Conference: Workshop to catalyze understanding of mantle magma supply at subduction zones & beyond

这笔拨款将支持一个重点多学科研讨会，以促进对地幔源岩浆向火山系统供应的理解。为期3天的研讨会将汇集约50名岩石学家、地震学家、火山学家、野外地球物理学家和地球动力学家，目的是促进跨学科的努力，探索地幔融化过程如何影响跨地壳岩浆系统和地表喷发。一个针对早期职业研究人员的为期半天的研讨会前项目旨在加强下一代科学家的培训和职业发展。地幔岩浆供应是岩浆系统形成的起点，是控制岩浆补给的关键因素，是引发火山喷发的重要因素。然而，从地幔到地壳的熔体和挥发物的供应速率仍然是岩浆系统中最具挑战性的参数之一。本次研讨会旨在促进地球物理学、气体地球化学、地质学和地球动力学建模方面的最新科学进展的综合，为量化地幔岩浆供应提供新的方法。深入了解地幔供应对于诸如俯冲带4D计划（SZ4D）等工作至关重要，这是一项大规模的地球科学社区努力，旨在探索俯冲带危险的潜在过程。研讨会的主要成果将包括新的跨学科科学合作，以量化和模拟地幔岩浆供应，以及在岩浆可成像性背景下对仪器部署和优先排序提出前瞻性建议。更广泛的影响包括：超越传统学科视角，推进对岩浆供应的理解；研讨会前和研讨会时的活动侧重于早期职业研究人员的参与、培训和职业发展。该奖项反映了美国国家科学基金会的法定使命，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 grant will support a focused multidisciplinary workshop to advance understanding of the supply of mantle-derived magma to volcanic systems. The 3-day workshop will bring together ~50 petrologists, seismologists, volcanologists, field geophysicists, and geodynamicists, with the goal of catalyzing cross-disciplinary efforts to explore how mantle melting processes impact transcrustal magmatic systems and surface eruptions. A pre-workshop, half-day program for early career researchers aims to enhance training and career development for the next generation of scientists. Mantle magma supply is the starting point for building magmatic systems and is a key control on the magma recharge that initiates many volcanic eruptions. Yet, the supply rate of melt and volatiles from the mantle to the crust remains one of the most challenging parameters to constrain in magmatic systems. This workshop aims to galvanize synthesis of recent scientific advances in geophysics, gas geochemistry, geology, and geodynamic modeling that provide new methods to quantify mantle magma supply. Intensive work to understand mantle supply is critical to efforts such as the Subduction Zones in 4D initiative (SZ4D), a large-scale community effort in Earth sciences to probe the processes that underlie subduction zone hazards. Key outcomes of the workshop will include new interdisciplinary scientific collaborations to quantify and model mantle magma supply and forward-looking recommendations for instrument deployment and prioritization in the context of magma imageability. Broader impacts include advancing understanding of magma supply beyond traditional disciplinary perspectives; and pre- and syn-workshop activities focused on early career researcher engagement, training, and career development.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.
