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 |
