Theres a giant crystal buried deep within the Earth, at the very center, more than 3,0. It may sound like the latest fantasy adventure game or a new Indiana Jones movie, but it happens to be what scientists discovered in 1. Earths inner core. This remarkable finding, which offers plausible solutions to some perplexing geophysical puzzles, is transforming what Earth scientists think about the most remote part of our planet. To understand whats deep in the Earth is a great challenge, says geophysicist Lars Stixrude. Drill holes go down only 1. Earths radius. Most of the planet is totally inaccessible to direct observation. What scientists have pieced together comes primarily from seismic data. When shock waves from earthquakes ripple through the planet, they are detected by sensitive instruments at many locations on the surface. The record of these vibrations reveals variations in their path and speed to scientists who can then draw inferences about the planets inner structure. This work has added much knowledge over the last ten years, including a puzzling observation Seismic waves travel faster north south than east west, about four seconds faster pole to pole than through the equator. This finding, confirmed only within the past two years, quickly led to the conclusion that Earths solid iron inner core is anisotropic it has a directional quality, a texture similar to the grain in wood, that allows sound waves to go faster when they travel in a certain direction. What, exactly, is the nature of this inner core texture To this question, the seismic data responds with sphinx like silence. The problem, says Ronald Cohen of the Carnegie Institution of Washington, is then were stymied. We know theres some kind of structure, the data tells us that, but we dont know what it is. If we knew the sound velocities in iron at the pressure and temperature of the inner core, we could get somewhere. To remedy this lack of information, Stixrude and Cohen turned to the CRAY C9.
