项目摘要

Our program will explore the interactive physical-chemical processes at play in gradient driven submarine environments by focusing on three key questions within a hydrothermal system on the Endeavour Segment of the Juan de Fuca Ridge. These questions include: 1) What are the physical and chemical consequences of phase separation in black smokers; 2) What is the origin of low-temperature diffusely venting fluids that are associated with high-temperature fields, but which also occur far-field, and 3) How can tidal perturbations be used to explore subsurface chemical and microbiological processes within a single hydrothermal field. Investigation of these questions is important in that phase separation (e.g. boiling), diffuse venting, and tidal forcing operate in many, if not all, ridge crest hydrothermal environments; all of these processes are accessible for direct study in the four hydrothermal fields on the Endeavour. Using a range of in situ physical and chemical sensors and a new strategy for sustained fluid sampling, we will document the effects of tidal perturbations in fluid temperature, pressure, composition, and flow rate in areas of both high- and low-temperature flow. Our goal is to develop a series of interdisciplinary models linking the processes that produce these changes. In addition, observed tidal effects will provide insights into the responses of the entire system to identifiable perturbations and may allow us to develop models of subseafloor flow patterns and permeability structure.
我们的计划将通过关注Juan de Fuca Ridge的努力领域的水热系统中的三个关键问题,探索在梯度驱动的潜艇环境中发挥作用的交互式物理化学过程。 这些问题包括:1)黑人吸烟者的相位分离的物理和化学后果是什么; 2)与高温场相关的低温扩散流体的起源是什么,但也发生了远场,3)如何使用潮汐扰动来探索单个水热场中的地下化学和微生物过程。 对这些问题的研究在该相分离(例如沸腾),弥漫性排气和潮汐强迫在许多(如果不是全部)(如果不是全部)的潮汐水热环境中都很重要。所有这些过程均可在努力的四个水热场中进行直接研究。使用一系列原位物理和化学传感器以及持续流体采样的新策略,我们将记录潮汐扰动在流体温度,压力,组成和流量中对高温和低温流的区域的影响。 我们的目标是开发一系列连接产生这些变化的过程的跨学科模型。 此外,观察到的潮汐效应将为整个系统对可识别的扰动的响应提供见解,并可能使我们能够开发子层状流量模式和渗透率结构的模型。
