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

9529737嘿，这个项目将收集高分辨率的深拖曳侧扫和水深数据，以绘制沿南30度东太平洋隆起部分的断层、裂缝和最近火山喷发地点的详细模式。安装在飞行器上的CTD/浊度计将提供精确的热液羽流分布，两次测量将确定温度、颗粒浓度和某些化学物质的溶解分数的二维异常。该项目的目的是了解超快扩散速率的热液喷发的构造控制、喷发的时间控制以及热液喷发和深海洋流在形成远场羽流方面的相对重要性。

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.
