Sentences with phrase «slowest wave velocity»

Inspired by a 2012 paper that proposed a correlation between such hotspots and the velocity of seismic waves moving through Earth's interior, UC Santa Barbara geochemist Matthew Jackson teamed with the authors of the original paper — Thorsten Becker of the University of Texas at Austin and Jasper Konter of the University of Hawaii — to show that only the hottest hotspots with the slowest wave velocity draw from the primitive reservoir formed early in the planet's history.

Not exact matches

The relatively small rock bodies are termed «ultra-low velocity zones» because seismic waves greatly slow down as they pass through them.

Led by Carnegie's Ho - kwang «Dave» Mao, the research team believes that as much as 300 million tons of water could be carried down into Earth's interior every year and generate deep, massive reservoirs of iron dioxide, which could be the source of the ultralow velocity zones that slow down seismic waves at the core - mantle boundary.

These seismic measurements enabled scientists to visualize these ultralow velocity zones in some regions along the core - mantle boundary, by observing the slowing down of seismic waves passing through them.

Led by Geophysical Laboratory's Ho - kwang «Dave» Mao, the research team believes that as much as 300 million tons of water could be carried down into Earth's interior every year and generate deep, massive reservoirs of iron dioxide, which could be the source of the ultralow velocity zones that slow down seismic waves at the core - mantle boundary.
