The acoustic view into the sediment helps during archaeological, geological and military tasks
The Subbottom Head features a Tritech dual-frequency Seaking Parametric SBP (Subbottom Profiler) that emits a 20 kHz pulse using a primary frequency of 200 kHz.
- The profiler emits the sound vertically downward towards the seafloor and receives the return of the sound once it has been reflected.
- Parts of the sound will penetrate the seafloor and thus be reflected by the different subbottom layers and embedded objects.
- The data obtained by using the Subbottom Head provides information on the different sub-floor sediment layers.
For a quick visualisation of the mission results, the package includes dedicated Tritech Seanet Pro Software.
