Ge 111ab: Applied Geophysics Seminar and Field Course
Summer 2002 Field Camp Location: Fish Lake Valley, Dyer, NV.
Course Description
An introduction to the theory and application of basic geophysical
field techniques consisting of a comprehensive survey of a particular field
area using a variety of methods (e.g., gravity, magnetic, electrical, GPS,
seismic studies, and satellite remote sensing). The course will consist
of a seminar (Ge 111a) held in the spring quarter in which we will discuss
the scientific background for the chosen field area, along with the theoretical
basis and implementation of the various measurement techniques. The field
course (Ge 111b) will take place soon after commencement.
Units: 3-3-0 (spring), 0-3-6 (summer). The seminar
is graded, with auditing not permitted; The field course must be taken
for a grade and the seminar is required for participation in the field
component.
Prerequisites: Consent of Instructor(s) Spring/Summer
2002
The field course will take place from Sunday, June 16
to Saturday, June 22. Reports will be due 5pm Wednesday, June 26.
We will be camping near Fish Lake Valley for the entire field course. The course schedule for spring 2002 is at the bottom of this web page, and updated whenever any changes occur.
