ParaSound Sub Bottom Profilers

Benefits:

• ​High resolution geophysical surveys are possible in parallel to seismic or bathymetric survey campaigns at virtually any seastate with the hull-mounted ParaSound in contrast towed sonar solutions.
   
• With its 4.5° beam width, due to its 15 cm vertical sampling and especially because of innovations like its intelligent Quasi Equi-Distant (QED) multi-ping, the ParaSound delivers a unique data resolution and data density that unveils sub-sea structures at an unrivalled data clarity and reliability.
  ​
• DDT and ParaSound's ability of in-parallel water column imaging is utilized extensively in ocean science, for example to search and locate accurately Gas Hydrates due to proof of gas in water column, due to clear imagining of fault structures, of free gas and of gas hydrates in the sediments.​​​

The ParaSound is the most advanced hull-mounted parametric sub-bottom profiler in the market. It utilises the parametric effect to generate a low-frequency secondary signal by emitting two primary signals of higher frequencies.

In comparison with traditional towed systems, the ParaSound family offers a very narrow transmission angle and greater positioning accuracy as well as higher operational speed and availability. Our sub-bottom profilers are suitable for operations beyond the continental rise into the abyssal plains and down to the deep ocean trenches.

Two product variants – depending on bottom penetration requirements – are available:
 

ParaSound P35

Due to its 35 kW transmission power, the ParaSound P35 provides a depth range from 10 m to 11,000 m and sediment penetration of more than 150 m.

ParaSound P70

Due to its 70 kW transmission power, the ParaSound P70 provides a depth range from 10 m to 11,000 m and sediment penetration of more than 200 m​.
