General course objective is to provide students
with an introduction to the methods and theory of geophysics used
in earth exploration and prospecting.
* Seismology: seismic waves. Physics of waves, stress and strain,
reflection and refraction, Snell's Law, application of Snell's Law
to seismic exploration, ray parameter, seismic refraction modeling,
ray tracing. Seismic reflection methods and processing. Stacking,
velocities, migration. Use of seismic processing software Seismology
in the deep earth. Current knowledge of the interior based on seismology
from the surface to the inner core. Tomography.
* Potential field methods. Concept of the potential. Gravity and
the geoid. Gravity methods. Bouguer and Free Air anomalies, isostacy.
Magnetic methods. Magnetic fields and magnetic anomalies. Relationship
to gravity. Magnetic methods concluded. Other methods- electrical,
resistivity. Well logging.
* Methods in marine surveying. Bathymetric sounding, ocean instrumentation,
reflection and refraction at sea, swath mapping.
