GEOPHYS 201: Frontiers of Geophysical Research at Stanford: Faculty Lectures

Required for new students entering the department. Second-year and other graduate students may attend either for credit or as auditors. Department faculty and senior research staff introduce the frontiers of research problems and methods being employed or developed in the department and unique to department faculty and students: what the current research is, why the research is important, what methodologies and technologies are being used, and what the potential impact of the results might be. Offered every year, autumn quarter.
Terms: Aut | Units: 1
Instructors: Zebker, H. (PI)

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

GEOPHYS 205: Effective Scientific Presentation and Public Speaking

The ability to present your work in a compelling, concise, and engaging manner will enhance your professional career. This course breaks down presentations into their key elements: the opening, body of the talk, closing, slide and poster graphics, Q&A, pacing, pauses, and voice modulation. We use clips from archived talks, slide sets and posters to illustrate the good, the bad, and the ugly. Each participant will use their upcoming conference talk or poster (e.g., AGU, SEG), or upcoming job talk or funding pitch, as their class project. The course will be 40% group meetings and 60% individual coaching. Everyone will come away a more skilled and confident speaker than they were before. Instructor: Ross S. Stein (USGS) nThe course syllabus is the third publication in http://profile.usgs.gov/rstein
Terms: Aut | Units: 2
Instructors: Stein, R. (PI)

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

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/.

GEOPHYS 218: Understanding Natural Hazards, Quantifying Risk, Increasing Resilience in Highly Urbanized Regions (EESS 118, EESS 218, GEOPHYS 118, GES 118, GES 218)

Integrating the science of natural hazards, methods for quantitatively estimating the risks that these hazards pose to populations and property, engineering solutions that might best ameliorate these risks and increase resilience to future events, and policy and economic decision-making studies that may increase long-term resilience to future events. Panel discussions by outside experts exploring the science, engineering, policy, and economics that underly the hazards, risks, and strategies for increasing resilience. Group assignments to evaluate the way in which natural hazards, and human population and developing interact in megacities to produce risk, and what strategies might be adopted in each area to reduce risks posted by the specific hazards faced by these urban areas.
Last offered: Winter 2014

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

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