Relationships between Hydrothermal Plumes and Sampled Vents on a Superfast-Spreading Center: The Southern East Pacific Rise

9521470煤矿这是一个热液羽流采样计划，将在阿尔文潜水计划期间，在南太平洋17度的南太平洋隆起上进行。潜水项目由M.Lilley和K Von Damm领导。这项研究将解决年轻羽流中活性物质的演化问题，并将阿尔文采样的单个喷口类别与离开喷口区域的综合羽流成分联系起来。一系列CTD-透射计-花环拖缆将提供连续的热液示踪剂，并将与一系列垂直水铸相结合，在与阿尔文喷口样品相关的羽流的特定部分集中水样。在水深测量和辅助测量数据的框架内，将结合实时和船上数据，通过梯度分析来定位或验证喷口来源。

9521470 Collier This program is a hydrothermal plume sampling program that will take place during ALVIN dive program on the southern East Pacific Rise at 17 degrees south. The dive program is led by M. Lilley and K Von Damm. The research will address the evolution of reactive species in the young plumes and will tie the individual vent-classes sampled by ALVIN to the integrated plume compositions leaving the vent fields. A series of CTD-transmissometer-rosette tows will provide continuous sections of hydrothermal tracers and will be combined with a series of vertical hydrocasts concentrating water samples at specific portions of the plumes associated with ALVIN vents samples. Real time and shipboard data will be combined to locate or verify the vent sources by gradient analysis within the framework of bathymetric and supporting survey data.
