9419156 Von Damm Hydrothermal system at fast- and superfast-spreading ridges have not been investigated and various trends (geochemical and otherwise) suggest that the variability in hydrothermal systems in slow to moderate rate spreading ridges cannot be extended to superfast ridges. This project involves an ALVIN dive program to study gas and fluid chemistry of hydrothermal systems on the East Pacific Rise 17-21degrees south. The intensity of local hydrothermal activities here are indicated by the He-plume.

小行星9419156 尚未对快速和超快速扩张海脊的热液系统进行研究，各种趋势（地球化学和其他方面）表明，慢速至中速扩张海脊的热液系统的可变性不能扩展到超快速海脊。 该项目涉及ALVIN潜水计划，研究东太平洋隆起以南17- 21度的热液系统的气体和流体化学。 氦柱指示了当地热液活动的强度。
