GEODYNAMICS- SIO 234
http://topex.ucsd.edu/geodynamics
A
general course on the dynamics and kinematics of the
solidearth based on the text of Turcotte and Schubert and
Advanced Geodynamics
Prerequisite: some familiarity with
(or willingness to learn ) partial differential equations and
Fourier transforms.
