Geophysics and Tectonics |
Global earth science problems are as
diverse as the techniques we use to tackle them. Geophysics and
Tectonic studies combine field-based data acquisition and simplification
of earth processes through understanding physical principles, and
comprehensive mathematical and experimental methods.
