GEOPHYS 211: Environmental Soundings Image Estimation

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 212: Topics in Climate Change

This introductory classroom course presents Earth's climate system and explores the science and politics of global climate change. Students will learn how the climate system works, the factors that cause climate to change across different time scales, the use of models and observations to make predictions about future climate. The course will discuss possible consequences of climate change in the Earth, and it will explore the evidence for changes due to global warming. There are no prerequisites.

GEOPHYS 213: Quantitative Analysis of Geopressure for Geoscientists and Engineers

In these lectures we will have a dialogue that addresses how to predict, detect and quantify subsurface fluid pressure regimes (geopressure) with more emphasis on fundamental than empiricism that is so common in this field. Rock physics and basin history modeling are important tools to develop an earth model. So is the seismic. Rock physics guided velocity and amplitude modeling tools such as velocity analysis, reflection tomography and inversion as well as basin modeling would be used to establish a common velocity model that not only yields reasonably correct description of geopressure but also an improved subsurface velocity model that yields better seismic image at correct depths.

GEOPHYS 214: Water Management in Agricultural Areas

The course will introduce the new generation of methods used for investigating groundwater systems. The primary focus would be on methods for estimating the components of the aquifer water balance, which are critical elements needed for reliable projections of future conditions. The structure of the course will be lectures followed by student presentations based on follow-up readings and working with the extensive dataset from the High Plains aquifer in Kansas. The course will draw heavily on the short courses and workshops Dr. Butler has presented to practicing professionals and students over the last 15 years.

GEOPHYS 217: Numerical Methods in Engineering and Applied Sciences (AA 214A, CME 207)

Scientific computing and numerical analysis for physical sciences and engineering. Advanced version of CME206 that, apart from CME206 material, includes nonlinear PDEs, multidimensional interpolation and integration and an extended discussion of stability for initial boundary value problems. Recommended for students who have some prior numerical analysis experience. Topics include: 1D and multi-D interpolation, numerical integration in 1D and multi-D including adaptive quadrature, numerical solutions of ordinary differential equations (ODEs) including stability, numerical solutions of 1D and multi-D linear and nonlinear partial differential equations (PDEs) including concepts of stability and accuracy. Prerequisites: linear algebra, introductory numerical analysis ( CME 108 or equivalent).

GEOPHYS 218: D^3: Disasters, Decisions, Development (EARTHSYS 124, ESS 118, ESS 218, GEOPHYS 118, GS 118, GS 218)

This class connects the science behind natural disasters with the real-world constraints of disaster management and development. In each iteration of this class we will focus on a specific, disaster-prone location as case study. By collaborating with local stakeholders we will explore how science and engineering can make a make a difference in reducing disaster risk in the future. Offered every other year.

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.
Terms: Win | Units: 3-5

GEOPHYS 222: Reflection Seismology (GEOPHYS 182)

The principles of seismic reflection profiling, focusing on methods of seismic data acquisition and seismic data processing for hydrocarbon exploration.
Last offered: Autumn 2015

GEOPHYS 223: Reflection Seismology Interpretation (GEOPHYS 183, GS 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. ( Geophys 183 must be taken for a minimum of 3 units to be eligible for Ways credit).
Last offered: Spring 2016

GEOPHYS 224: Seismic Reflection Processing

Workshop in computer processing of 2D and 3D seismic reflection data. Students individually process a seismic reflection profile (of their own choice or instructor-provided) from field recordings to migrated sections and subsurface images, using interactive software (OpenCPS from OpenGeophysical.com). Prerequisite: GEOPHYS 222 or consent of instructor.
