Course work |
Each student will be responsible for leading 3 hours of presentations on a
specific week, using papers on a specific topic and explaining the concept using
SUNix and or OmegaSPS. Students should be quick (by middle of September) to
establish a reading list of 10-20 papers on their specific topic and think of
example hands-on exercises ASAP. These papers should be distributed to the
rest of the class and instructor in advance of the week in which the student
will lead the seminar classes.
Students will also be assigned short questions to research and present to the
class on a regular basis.
In the manner of a tentative guide,Tuesdays will be dedicated to the presentation of theoretical concepts and
Fridays will be dedicated to presenting hands-on exercises.
On weeks where the instructor leads the meetings, Fridays will be dedicated
to hands-on learning using SUnix and OmegaSPS and to short 5-minute
presentations to the whole group by each of the students on the current state of
their project.
In addition to the topics suggested in the outline below, students are
encouraged to include topics of their own interest to be addressed at regular
meetings. |

Recommended Pre-requisites
understanding of basic structural geology,
basic stratigraphy, algebra, trigonometry, basic PC/Mac manipulation, Web
navigation using freeware browser. Willingness to learn UNIX-flavored operating
systems, SUnix and OmegaSPS seismic processing systems. Course Grades: Final letter grades are calculated using
the results of performance in leading weekly sessions and presenting updates of
their projects and participating in discussions. 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 than undergraduates commensurate with their academic seniority. |
