SEG Distinguished Instructor Short Course | The SEG Distinguished Instructor Short Course (DISC) is an eight-hour, one-day short course on a topic of current and wide-spread interest. The SEG DISC is presented at over 25 locations each year around the world. Established in 1998, the DISC has attracted over 25,000 participants in its 14-year history. Selection as the DISC instructor is viewed as a major honor and recognition of excellence by the SEG. The instructor is a prominent geophysicist whose work and presentation appeal to a wide audience ranging from students and professionals.

*A one-day course touring worldwide in 2012. Elements of Seismic Dispersion: A somewhat practical guide to frequency-dependent phenomena Christopher L. Liner, University of Houston Course Description The classical meaning of the word dispersion is frequency-dependent velocity. Here we take a more general definition that includes not just wave speed but also interference, attenuation, anisotropy, reflection characteristics, and other aspects of seismic waves that show frequency dependence. At first impression, the topic seems self-evident: Of course everything is frequency dependent. Much of classical seismology and wave theory is nondispersive: the theory of P- and S-waves, Rayleigh waves in a half-space, geometric spreading, reflection and transmission coefficients, head waves, and so forth. Yet when we look at real data, strong dispersion abounds. This course is a survey of selected frequency-dependent phenomena that routinely are encountered in reflection-seismic data. Who Should Attend The course is framed along the lines of acquisition, processing, and interpretation to contain material of interest to the entire spectrum of seismic geophysicists. The mathematical level of the course is generally on the advanced undergraduate level, but deeper aspects often are included for advanced readers. Familiarity with the Fourier transform and related topics will be beneficial. In all cases, theoretical developments are illustrated by examples or case histories. | | | | |
