BOOMER SEISMIC ACQUISITION
In the OGS I have collected seismic data around the world. In the last years I
collaborated in several project for acquiring high resolution seismic data in
water. The acquisistion system is a boomer composed by a power
unit (Pulsar2002-CEA), an electro-dynamic transducer (UWAK-NAUTIK) and a
mono-channel streamer (EG&G and GEO-RESOURCES). The maximum impulse rate is 8
pulses/second at 150 Joule but I use only 2-3 pulses/s. The source is mounted
on a catamaran frame that allows the plate to be suspended at a constant depth
of 30 cm, leading to a strong reduction of dragging turbulence.The active
section of streamer (8 hydrophones) is 2.8 m. A navigation system (Navpro-COMMUNICATION
TECHNOLOGY) is used together with a DGPS. The acquisitor is SB-Logger (TRITON)
a 24 A/D, in the past I used Delph2.
Now we have a second one boomer: AAE A301!
Signature I measured the boomer signature
with 8103 Bruel & Kjaer.
It's not bad. The signal is a good spike and has a good repeatibility.
Portability The Pulsar is not light
(70kg) but all system can be put in little boats.
