The AA201 boomer plate is used with a high-resolution seismic system
The boomer plate produces a repeatable pulse in the 1-6kHz frequency range using an electrodynamic transducer that can be powered by a capacitor discharge system. It has a penetration on the order of 150 m (depending on sediment type) and provides a balance between resolution and penetration. It can be used in freshwater lakes where a sparker would not be suitable.
Seismic sounds sources need to be used with some form of “listening”/recording device. Examples include a Geometrics GeoEel multi-channel hydrophone streamer, or an Applied Acoustics hydrophone streamer
See the multichannel seismic system for a comprehensive description. Also, check out the PCMSC Marine Facility (MarFac) web site for more information about field gear.
