Description:
Geophysics
is the application of physical principles to the study of the Earth’s structure
and physical properties.Exploration or applied geophysical techniques are
used to determine the physical properties of the subsurface from measurements
made by instrumentation placed on the surface or in boreholes in the ground.These
techniques were first developed as an aid in the exploration for mineral
and petroleum deposits but in recent years, they have been increasingly
applied to environmental problems such as hydrogeology and site remediation.
Applications of geophysical methods include the determination of subsurface
stratigraphy and soil properties, characterization of groundwater flow
and storage, the identification and tracing of hazardous substances and
contaminants in the subsurface, the detection of buried objects and unexploded
ordinance, the characterization of soil and bedrock properties for stability,
and the exploration of the subsurface for valuable mineral and energy resources.
This course will provide an introduction
to the basic methods used in exploration and environmental geophysics.Topics
include seismic methods, potential fields, electrical methods, ground penetrating
radar (GPR), borehole methods, introductory surveying and GPS, and introduction
to GIS.The course includes a lab section held on Fridays in PC 325.The
lab will include 3-4 field trips to sites in Miami-Dade County and will
also include exercises on data reduction, modeling, interpretation, and
computerized map production.The lab is an essential part of this course
and is required
for all students.The final grade will be based on labs, homework,
and exams.
