W.J. Su, R.L. Woodward, A.M. Dziewonski, "Degree-12 model of shear velocity heterogeneity in the mantle," Journal of Geophysical Research -- Solid Earth, 99:6945-80, 1994. (Cited in more than 50 publications as of February 1996) Comments by Adam Dziewonski, Harvard University
Previously, he explains, "all seismological models mapping the movement of materials in the Earth's crust and mantle were represented in one dimension -- namely, along the radius." He adds that such one-dimensional models deviated considerably from actual seismological behavior.
According to Adam Dziewonski, a professor of geophysics at Harvard University, this paper describes the "highest resolution available for three-dimensional, seismological models of the Earth." He relates that such models are important because they help geologists understand the composition and movement of materials below the Earth's crust.

"The single-dimensional models treat the Earth as a...
