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月召开查普曼会议，汇集研究热液循环的专家，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。这项补助金是提供支持，让学生和早期职业研究人员谁通常不能出席和/或前往会议参加。这种支持对于扩大参加者的多样性以及围绕这一重要主题发展和指导未来的研究非常重要。地球上最大的地下水系统位于海洋之下。最活跃的系统是由长洋脊下的岩浆产生的热量驱动的，这些岩浆形成了新的海洋地壳;其他系统则穿过较老的地壳和沉积物，以及其他海底或岛屿火山系统。海水在这些系统中流动，与地壳和沉积物发生反应，随着时间的推移影响海洋的化学性质。这一过程还在海底产生了重要的矿藏。 例如，在考虑海洋在长期储存捕获的二氧化碳方面的作用，从而应对气候变化方面，了解这些系统是重要的。 该奖项由地球科学部的地球生物学和低温地球化学项目与海洋科学部的海洋地质学、地球物理学和化学海洋学项目共同资助。该奖项反映了NSF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。
