Ziel der Reise / Objectives of Cruise:
A towed array for the acoustic detection of small targets was to be tested. This towed array was constructed in form of a triplet array. With such an array a distinction between an echo coming from the starboard or the port side can be made possible. For these experiments deep water and good weatherforecasts are needed. This is given in the Sogne-Fjord. To conduct these acoustic experiments a transmitting buoy was placed in the fjord, while the towed array was driven by the ship. The trials which were conducted in the Sogne-Fjord should determine the a) acoustic properties of the towed array b) mechanic behaviour when towed at different speeds c) measurement of the flow noise d) right/left distinction of sound during measuring the roll angle of hydrophone sets
