Profile: Hydroacoustics, Inc. specializes in the engineering and manufacture of unique high power, broadband, low frequency underwater acoustic sources based on continuous wave & impulsive source technology. Our product line includes hydroacoustic low frequency (HLF) sources, single and Multipulse™ air gun systems, marine vibrator units (MVUs) and the latest technology in underwater remotely operated vehicles (ROVs). Our products are widely applied in anti-submarine warfare (ASW), mine countermeasures (MCM), port security, law enforcement, protection of high risk & high value assets, underwater surveillance & exploration, search, rescue & recovery, and anti-terrorist & force protection. Hydroacoustic technology is applied in the fields of industry & science, particularly in the areas of marine seismic exploration, underwater engineering surveys, and propagation & environmental measurement. We have developed a continuous impulse source system that is extremely effective in the detection, exploration and assessment of underwater physical characteristics. Examples include the underwater search for oil and natural gas resources. Additional applications involve exploration and examination of the earth's surface beneath oceans & lakes. We have systems designed for high-resolution surveys of sub-surface bottom profiles. These systems are used in identifying underwater earthquake fault lines, and in the construction of bridges, piers and other over & underwater facilities.
