REU: Hydrothermal Circulation in a Sedimented Ridge Flank Environment

该项目的目标是了解大洋中脊年轻沉积侧翼的热液循环。该计划包括使用不同的渗透率值和结构对环流进行二维稳态数值模拟，试图对1988年从胡安德富卡山脊收集的数据进行模拟，并在1990年参加加拿大巡航，以获得附近极低基底起伏区域的更多热流和孔压数据。然后，新的数据将被整合到数值模型中。水热循环是决定洋壳热量和化学通量的主要因素。基底起伏对环流格局的影响还不是很清楚，这个模拟和实地考察该地区热量和化学输送的综合方案将有助于澄清这种关系。主要调查人员已经参与了这一领域的初步研究，这是他们工作的合乎逻辑的延伸。

The objective of this project is to understand hydrothermal circulation at young sedimented flanks of mid-ocean ridges. The program involves numerical 2-d steady state modeling of circulation using different permeability values and structures to attempt to model data collected from the Juan de Fuca Ridge in 1988, and participation in Canadian cruise in 1990 to get more heat flow and pore pressure data in an nearby area of remarkably low basement relief. The new data will then be integrated into numerical models. %%% Hydrothermal circulation is a major factor in determining the heat and chemical fluxes through the oceanic crust. The effect of basement relief on the circulation patterns is not well known and this integrated program of modeling and field investigation of the heat and chemical transport in this area will help clarify this relationship. The principal investigators have already been involved in a preliminary study in this area, and this is a logical extension of their work.
