GeoPRISMS Synthesis Workshop: Volatiles from Source to Surface

挥发物(如水、二氧化碳、硫、氯、氟)在几乎每一个地球过程中都发挥着重要作用，从我们大气的组成到火山喷发是否会爆炸。对挥发物在地球上的分布和迁移进行量化和跟踪的能力是了解许多过程的基础，但需要勤奋和聪明的方法来测量挥发性物质的浓度。该项目将支持一个关于挥发物的GeoPRISMS合成讲习班。尽管挥发物具有明显的重要性，但在了解它们在地球内的储存、通量、化学相互作用以及在构造板块边界内和周围的过程中的作用方面仍然存在挑战。在过去的十年中，GeoPRISMS计划在了解挥发物方面取得了巨大的进步，但仍需综合这些跨学科的发现。研讨会的目标将是(1)在广泛的研究社区内分享和综合进展；(2)确定悬而未决的问题并与重点工作组一起促进解决方案；(3)将学生与职业生涯早期、中期和晚期的科学家培养和整合到新的研究计划中；以及(4)在多学科社区中建立合作。这次研讨会将收集和分发数据集和教育材料，并制作1分钟的视频，突出过去十年为GeoPRISMS计划做出贡献的不同职业阶段的研究人员。地球过程中挥发物的影响范围从俯冲板块的结构和成分演化、裂谷启动、地幔熔融、岩浆分异、岩浆上升、火山喷发和气体排放。这些过程从根本上控制着地壳、地幔和大气的组成和性质。理解和联系这些过程并跟踪它们在整个地球上的分布和迁移的能力是将观测和过程联系起来的基本要求。跨学科研究项目允许从多个角度和在不同的构造环境中探讨挥发性运输等主题，提供比单一学科研究更多的观察和更可靠的模型。为继续在丰富多样的挥发物领域取得进展，将举办一次讲习班，以分享学科和地理信息系统场地的具体结论和解释，以查明空间和/或科学重叠的区域，界定重点突出和易于处理的问题，并确定有助于解决这些问题的行动项目。然而，跨学科项目成功的基础是对所有涉及的方法及其局限性的基本了解。该研讨会的早期职业生涯部分将帮助那些在跨学科项目中接触较少的即将到来的科学家弥合这一差距。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Volatiles (e.g., water, carbon dioxide, sulfur, chlorine, fluorine) play important roles in nearly every Earth process, from the makeup of our atmosphere to whether a volcanic eruption will be explosive. The ability to quantify and track the distribution and migration of volatiles through the Earth is fundamental to the understanding of numerous processes but requires diligent and clever methods for measuring volatile concentrations. This project will support a GeoPRISMS synthesis workshop on volatiles. Despite the clear significance of volatiles, challenges remain in understanding their storage within Earth, fluxes, chemical interactions, and roles in processes in and around tectonic plate boundaries. In the last decade, the GeoPRISMS program has led to immense progress towards understanding volatiles, but it remains to synthesize these findings across disciplines. The objectives of the workshop will be to (1) share and synthesize progress within the broad research community; (2) identify outstanding questions and foster solutions with focused working groups; (3) develop and integrate students with early-, mid-, and late-career scientists into new research initiatives; and (4) build collaboration in a multidisciplinary community. This workshop will collect and distribute datasets and education materials, as well as create 1-minute videos that highlight researchers in different stages of their careers that have contributed to the GeoPRISMS program in the last decade.The influence of volatiles in Earth processes ranges from the structural and compositional evolution of a subducting slab, rift initiation, mantle melting, magmatic differentiation, magma ascent, and volcanic eruption and gas emission. These processes exert fundamental controls over the composition and properties of Earth’s crust, mantle, and atmosphere. The ability to understand and link these processes and track their distribution and migration throughout Earth is a fundamental requirement for linking observation and process. Interdisciplinary research projects allow for topics such as volatile transport to be approached from multiple perspectives and in varied tectonic settings, providing more observations and more robust models than can be achieved by single-discipline studies. To continue advancement in the rich and diverse field of volatiles, a workshop will be held to share discipline and GeoPRISMs site specific findings and interpretations, which will identify regions of spatial and/or scientific overlap, define focused and tractable questions, and identify action items to help address these questions. Fundamental to the success of interdisciplinary projects, however, is a basic understanding of all of the involved methodologies and their limitations. The early career portion of this workshop will serve to help bridge that gap for upcoming scientists that have had less exposure to interdisciplinary projects.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.
