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.

High-Resolution Multichannel Seismic System
Description of the high-resolution multichannel seismic system at the Marine Facility (MarFac) of the USGS Pacific Coastal and Marine Science Center, for seafloor mappingPCMSC MarFac Field Equipment and Capabilities
Learn about the USGS Pacific Coastal and Marine Science Center Marine Facility’s vast array of field equipment, sampling devices, and mapping systems, and our capabilities. Our engineers, designers, mechanics, and technicians have also designed and developed some of the specialized field equipment we use in field operations in the nearshore, in the deep sea, and on land.PCMSC Marine Facility (MarFac)

The GeoEel is a multichannel digital streamer system, with hydrophones in a long, green hose. The streamer is towed like a long snake in the water from a vessel, and the hydrophones "listen" for and record the signals from the seismic sound source.Seismic sound source power supply
