**Ge 11d/ Ge 102. Introduction to Geophysics**.
9 units (3-0-6);
second term. Prerequisites: Ch 1, Ma 2
a, Ph 2 a. An introduction to the geophysics of the solid earth;
formation of planets; structure and composition of Earth; interactions
between crust, mantle, and core; surface and internal dynamics; mantle
convection; imaging of the interior; seismic tomography. Ge 11d is for
undergrads, and Ge 102 is for graduate students.

**Ge 111 ab. Applied Geophysics Seminar and Field Course**. An introduction
to the theory and application of basic geophysical field techniques
consisting of a comprehensive survey of a particular field area using a
variety of methods (e.g., gravity, magnetic, electrical, GPS, seismic
studies, and satellite remote sensing). The course will consist of a
seminar held in the third term, which will discuss the scientific
background for the chosen field area, along with the theoretical basis
and implementation of the various measurement techniques. The 6–10 day
field/data analysis component is covered in Ge 111 b. May be repeated
for credit with an instructor’s permission.
(with Joann Stock).

a. Applied Geophysics Seminar. 6 units (3-3-0); third term.
Prerequisite: instructor’s permission.

b. Applied Geophysics Field Course. 9 units (0-3-6); summer.
Prerequisite: Ge 111 a.

**Ge 165. Geophysical Data Analysis**. 9 units (3-0-6); first term.
Prerequisites: basic linear algebra and Fourier transforms. Introduction
to modern digital analysis: discrete Fourier transforms, Z-transforms,
filters, deconvolution, auto-regressive models, spectral estimation,
basic statistics, 1-D wavelets, model fitting via singular valued
decomposition.

**Ge 168. Crustal Geophysics**. 9 units (3-0-6); second term. Prerequisite:
ACM 95/100 or equivalent, or instructor’s permission. The analysis of
geophysical data related to crust processes. Topics include reflection
and refraction seismology, tomography, receiver functions, surface
waves, and gravity.

**Ge 211. Applied Geophysics II**. Units to be arranged. Prerequisite:
instructor’s permission. Intensive geophysical field experience in
either marine or continental settings. Marine option will include
participation in a student training cruise, with several weeks aboard a
geophysical research vessel, conducting geophysical measurements
(multibeam bathymetry, gravity, magnetics, and seismics), and processing
and interpreting the data. Supporting lectures and problem sets on the
theoretical basis of the relevant geophysical techniques and the
tectonic background of the survey area will occur before and during the
training cruise. The course might be offered in a similar format in
other isolated situations. The course will be scheduled only when
opportunities arise and this usually means that only six months’ notice
can be given. Auditing not permitted. Class may be taken more than once.
(with Joann Stock).

**Ge 263. Computational Geophysics**. 9 units (3-0-6); second term.
Prerequisite: introductory class in geophysics, class in partial
differential equations, some programming experience. Finite-difference,
pseudospectral, finite-element, and spectral-element methods will be
presented and applied to a number of geophysical problems including heat
flow, deformation, and wave propagation. Students will program simple
versions of methods. (with Jean-Paul Ampuero and Mike Gurnis).
