This project is an integrated multichannel seismic investigation of the intermediate-spreading Juan de Fuca Ridge. The primary goals are: (1) to determine the location, size and physical properties of crustal magma bodies along the ridge and relate these properties to the recent eruptive history of the ridge, (2) to measure the variation invelocity and thickness of the indicators of magmatic state, and (3) to characterize the alteration history of the upper crust as a function of sedimentation history, crustal age and basement relief.

该项目是对中扩散胡安德富卡海岭的综合多道地震调查。 主要目标是：（1）确定沿着山脊的地壳岩浆体的位置、大小和物理性质，并将这些性质与山脊最近的喷发历史联系起来，（2）测量指标的变化速度和厚度岩浆状态，以及（3）将上地壳的蚀变历史描述为沉积历史、地壳年龄和基底起伏的函数。
