GEOPH 326 - Seismic Imaging of Earth's Interior

3 units (fi 6)(EITHER, 3-0-3/2)

Use of reflection and refraction seismology to image the Earth's interior, including application to environmental assessment, mineral and hydrocarbon exploration, geothermal energy, and tectonics; study of current technologies used to acquire, image, and interpret 2D and 3D data sets. Real data sets and computer assignments will be used to produce seismic images of the subsurface. Prerequisite: MATH 215 or 209 or 315 or 317 or MA PH 351.

GEOPH 431 - Geophysical Inverse Theory

3 units (fi 6)(EITHER, 3-0-0)

Quantitative methods to determine the physical properties of the Earth from indirect geophysical observations; formal treatment of geophysical inverse theory; topics include linear and nonlinear inverse problems, regularization techniques, model norms and misfit, tomography, and case histories of interpretation and analysis. Prerequisites: MATH 311. Note: credit may only be obtained for one of GEOPH 431 and GEOPH 531.

GEOPH 526 - Signal Analysis in Geophysics

3 units (fi 6)(EITHER, 3-0-0)

Application of time-series analyses and image-processing techniques to large geophysical data sets; sampling and aliasing of signals; one- and two-dimensional Fourier transforms; the Z transformation; spectral analysis, filtering, and deconvolution; application of 1D and 2D filtering to geophysical data analysis, processing, and decomposition. Note: credit may only be obtained for one of GEOPH 426 and GEOPH 526. Prerequisite: Consent of instructor.

GEOPH 531 - Geophysical Inverse Theory

3 units (fi 6)(EITHER, 3-0-0)

Quantitative methods to determine the physical properties of the Earth from indirect geophysical observations; formal treatment of geophysical inverse theory; topics include linear and nonlinear inverse problems, regularization techniques, model norms and misfit, tomography, and case histories of interpretation and analysis. Note: credit may only be obtained for one of GEOPH 431 and GEOPH 531.
