Recommended Pre-requisites understanding of basic structural geology, basic stratigraphy, algebra, trigonometry, basic PC/Mac manipulation, Web navigation using freeware browser.

Course Grades: Final letter grades are calculated using the results of four (4) lab exercises (40%), a final open-book exam (30%) and a seismic acquisition and processing project (30%).  A (90-100%) , B (80-89.5%), C (60-79.5%) D (50-59.5%), F (less than 49.5%) Graduate students taking this course will be held to a higher standard, commensurate with their academic seniority.

Course Project: Seismic processing and interpretation of field data acquired by this class in the field
