| The Barlow FDEM-8 is a
"loop-loop" frequency domain electromagnetic
(FDEM) measurement instrument. The system consists
of two coils, a transmitter (Tx), and receiver(Rx).
The depth of imaging is controlled by the coil spacing,
frequency of the signal, and power of the instrument.
Readings take approximately 15 seconds in total to cycle
through 8 frequencies - Both in-phase and quadrature
components (amplitude & phase) are measured for
each of the 8 frequencies. Combining the data for all 8
frequencies allows the operator to create a
pseudo-section along the survey line. During the survey
the data is displayed on an LCD screen, allowing the
operator to get an idea of the data quality, signal
strength, and structure of the underlying geology. The
Barlow FDEM-8 is supplied with basic display and plotting
software. Data can be saved in formats suitable for use
with Surfer for Windows and common spreadsheets. Typical applications include ground water exploration, landfill mapping, environmental investigations (contaminant plume mapping), archaeological mapping, geological engineering, mineral exploration (sulfide mapping), and more. |
The Barlow
DCRES-200 resistivity system uses periodically
inverted direct current to measure the apparent
resistivity of the earth. Typical applications include detection of horizontal layering, ground water exploration (geohydrology), mineral exploration, environmental (pollution and seepage mapping), cavity mapping (sinkholes, caverns), salinity mapping in aquifers, archeological mapping, and more. |
