Side Scan Sonar

For archaeological work and in particular the detection of wrecks and other objects of archaeological interest, we operate a Klein 3000 Side Scan Sonar.

The so-called towfish is towed at small distance above the sea bottom, while emitting high frequency acoustic signals.  The signals are reflected off the sea bed and transformed by the sonar software into digital images of the sea bed.

In this way, objects on the sea floor become visible.

For sonar operations, the catamaran ADA REBIKOFF was equipped with an hydraulic winch and 2300 metres of sonar cable, thus allowing sonar operations up to around 900 metres in depth.

The winch allows the cable length to be adjusted at all times in order to guarantee towing the sonar at the ideal distance from the sea bed, resulting in optimal image quality.

The sonar software receives the geographical position automatically from the DGPS receiver. This allows navigation along pre-defined tracks and to make the search paths visible on the sea chart.
