Stema EBP Systems Ultra-high resolution sub-bottom profiling
The EBP system has been developed to yield optimal results in the area
of 3 – 33 kHz sub bottom acquisition range.
• Easy to deploy and operate
• Multiple frequency range 3 – 33 kHz
• Easy to integrate in survey setup
Example of transducers used with EBP system to detect export and infield cables.
Silas profile recorded with EBP system to identify top and bottom of fluid mud layer.
Stema EBP Sub-bottom Profiler system.
Choice of transducers will be recommended to fit required result.
It offers the choice of transducers dependant on requirement and processes this via its unique
USB-A/D configuration to ensure the highest resolution of your data. With the full digitalization
of the signal the system enables full and quick import of the acquired data into the Silas
Software Suite, ensuring the high resolution transmission of data for full processing.
Ultra-high resolution sub-bottom profiling
• Ultra-high resolution sub-bottom profiling

High band: 100 kHz – 1 MHz
Low band: 3.5 kHz – 50 kHz
Output High band: 900 W RMS at 200 kHz
Output Low band: 2 RMS
110 or 220 V AC – 24 V DC, 120 W
Raw seismic wiggle (user select sampling rate)
Digitized depth levels (echo-sounder pre-sets)
Real-time density level (requires calibration)
• 3 – 7 kHz
• 10 – 14 kHz
• 24 / 33 kHz
• Depends on frequency and cycle selected
• 24 kHz 1 cycle < 10 cm
• 4 kHz 1 cycle < 40 cm
• Depends on soil type and frequency
• 24 kHz: clay / mud, typical 5 m
• 4 kHz: clay / mud, typical 10 – 20 m
• 4 kHz: sand, typical 5 m
