Course Objectives: Field geophysical skills will be developed through a combination of lecture and practical field exercises with an emphasis on the latter. Techniques to be covered are those used in resource exploration, environmental studies, engineering, and archaeology, and include: seismic refraction, gravity, magnetics, electrical resistivity, electromagnetic methods, ground penetrating radar, and earthquake seismology. Laboratories will consist of field experiments and computer modeling/interpretation exercises.

General course goals:

1) gain knowledge of geophysics and proficiency in using geophysical instruments

2) present quantitative interpretations of geophysical data

3) learn which geophysical techniques are appropriate for a given problem

4) develop ability to successfully execute a geophysical experiment

Student responsibilities:

1) PARTICIPATE IN ALL LABS AND FIELD EXERCISES

2) present laboratory reports on these field exercises as assigned

3) Grads (5714) - execute an independent field experiment and present a report

4) This is a field course so come prepared! Sturdy shoes, rain gear, hat, sunscreen, snack, water, etc. Other helpful things to bring - calculator, clipboard.

Prerequisites: GEOL 2700, MATH 1300, PHYS 1110, or instructor consent. No previous knowledge of geophysics is assumed.

Text: Geophysical Exploration of the Shallow Subsurface,Burger (required). Somewhat elementary but extremely clear explanations. Includes useful Macintosh software.
Field Geophysics, 2nd edition, Milson (supplemental). Field sized reference guide. Contains info on many different techniques, but the summaries can be somewhat cryptic. On reserve in Benson Earth Sciences Library.
Applied Geophysics, 2nd Edition,Telford, Geldart, and Sheriff (supplemental). Comprehensive reference guide for the serious geophysicist.

Grading: Grading for GEOL 4714 (Field Geophysics) will be based upon four major areas (five for graduate students). Elaboration on these areas is given below.

1) Data collection - 25%. Attendance and class (field) participation.

2) Field Notebook - 10%. A single set of field notes will be prepared for each measurement type being made. Responsibility will be rotated through all studnts and grading will be for neatness, completeness, clarity, and accuracy.

3) Data reports - 40%. Prepare neat reports which include statement of problem that was investigated, explanation of procedures used, presentation of data, analysis, interpretation.

4) Practical exam - 25%. Written exam over material covered.

Graduate students (GEOL 5714) will also be responsible for an independent field project and presentation, which will account for 20% of the grade in GEOL 5714.
