US - Iceland Cooperative Research: Study of Hydrothermal Systems

在这个项目中，迈阿密大学罗森斯蒂尔海洋和大气科学学院的研究人员将与冰岛北欧火山研究所的同事合作，利用国际和平研究所为大洋中脊海底热液系统开发的同位素工具，调查在冰岛热液系统中循环的流体的地壳停留时间。这将使这些技术得以改进，用于进一步的海底研究，并使研究人员有机会开发新的同位素技术，最终用于海底系统。此外，还将在井水中部署一个现场伽马探测器，以对氡气进行远程、详细的时间序列测量。冰岛调查人员之前的工作表明，测氡作为地震预报工具的潜力很大。

ABSTRACTOCE-0220303In this project, researchers at the Rosenstiel School of Marine and Atmospheric Sciences at the University of Miami will collaborate with colleagues at the Nordic Volcanic Institute in Iceland to investigate the crustal residence time of fluids circulating through hydrothermal systems of Iceland, utilizing isotopic tools developed by the PI for submarine hydrothermal systems in mid-ocean ridges. This will allow the refinement of these techniques for further seafloor studies, as well as afford the researchers an opportunity to develop new isotopic techniques for ultimate use in submarine systems. Additionally an in-situ gamma detector will be deployed within well waters to make remote, detailed, time-series measurements of radon gas. Previous work by Icelandic investigators has shown that radon measurements have great potential as an earthquake prediction tool.
