Introduction to Geophysical Exploration
Glossary of geophysics
- Glossary of Earthquake and Related Terminology (USGS)
- Glossary of Terms by UUSS
- Structured Geological Glossary: Geophysics
Principles of physics applied to geology, earth and environmental sciences, with emphasis on exploration of the shallow subsurface (~500 m). Topics include seismic method, electrical resistivity and electrical method, gravity, magnetic method, ground penetrating radar, and remote sensing. Geophysical instrumentation, data acquisition and analysis, and geologic interpretation of geophysical data. This course is for students who want to be practicing civil engineers, geologists, archaeologists, and environmental practitioners and/or scientists who need an knowledge and skills of modern geophysical methods relevant to their disciplines.
- Probing the subsurface
- Fundamentals of seismic exploration
- Seismic refraction method
- Seismic reflection method
- Electrical resistivity method
- Exploration using gravity
- Magnetic field method
- 1) To develop an understanding of the basic theory of each geophysical methods: seismic, electrical, gravitational, magnetic, and ground penetrating radar methods;
- 2) To develop an understanding of the principles of instrumentation for each method;
- 3) To develop the skills to measure the physical properties of the Earth materials using these methods;
- 4) To develop the capability to interpret the field data and apply these methods.
Course outcomings (complying with ABET A-K):
After this course, you should have
A. an ability to apply knowledge of mathematics, science, and engineering
K. an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice
Grade Policy: The final grade for the course will be determined approximately as follows:
- Homework: 20%
- Lab: 10%
- 3-5 Tests: 70%
Grading scale observes: A=(92,100], A-=[90, 92], B+=(87, 90), B=[83, 87], B-=[80, 83), C+=(77, 80), C=[73, 77], C-=[70, 73), D+=(67, 70), D=[63, 67], D-=[60, 63), F=[0, 60). [ or ] means inclusive, ( or ) means exclusive. Also: A= 4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, D-=0.7, F=0.
Homework will be assigned on Wednesday and due the following Wednesday. Some assignment will involve the use of computer programs. Group discussing is encouraged but copying answers from others is prohibited. Copied homework will be graded as “zero” or “F” for both parties.
