Magnetometers are used to measure the strength of the
magnetic field. This
field is caused by a combination of the large magnetic field of the Earth
and smaller magnetic fields of near surface ferrous objects.
This technique can be used to locate
subsurface utilities, underground storage
tanks (USTs), unmarked graves, trenches, and
foundations.
The Near
Surface Geophysics Lab at Kutztown owns a
Geometrics
G-858 Cesium Vapor Magnetometer with Dual Sensors for measuring the
magnetic field gradient.
The Lab also has two
G-857 Proton Precession Magnetometers, one of which was donated by the Las
Vegas branch of the Environmental Protection Agency (EPA).
The mapping software
Oasis Montaj
and
Surfer are used
to plot and process the data at KU.
