This project involves the detailed analysis of coincident seafloor imagery and hydrothermal measurements of the water column that have been collected along a 600 km long section of the superfast spreading southern East Pacific Rise. Previous regional-scale analysis of these data has revealed the large-scale hydrothermal plume patterns and segment-scale volcanic and tectonic controls on hydrothermal venting at these spreading rates. The project will explore the use of various multivariate statistics to characterize the distribution and connections between the many geophysical and hydrothermal measurements, produce maps of the five known hydrothermal vent areas, and provide constraints on the fine-scale segmentation. Additionally, the project involves student interns and the dissemination of fly-by movies, popular teaching tools that will be available to the public.

该项目涉及详细分析沿超快速扩张的南东太平洋海隆沿着600公里长的一段收集的同步海底图像和水柱热液测量数据。 先前对这些数据进行的区域尺度分析揭示了大规模热液羽流模式和分段尺度火山和构造对这些扩张速率下热液喷发的控制。 该项目将探讨如何利用各种多元统计数据来确定许多地球物理和热液测量结果的分布和联系，绘制五个已知热液喷口区的地图，并提供对精细分割的限制。此外，该项目还涉及学生实习和传播飞行电影，这是一种将向公众提供的流行教学工具。
