As part of this project the principal investigators will develop an ocean bottom seismometer with a pressure sensor to be used to measure the deformation of the sea bed due to passing trains of sea-surface waves. In order to increase the coupling between the sea bed and the instrument, the PI's propose to design a hydraulic system that will bury the seismometer housing in the sea bed. The instrument will be deployed on the Oregon accretionary prism where it will be used to determine the bold porosity and permeability of the prism. These measurements are of great importance in modeling the deformation of the prism.

作为该项目的一部分，主要研究人员将开发一种带有压力传感器的海底地震仪，用于测量由于海面波浪经过而引起的海床变形。为了增加海床与仪器之间的耦合，PI建议设计一种液压系统，将地震仪外壳埋在海床中。该仪器将被部署在俄勒冈州的增生棱镜上，在那里它将被用来确定棱镜的大胆孔隙度和渗透率。这些测量对于模拟棱镜的变形是非常重要的。
