Hydrothermal Plume Particle Flux and Its Biochemical Implications

目标是（1）定义时间变异性， 悬浮和沉降的热液颗粒通量， 了解通量与区域深海的关系 流程和（2）使用关键组成变量来定义 颗粒去除的机制和速率。 数据来自两个 将使用Juan de Fuca海岭奋进段的系泊设备。 来自其中一个系泊设备的数据将延长数据的时间序列 从早期的系泊中获得;另一个系泊将提供 数据来自更靠近喷口的区域。 %%% 海底热液系统的一个组成部分是 羽流排放到深海。 人们很少了解 这个过程的细节。 这件事的首席调查员 该项目是该领域的领导者之一， 这个项目是他开创性工作的延伸。

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.
