Revealing the plume beneath Hawaii
1. The Hawaiian Island chain was formed by a plume of hot, buoyant rocks from the mantle, but scientists know little about it.
2. To determine the plume’s depth, width, and temperature for the first time, scientists plan to deploy 35 ocean-bottom seismographs.
3. The OBSs will record earthquake-generated seismic waves traveling through the plume, revealing new insights on how mantle plumes work. (Jayne Doucette. )[back]
