This is a field and laboratory study of off-axis flow-line sampling to test for petrologic temporal variability. To avoid the petrologic complications that exist near large EPR offsets the study will be sample the EPR at 13 degrees 13-17 minutes north. Two paired and symmertical flow-line sampling transects, separated by 7 km, will be occupied. The goal is to determine whether the composition of the ocean crust varies episodically, quasi-periodically, or not at all.

这是一个离轴的现场和实验室研究 流线取样以测试岩石学时间变化。 为了避免大EPR附近存在的岩石学复杂性， 偏移研究将在13度13-17的EPR采样 分钟北。两对对称流线采样 将占用间隔7公里的样带。目标是 确定海洋地壳的组成是否 间歇性地、准周期性地或根本不发生。
