This project will analyze the geochemistry of sediment porewaters in cores taken from the flank of the East Pacific Rise. Geochemical gradients derived from the cores will be combined with measures of heat flow, physical properties and seismic mapping to e collected by German colleagues, and the data used to (1) calculate vertical velocity of porewater flow; (2) determine the composition of seawater in the underlying basalt; (3) constrain the mechanisms by which seawater flows into basement and (4) provide data to constrain conceptual and numerical models of subsurface circulation.

该项目将分析东太平洋海隆侧翼取芯的沉积物孔隙水的地球化学。 将把从岩芯中得出的地球化学梯度与德国同事收集的热流、物理性质和地震绘图的测量结果结合起来，并将数据用于（1）计算孔隙水流动的垂直速度;（2）确定下面玄武岩中海水的成分;（3）约束海水流入基底的机制;（4）提供数据来约束地下环流的概念和数值模型。
