The Texas Advanced Computing Center recently published an article about how science gateways are making it possible for researchers to explore the existence of mantle plumes. Thus far, the plumes are hypothesized, mushroom-shaped upwellings of hot rock from deep in the Earth. With the help of supercomputer simulations, one team has, for the first time, detailed how plumes decelerate seismic waves and how plumes appear in seismic tomographic images of the Earth's mantle. This work could help...
