Hydrothermal and Structural Investigations along the fastestSpreading Center: The 28'- 32'S EPR Reorganizing Plate Boundary

嘿，这个项目将收集高分辨率的深拖曳侧面扫描和水深数据，以绘制断层、裂缝和东太平洋隆起南纬30度部分地区近期火山喷发地点的详细模式。安装在运载工具上的CTD/浊度计将提供精确的热液羽流分布，两向测量将确定温度、颗粒浓度和某些化学物质溶解分数的二维异常。本项目的目的是了解超快速扩张速率下热液喷口的构造控制、喷口的时间控制以及热液喷口与深海洋流在远场羽流形成中的相对重要性。

9529737 Hey This project will collect high-resolution deep-towed sidescan and bathymetric data to map the detailed pattern of faults, fissures, and recent volcanic eruptive sites along a section of the East Pacific Rise at 30 degrees south. CTD/nephelometer mounted on the vehicle will provide precise hydrothermal plume distributions, and tow-yo surveys will determine two-dimensional anomalies of temperature, particle concentration and the dissolved fraction of certain chemical species. The objective of this project is to understand the structural controls on hydrothermal venting at superfast spreading rates, the temporal controls on venting, and the relative importance of hydrothermal venting and deep ocean currents in forming far-field plumes.
