| | The PLUME Cruises |
The interdisciplinary Plume-Lithosphere Undersea Melt Experiment studies the shape and the origin of the mantle plume beneath the Hawaiian hotspot that is responsible for spectacular volcanism on the surface. The centerpiece of this 5-year project is an unprecedented long-term deployment of broad-band OBS (ocean bottom seismometers) to record teleseismic earthquakes. These recordings will let us illuminate the deep interior beneath Hawaii using tomographic techniques much like what is used for CAT scans of the human body. This web page will summarize the ongoing cruises and research results of the project that has started in January 2005 with the first deployment cruise.
