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.

挥发物（例如，水，二氧化碳，硫，氯，氟）几乎在地球的每一个过程中都扮演着重要的角色，从我们大气的构成到火山爆发是否会爆炸。量化和跟踪挥发物在地球上的分布和迁移的能力是理解许多过程的基础，但需要勤奋和聪明的方法来测量挥发物浓度。该项目将支持GeoPRISMS挥发物综合研讨会。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及其周围过程中的作用方面仍然存在挑战。在过去的十年中，GeoPRISMS计划在理解挥发物方面取得了巨大的进展，但仍然需要跨学科综合这些发现。该研讨会的目标将是（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）发展和整合学生与早期，中期和后期职业科学家进入新的研究计划;（4）在多学科社区建立合作。本次研讨会将收集和分发数据集和教育材料，以及创建一分钟的视频，突出在过去十年中为GeoPRISMS计划做出贡献的研究人员在其职业生涯的不同阶段。挥发物在地球过程中的影响范围从俯冲板片的结构和成分演变，裂谷起始，地幔熔融，岩浆分异，岩浆上升，火山喷发和气体排放。这些过程对地壳、地幔和大气的组成和性质起着根本性的控制作用。理解和联系这些过程并跟踪其在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不同的构造环境中探讨挥发性输运等主题，提供比单学科研究更多的观测和更强大的模型。为了继续在丰富多样的挥发物领域取得进展，将举办一个研讨会，分享学科和GeoPRISMs现场具体的调查结果和解释，这将确定空间和/或科学重叠的区域，确定重点和易处理的问题，并确定行动项目，以帮助解决这些问题。然而，跨学科项目成功的基础是对所有相关方法及其局限性的基本理解。该研讨会的早期职业部分将有助于弥合那些较少接触跨学科项目的未来科学家的差距。该奖项反映了NSF的法定使命，并被认为值得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来支持。
