Ge 11d. 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. (with Mike Gurnis)


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 J. 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 Mike Gurnis).
