This project will deploy 64 wide-band ocean-bottom seismometers and ten portable broad-band seismic island stations in a 15-month-long investigation. The objectives are to: locate and image the plume conduit beneath the Hawaiian hotspot, image the roots of the Hawaiian swell over a sufficient area and with a sufficient resolution to distinguish among competing hypotheses for plume-lithosphere interaction, and relate the findings from the seismic imaging experiments to geodynamical and geochemical, models for mantle plumes.

该项目将在为期15个月的调查中部署64台宽带海底地震仪和10个便携式宽带地震岛台站。目标是：对夏威夷热点下方的羽流管道进行定位和成像，对足够区域内夏威夷隆起的根部进行成像，并以足够的分辨率区分羽流-岩石圈相互作用的相互竞争的假设，并将地震发现结果联系起来地球动力学和地球化学成像实验，地幔柱模型。
