This project will make coupled chemical and temperature measurements in about 20 high temperature vent sites on the East Pacific Rise, 9-10 degrees north, six diffuse flow vents, and the vents at 21 degrees north on the East Pacific Rise. The questions to be addressed include: What controls the composition of vent fluids exiting from a single vent fore time? Do changes in fluid compositions and temperatures correlate with changes in the associated animal communities? What is the relationship between adjacent diffuse and focused hydrothermal fluids? What is the flux of chemical species from hydrothermal vents to the ocean?

该项目将在北纬9-10度的东太平洋海隆约20个高温喷口、6个扩散流喷口和北纬21度的东太平洋海隆喷口进行化学和温度测量。 要解决的问题包括：是什么控制了从一个单一的喷口喷出的流体组成的时间？ 流体成分和温度的变化是否与相关动物群落的变化相关？ 相邻的扩散热液和聚集热液之间的关系是什么？ 从热液喷口流入海洋的化学物质的流量是多少？
