Benthic Flux Meter Study Across the Costa Rica Margin

正在为部署14个海底通量计提供资金，这些通量计将与海底地震仪（OBSs）结合使用，并在哥斯达黎加俯冲带部署8个自主通量计。仪表将提供有关扩散流体排出模式在这一收敛边界的区域变化的信息。该研究将与哥斯达黎加俯冲系统的另一项资助研究一起进行，该研究将部署海底地震仪。通量计设计用于测量缓慢至中等流速，并将提供广泛的区域覆盖。在哥斯达黎加系统中，大部分流体排出预计将是缓慢到中等扩散流动。了解这些通量率与边际在俯冲工厂（SubFac）和SEIZE主题上的实验目标有关。

Funds are being provided for the deployment of 14 benthic flux meters that will be combined with ocean-bottom seismometers (OBSs), and 8 autonomous flux meters, across the Costa Rica subduction zone. The meters will provide information about the regional changes in diffuse fluid expulsion patterns across this convergent margin. The study will be carried out in conjunction with another funded study across the Costa Rica subduction system that will deploy the OBSs. The flux meters are designed to measure slow to moderate flow rates and will provide broad regional coverage. In the Costa Rica system most of the fluid expulsion is expected to be slow to moderate diffuse flow. Knowing these flux rates is relevant to the objectives of the MARGINS' experiments on the Subduction Factory (SubFac) and SEIZE topics.
