Seismological detection of a mantle plume?

A detailed seismological study of the mantle beneath the Bowie hotspot, west of Canada, reveals a zone of low seismic velocities. The anomaly, probed at a depth of ∼700 km, adds a delay of 0.15 s to the travel times of seismic waves traversing a region ∼150 km in diameter, located ∼150 km away from...
