophysicists) will foment dialogue between different groups, which is critical to identifying important issues to address and viable, international partnerships to address them. Hazards will play a more central role in this SOTA meeting than earlier ones, and it is expected that progress will be made in developing tools to predict hazards trajectories for volcanoes utilizing petrological, geochemical, and geophysical information.
