Course Book: John M. Reynolds 2nd Edition

An Introduction to Applied and Environmental Geophysics by John M. Reynolds, 2011, 696 pp. Second Edition.

Learning Goals:

Shallow earth geophysics is an important in the areas of civil engineering for monitoring and remediation and management of natural resources including ground water. This course will provide an overview of some of the key geophysical principles and methods (“seismics, and DC resistivity”) for solving societal and scientific problems originating in the upper 30 m of the Earth. During spring 2023, we will take measurements in either a laboratory sand tank, or if the weather permits, on the flood plain of the Mississippi on LSU’s campus using (1) Ground Penetrating Radar and seismic methods to collect (2) surface waves (3) reflected, (4) refracted waves (5) and electrical resistivity readings.

Course work


Lecture sessions will cover key concepts from the textbook.   Labs will be dedicated to collecting and interpreting geophysical data.

Labs will involve learning basic use of MATLAB, and linux.   ( 3 lab exercises, 40 % of final grade)

The last week that each major topic is covered (I-GPR, II-Seismology, III-Electrical resistivity,  there will be short (5-10 minute) presentations by team groups on interesting applied cases of the technique.   (30 % final grade)

Midterm-takehome (30% final grade)

All written assignments, are due at the start of the assigned 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. Late submissions will receive no course credit.

Recommended prior courses or experience  Highly Recommended: Physics-I.
 Advisable: programming experience with a high-level language like Excel, Matlab or Maple, Mathematica are useful but not mandatory
 Required: GEOL 3071 and MATH 1552 or permission of instructor. 2 hrs. lecture; 3 hrs. lab.
 

Assessment Policies

Final letter grades are calculated using the results of in-class presentations (20%), lecture and lab  homeworks (60%) and one midterm exam (total of 20%).  In-class quizzes, presentations and participation can provide up to 5% bonus points. A-: 90-93.3, A: > 93.3-96.7, A+: > 96.7-100%) , 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

Academic Integrity
Louisiana State University adopted the Commitment to Community in 1995 to set forth guidelines for student behavior both inside and outside of the classroom.  The Commitment to Community charges students to maintain high standards of academic and personal integrity.  All students are expected to read and be familiar with the LSU Code of Student Conduct and Commitment to Community, found online at lsu.edu/saa.  It is your responsibility as a student at LSU to know and understand the academic standards for our community. Students who are suspected of violating the Code of Conduct will be referred to the office of Student Advocacy & Accountability.  For undergraduate students, the outcome will range from failing the assignment to failing the class along with disciplinary probation. For graduate students, a first violation leads to deferred suspension for at least two semesters and a failing grade in the course.
Plagiarism and Citation
As a student at LSU, it is your responsibility to refrain from plagiarizing the academic property of another and to utilize appropriate citation method for all coursework. Ignorance of the citation method is not an excuse for academic misconduct.  Remember there is a difference between paraphrasing and quoting and how to properly cite each respectively. One tool available to assist you in correct citations is the “References” function in Microsoft Word.  This program automatically formats the information you input according to the citation method you select for the document.  This program also has the ability to generate a reference or works cited page for your document. The version of Microsoft Word with the “References” function is available in most University computer labs. A demonstration of how to use this tool is available online at www.lsu.edu/saa.
Rights and Student Resources Nondiscrimination, Sexual Harassment and Title IX
LSU provides equal opportunity for all qualified persons in admission to, participation in, or employment in the programs and activities which the university operates without regard to race, creed, color, marital status, sexual orientation, gender identity, gender expression, religion, sex, national origin, age, mental or physical disability, or veteran’s status. LSU has implemented a procedure to address complaints for those who believe they have been subjected to discrimination and/or harassment in violation of this policy. Please know that your instructors are here to support you and listen to your experience. We also want you to know that we are mandatory reporters and must report what we know to the Office of Civil Rights and Title IX. All LSU employees, with few exceptions, are required to report instances of sex- or gender-based harassment and discrimination, including sexual misconduct and power-based violence (e.g., sexual assault, stalking, dating violence, domestic violence, sexual exploitation, retaliation, etc.) for which they may not be the victim, but of which they are aware. The Office of Civil Rights & Title IX is the LSU office responsible for investigating complaints regarding any type of discrimination, sexual harassment, or power-based violence. The Office of Civil Rights & Title IX is located in 118 Himes Hall and the phone number is (225) 578-9000. If you are aware of an individual who has been victimized, you are encouraged to contact the Office of Civil Rights & Title IX or file an online report by visiting LSU’s Domestic & Sexual Violence Support and Reporting website and clicking the Report an Incident box. If you have been assaulted, harassed, or a victim of violence, we encourage you to contact the Office of Civil Rights & Title IX. Please reach out for help immediately. Some excellent resources available to Baton Rouge residents include:
•    STAR (Sexual Trauma Awareness and Response; 24/7 hotline: (855) 435-STAR (7827)
•    IRIS Domestic Violence Center; 24/7 hotline: (800) 541-9706
•    The Lighthouse Program; (225) 578-5718
•    VIA LINK; (800) 273-TALK (8255) [national line but answered from New Orleans]
National resources include:
•    RAINN (Rape, Abuse & Incest National Network); 24/7 hotline: (800) 656-4673
•    National Sexual Violence Resource Center
