24-channel Shallow Seismic Reflection Instruments
Through an NSF Instrumentation grant, we have recently purchased
high-resolution shallow seismic reflection/refraction equipment for
use in active geophysical experiments. This includes:
- Geometrics Strataview 24-channel seismograph
- 18-bit digitizer
- Sampling rate 31-2000 microseconds
- Digital acquisition and display filters
- Signal stacking and correlation
- 486DX33 CPU with 420 Mbyte hard disk
- LCD display, thermal printer, floppy disk drive
- 25 100-Hz geophones, with cables
- 50 40-Hz geophones with 48-takeout cables, roll box
- sledgehammer and "Buffalo gun" sources
- wagon fitted with cable spools, wagon for equipment
- EavesDropper3 processing software for PC
- SU (Seismic Unix) processing software for Unix workstations
To date, the equipment has been used primarily in teaching, particularly
in the Applied Geophysics class (GEOL 453/553). We anticipate that as
graduate students become familiar with the safe use of the equipment,
its use in research in areas such as sedimentology, neotectonics,
hydrology and seismology will increase.
