Conference: AGU Chapman Conference on Hydrothermal Circulation and Seawater Chemistry

AGU将于2023年5月召开查普曼会议，将研究热液循环的专家聚集在一起，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。这笔赠款是为了提供支持，让通常不能参加和/或不能参加会议的学生和早期职业研究人员参加会议。这种支持对于扩大参加和发展这一重要主题的多样性和指导未来的研究非常重要。地球上最大的地下水系统在海洋之下。最具活力的系统是由长长的洋脊下的岩浆热驱动的，形成了新的洋壳；其他系统通过较老的地壳和沉积物以及其他海底或岛屿火山系统移动。海水通过这些系统运动，并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成分。这一过程还在海底产生了关键的矿藏。例如，了解这些系统对于考虑海洋在长期储存捕获的二氧化碳方面的作用，从而应对气候变化非常重要。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、地球物理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。

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.
