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 overr 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个宽带海底地震仪和10个便携式宽带地震岛站。其目标是：对夏威夷热点下的地幔柱管道进行定位和成像，在足够大的面积上对夏威夷膨胀的根源进行成像，并以足够的分辨率区分地幔柱-岩石圈相互作用的竞争假设，并将地震成像实验的结果与地幔柱的地球动力学和地球化学模型联系起来。
