Falmouth Scientific, Inc. (FSI), a Cataumet, MA, USA based designer and manufacturer of precision oceanographic instrumentation and systems, continues to grow their Sub-Bottom product line with the addition of the new HMS-AT650 Compact ULF Sub-Bottom Profiling System. It is ideal for applications that require high resolution CHIRP sub-bottom images along with deeper penetration in difficult sediments such as hard-packed sand.
The new Compact ULF System generates CHIRP signals in the 200 Hz to 2 kHz frequency range and is suitable for operation in a variety of array configurations to support many different shallow water sub-bottom profiling applications. It fills the application space between FSI’s Bubble Gun Family of Portable Seismic Systems and the rest of FSI’s CHIRPceiverTM compatible transducer offerings (see graphic below).

Components of the ULF System include a standard single or dual frequency CHIRPceiverTM, a dedicated ULF Matching Driver, the HMS-AT650 transducer, and a specialized hydrophone streamer. The transducer can be either mounted on a rigid support or towed behind a small vessel using the optional vehicle shown in the photo.
Falmouth Scientific offers other sensor-based products such the PLUS Family of current, wave, and tide meters and other acoustics-based underwater instrumentation. Service areas include custom design, development, integration, and production of marine systems and acoustic transducers.
