Objectives are to (1) define temporal variability in suspended and settling hydrothermal particle fluxes and understand the relationship of the fluxes to regional deep sea flow and (2) to use key compositional variables to define mechanisms and rates of particle removal. The data from two moorings in Endeavor segment of Juan de Fuca Ridge will be used. Data from one of the moorings will extend the time series of data obtained from earlier moorings; the other mooring will provide data from closer to the vent field than earlier moorings. %%% One component of the seafloor hydrothermal system is the plume discharge into the deep ocean. Little is understood about the details of this process. The principal investigator on this project is one of the leaders in the field on this subject and this project is an extension of his pioneering work.

目标是(1)确定悬浮和沉淀热液颗粒通量的时间变异性，并了解通量与区域深海流动的关系，以及(2)使用关键组成变量来确定颗粒去除的机制和速率。将使用Juan de Fuca Ridge奋进地段的两个系泊数据。其中一个系泊的数据将扩展从较早的系泊获得的数据的时间序列；另一个系泊将提供来自比较早的系泊更接近喷气场的数据。%海底热液系统的一个组成部分是向深海排放的羽流。关于这一过程的细节，人们知之甚少。该项目的首席研究员是该领域这一主题的领导者之一，该项目是他开创性工作的延伸。
