The P.I. collected a large amount of physical and chemical data during October-December, 1987 in the eastern South Pacific in order to study the hydrothermal plume emanating from the East Pacific Rise, and its effects on the abyssal circulation in the deep south Pacific basin. Shipboard data were collected and deep- water floats were deployed, which are still due to surface, subsequently transmitting data via ARGOS. Data show a strong, highly structured thermal plume, which may allow estimates of vertical (cross-isopycnal) mixing rates on a large scale. In this project, the data will be analyzed in collaboration with a graduate student and other co-workers, and the results submitted for publication.

P.I.为研究东太平洋海隆产生的热液羽流及其对南太平洋深海盆地深海环流的影响，于1987年10月至12月在南太平洋东部收集了大量的物理和化学数据。 收集了船上数据并部署了深水浮标，这些浮标仍然位于水面，随后通过 ARGOS 传输数据。 数据显示出强烈的、高度结构化的热羽流，这可以允许大规模地估计垂直（跨等密度）混合率。 在这个项目中，将与研究生和其他同事合作分析数据，并将结果提交出版。
