Wassertiefenabhängige Auftriebsschwerpunktregelung für seitlich versetzt geschleppte Schwingerträger
The noise emission of the vessel, especially in shallow waters, causes a fright reaction of the fishes near thevessel. To reduce the uncertainty of hydroacousticmeasurements connected with that fact, a side shiftedtowed body is used for the hydroacoustic stockestimation in the Baltic sea. If the towed body wasrunning close to the surface it was quite sensitive towaves. To make the running properties of the side shiftedtowed body more robust a control of the center ofbuoyancy depending on the diving depth was introduced.The goal was set to control the towed body without additional energy supply. First results are shown.
