AGU is convening a Chapman Conference in May 2023 to bring together experts studying hydrothermal circulation to provide a better understanding of these processes and their influence both on current and past ocean chemistry. This grant is to provide support to allow students and early career researchers who would usually not be able to attend and/or travel to the conference to participate. This support is important in expanding the diversity of attended and developing and mentoring future research around this important topic.The largest groundwater systems on Earth are under the oceans. The most vigorous systems are driven by heat from magmas under the long ocean ridges, which form new ocean crust; other systems move through older crust and sediment, and other submarine or island volcanic systems. Ocean water moves through these systems and reacts with the crust and sediments, influencing the chemistry of the ocean over time. This process also produces key mineral deposits on the ocean floor. Understanding these systems is important, for example, in considering the role of the ocean for long term storage of captured carbon dioxide and thus addressing climate change. This award is co-funded by the Geobiology and Low-Temperature Geochemistry Program in the Division of Earth Sciences with the Marine Geology and Geophysics and Chemical Oceanography Programs in the Division of Ocean Sciences.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.

Agu将于2023年5月召集一次查普曼会议，以召集研究水热循环的专家，以更好地了解这些过程及其对当前和过去海洋化学的影响。这笔赠款是为了允许通常无法参加和/或前往会议参加的学生和早期职业研究人员参加。这种支持对于扩大参与和发展和指导这一重要主题的未来研究的多样性很重要。地球上最大的地下水系统在海洋之下。最有力的系统是由长长的海脊下的岩浆的热量驱动的，岩浆形成了新的海皮；其他系统穿过旧的外壳和沉积物，以及其他海底或岛屿火山系统。海水通过这些系统移动，并与地壳和沉积物反应，随着时间的推移影响海洋的化学。该过程还在海底产生了关键的矿物质沉积物。 理解这些系统很重要，例如，在考虑海洋在长期存储捕获的二氧化碳并从而解决气候变化方面的作用时。 该奖项由地球科学和低温地球化学计划共同资助了海洋科学和地球物理学和化学海洋学计划的地球科学部，这一奖项反映了NSF的法定任务，并通过基金会的知识优点和广泛的影响来评估NSF的法定任务。
