Acoustics Group, is designed to maximize performance and resolution in shallow brown water or turbid environ- ments, and can be mounted on a vessel or submerged into the water on a tripod to conduct its scans.

Boh Bros. Construction Co., L.L.C., an established con- struction firm specializing in industrial and commercial projects, marine construction, dock work and bridges, is under contract with the U.S. Army Corps of Engineers to remove obstructions and debris from the bottom of the canal. "Our Acoustic Imaging Group utilizes the most advanced technologies in imaging data collection and visualization," said Kam Movassaghi, Ph.D., P.E., presi- dent Fenstermaker. "The devastating hurricanes of the past several weeks have tested the resources of the state of

Louisiana and its people. We are pleased that we are able to use this advanced technology to assist government agencies and businesses in this tremendous recovery effort."

SeaBat 7128

The SeaBat 7128 is designed for underwater imaging applications on a surface vessel, ROV or AUV platform to water depths of 6000 m. The sys- tem is a single and/or dual frequency (200/400 kHz) forward-looking sonar. In the 200 kHz configuration, the receiver covers a 130 degree x 27 degree field of view, with a typical range of 500 m (in the 200 kHz con- figuration) or 200 m (in the 400 kHz configuration). The SeaBat 7128 is capable of producing digital data, either pre-beamformed (hydrophone channel) or beam data. The data stream is operator configurable.
