Course
Description : |
|
| |
This
course provides an opportunity for undergraduate
and graduate students to study the emerging environmental
problem known as unexploded ordnance (UXO) contamination.
Geophysical methods have played a key role in
the detection and recovery of ordnance throughout
the world. Students will be introduced to the
scientific and social issues of UXO contamination
and to the currently implemented geophysical methods
for detecting UXO. The students will receive theoretical
and practical instruction on both the magnetic
and electromagnetic methods. Students will study
the field procedures for data acquisition, qualitative
data processing methods for UXO detection, and
advanced algorithms for UXO discrimination. The
course has an equal emphasis on theoretical training
and hands-on experiences.

-
Students
will use a variety of magnetic and EM instruments
to acquire data over UXO test grids, process
acquired and instructor supplied data to complement
lectures and gain practical experiences. They
will use Matlab, UXOLab, and software available
via the campus network to process and analyze
data.
