magnetotellurics

[mag‚ned·ō·tə′lür·iks]
(geophysics)
A geophysical exploration technique that measures natural electromagnetic fields to image subsurface electrical resistivity, providing information about the earth's interior composition and structure since naturally occurring rocks and minerals exhibit a broad range of electrical resistivities.

The thing that is remarkable about Emily and made her the perfect person to do this study is that, because of her two very disparate scientific interests in experimental petrology and magnetotellurics, she was able to put these different results together and say, "They're telling us the mantle's hotter than we thought.
