Meridata's chirp sub-bottom profilers are characterised
by their ability of good penetration, ultimate resolution
and excellent image clarity in portraying sediment
The Meridata HD SBP includes one or two simultaneous wide
band chirp channels. Each channel supports transducers
with frequencies anywhere between 2 and 50 kHz. A dual
channel configuration allows the lower frequency channel
to maximize penetration while the higher frequency channel
optimizes layer resolution.
For extreme penetration in hard sediments, the system
includes coordinated shot control and hydrophone streamer
signal acquisition for boomer, sparker
or airgun sources, enabling single-pass surveys without
fear of interference between the acoustic systems.
Suitable system configurations are available for
operations in shallow inland water to full ocean depth.
20-50 kHz UHF Chirp transducer
The ultimate layer resolution of better than 3 cm in
densely varved fine sediments can be obtained using the
20-50 kHz UHF Chirp transducer.
10-20 kHz HF Chirp transducer
A balanced performer positioned between the other two
frequency bands, combining a layer resolution better than
10 cm and improved penetration.
2-9 kHz LF Chirp transducer
The best penetration can be obtained using the 2-9 kHz LF
Chirp transducer. Layer resolution is better than 20 cm.
These transducers are also available in array
configurations for extended range operation down to
several kilometers depth.
