Learning Goals:

Students will learn to document the (1) background, (2) purpose and (3) function of chosen seismic survey techniques and algorithms,to enhance 2D seismic images of buried geological structures. They will communicate this knowledge through visual representations of the algorithms and formal technical description tools (e.g. pod, an html-like language for embedding embedded documentation within within Perl-coded programs)


Course work

--Bi-monthly lecture homework, lab homework, a field-based seismic processing project (Visual communication skills), and two midterm  exams. 

 Each homework usually takes 3-4 hours to complete.  One of the lab homeworks will be used to emphasize technological communication skill sets.  

Lectures  will be dedicated to the presentation of concepts covered by the course textbook and Labs will be dedicated to exercises using academic seismic processing software in the Subsurface Laboratory (E217).   In order to engage in reflective discussions during lecture times, students will complete online linux and perl tutorials and power-point class exercises prior to meeting times.

Lab work will include processing of an unpublished seismic data set collected by LSU students and faculty .  All homeworks and lab exercises, with the exception of the final project, are due one week after they are handed out, at the beginning of each class, typed and printed on paper using full English grammar and syntax to explain the full reasoning process behind mathematical and physical derivations, including references.

Recommended prior courses or experience Math I, II, Physics-I, programming experience with a high-level language like Excel, Matlab or Maple, Mathematica, etc.
 

Course Grades

Final letter grades are calculated using the results of weekly lecture homework and lab exercises and homeworks (30%), two midterm exams (total of 20%), one technological communication project (25%) a visual communication project  (25%).  In-class quizzes, presentations and participation can provide up to 5% bonus points. A-: 90-93.3, A: > 93.3-96.7, A+: > 93.7-100%) , B-: 80-83.3, B: > 83.3-86.7, B+: >86.7 - 90%, C-: 60-63.3, C: >63.3-66.7, C+:>66.7-80%;  D-: 50-53.3%, D: >53.3-56.7, D+: >56.7-60%), F (less than 50%) Graduate students taking this course will be held to a higher standard, commensurate with their academic seniority.

Academic Standards and Expectations What is LSU Commitment to Community?  What is Plagiarism?  What is Academic Misconduct?

This course is certified as a Communication-Intensive Courseand meets all of the requirements explained on the CxC Web site., including the following: Emphasis on formal and informal assignments in written and visual communication, class time spent on communication, 40% of the final grade based on communication projects, revisions after faculty feedback on 2 formal projects (one for each emphasis), and a student/faculty ratio of 35:1. Because it meets these requirements, students may count it toward Distinguished Communicator Certification on LSU transcripts.

Communication Intensive Assignments

VISUAL EMPHASIS
(written minor component)
TECHNOLOGICAL EMPHASIS

Informal Activities

Students will sketch conceptual models to describe physical processes attending wave propagation During lab sessions, students will complete lab assignments modifying existing programs to achieve specific goals established in the handout of the day.

Formal Activities

Students will develop visual explanations to justify the use of different seismic algorithms and show, using resultant seismic images, the results of applying different parameters. A general flow chart is required to explain the overall goals of the project. A complete visual processing sequence  is required in the explanations of all of the processing stages. Students will develop software (using Perl and Seismic Unix) that will render best results at each processing stage for seismic data.  Each student will develop one existing seismic processing module with a Perl wrapper.  Each resultant module will be fully documented using in Perl documentation language.  Examples of each working module will also be provided by each student. 

Feedback

Draft-review-revise process will be implemented for developing an electronic document that includes generation of images to represent best-practices in the choice of processing parameters. Computer Code (from technological project) can also be included.
Each laboratory exercise (bandpass filtering and beyond) will form part of the overall Visual  Project.
Draft-review-revise process will be implemented on the module targeted for development, which will require students to program as well as generate technical documents.
