This is a project to initiate a field program to determine the pattern of strain accumulation across the Juan de Fuca ridge by establishing and repeatedly resurveying a network of benchmarks in the vicinity of the ridge crest. the system involves interrogation of precision acooustic transponders from a near.bottom towed survey vehicle and use of the resulting range measurements to determine the internal geometry of the array.

该项目旨在启动一项实地计划，通过在山脊顶部附近建立并反复重新测量基准网络来确定胡安·德富卡山脊上的应变积累模式。该系统涉及从近底拖曳测量车询问精密声学应答器，并使用所得的距离测量结果来确定阵列的内部几何形状。
