This project will continue the time series study of the vent fluids at the hydrothermal site located a 21 degrees north on the East Pacific Rise. Since this hydrothermal site was discovery in 1979 three expeditions to this location have established that the exit temperatures and distinct interfield differences in fluid composition have remained constant with time at the four vent fields. This project will allow the principal investigator to document any changes in chemistry and temperature at each site and will extend the study of this hydrothermal system to over a decade. The results will improve understanding of the evolution of seafloor hydrothermal systems and will further constrain the processes that control the hydrothermal fluxes of elements into the oceans.

本项目将继续进行喷口的时间序列研究 热液区的流体位于北纬21度， 东太平洋隆起 由于这个热液遗址是在1999年发现的， 1979年，三次对该地点的考察已经确定， 出口温度和流体中明显的场间差异 在四个通风口处， 领域的 该项目将允许主要研究者 记录每个地点的化学和温度变化 并将对这一热液系统的研究扩展到 十年 研究结果将有助于加深对进化的理解 海底热液系统，并将进一步限制 控制元素进入热液通量的过程 海洋
