9529707 Phipps Moran This project is a pilot teleseismic surface wave study with the goal of mapping the source of the Hawaiian swell. During a 9- month deployment an array of eight ocean-bottom seismometers will collect Rayleigh wave dispersion data from circum-Pacific plate bourdary earthquakes. A 3-D interpretation of these data will give constraints on the lithosphere and upper asthenosphere shear- velocity structure beneath the Hawaiian swell. If this pilot experiment is successful a larger experiment would be proposed to determine which of the three hypotheses for the formation of the swell is correct.

这个项目是一个试验性的远震表面波研究，目的是绘制夏威夷涌浪的来源。在为期9个月的部署期间，一个由8个海底地震仪组成的阵列将收集环太平洋板块边界地震的瑞利波频散数据。对这些数据的三维解释将对夏威夷隆起下的岩石圈和上层软流层剪切速度结构提供约束。如果这个初步实验成功，将提出一个更大的实验，以确定关于膨胀形成的三个假设中哪一个是正确的。
