Terms: Aut, Win, Spr, Sum | Units: 3-5 | Grading: Letter or Credit/No Credit

GEOPHYS 198: Honors Program

Experimental, observational, or theoretical honors project and thesis in geophysics under supervision of a faculty member. Students who elect to do an honors thesis should begin planning it no later than Winter Quarter of the junior year. Prerequisites: department approval. Seniors defend the results of their research at a public oral presentation.
Terms: Aut, Win, Spr, Sum | Units: 1-3 | Repeatable for credit | Grading: Letter or Credit/No Credit

GEOPHYS 202: Reservoir Geomechanics

Basic principles of rock mechanics and the state of stress and pore pressure in sedimentary basins related to exploitation of hydrocarbon and geothermal reservoirs. Mechanisms of hydrocarbon migration, exploitation of fractured reservoirs, reservoir compaction and subsidence, hydraulic fracturing, utilization of directional and horizontal drilling to optimize well stability. Course will have an online component in 2014-2015. Given alternate years.
Terms: Spr | Units: 3 | Grading: Letter (ABCD/NP)

GEOPHYS 210: Basic Earth Imaging

Echo seismogram recording geometry, head waves, moveout, velocity estimation, making images of complex shaped reflectors, migration by Fourier and integral methods. Anti-aliasing. Dip moveout. Computer labs. See http://sep.stanford.edu/sep/prof/. Offered every year, autumn quarter.
Terms: Aut | Units: 2-3 | Grading: Letter or Credit/No Credit

GEOPHYS 211: Environmental Soundings Image Estimation (GEOPHYS 187)

Imaging principles exemplified by means of imaging geophysical data of various uncomplicated types (bathymetry, altimetry, velocity, reflectivity). Adjoints, back projection, conjugate-gradient inversion, preconditioning, multidimensional autoregression and spectral factorization, the helical coordinate, and object-based programming. Common recurring issues such as limited aperture, missing data, signal/noise segregation, and nonstationary spectra. See http://sep.stanford.edu/sep/prof/.
Terms: Win | Units: 3 | Grading: Letter or Credit/No Credit

GEOPHYS 220: Ice, Water, Fire (GEOPHYS 120)

Introductory application of continuum mechanics to ice sheets and glaciers, water waves and tsunamis, and volcanoes. Emphasis on physical processes and mathematical description using balance of mass and momentum, combined with constitutive equations for fluids and solids. Designed for undergraduates with no prior geophysics background; also appropriate for beginning graduate students. Prerequisites: CME 100 or MATH 52 and PHYSICS 41 (or equivalent). Offered every year, winter quarter.
Terms: Win | Units: 3-5 | Grading: Letter or Credit/No Credit

GEOPHYS 223: Reflection Seismology Interpretation (GEOPHYS 183, GES 223)

The structural and stratigraphic interpretation of seismic reflection data, emphasizing hydrocarbon traps in two and three dimensions on industry data, including workstation-based interpretation. Lectures only, 1 unit. Prerequisite: 222, or consent of instructor.
Terms: alternate years, given next year | Units: 1-4 | Grading: Satisfactory/No Credit

GEOPHYS 229: Earthquake Rupture Dynamics

Physics of earthquakes, including nucleation, propagation, and arrest; slip-weakening and rate-and-state friction laws; thermal pressurization and dynamic weakening mechanisms; off-fault plasticity; dynamic fracture mechanics; earthquake energy balance. Problem sets involve numerical simulations on CEES cluster. Prerequisites: GEOPHYS 287. Offered occasionally.
Terms: Aut | Units: 3 | Grading: Letter or Credit/No Credit


Basic topics and approaches (theory and numerical simulations) on acoustic, electromagnetic, and elastic waves and fields for geophysical applications: dispersion, phase and group velocities, attenuation, reflection and transmission at planar interfaces, high frequency and low frequency approximations, heterogeneous media. Prerequisites: UG level class on waves or consent of instructor.
Terms: Spr | Units: 3 | Grading: Letter (ABCD/NP)
