该项目是对中间扩展的Juan de Fuca海岭进行的综合多道地震调查。 主要目标是：（1）确定沿着洋脊的地壳岩浆体的位置、大小和物理性质，并将这些性质与洋脊最近的喷发历史联系起来;（2）测量岩浆状态指标的速度和厚度变化;（3）根据沉积历史、地壳年龄和基底起伏来描述上地壳的蚀变历史。
英文摘要
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.
