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

小行星9521470 该方案是一个热液羽流采样方案，将在南纬17度的东太平洋海隆南部进行ALVIN潜水方案。 潜水项目由M.莉莉和K·冯·达姆 这项研究将探讨年轻羽流中活性物质的演变，并将ALVIN取样的各个喷口类别与离开喷口区的综合羽流成分联系起来。 一系列CTD透射仪-玫瑰状拖丝将提供连续的热液示踪段，并将与一系列垂直水铸结合使用，在与ALVIN喷口样品有关的羽流的特定部分集中水样。 将结合真实的时间和船上数据，在测深和辅助测量数据的框架内通过梯度分析确定或核实喷口源。

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.
