Sammendrag
The surface layer. 0—15 m, will as a rule not be satisfactorly covered by ordinary hull mounted vertical echo sounder transducers. A side looking transducer has been tried onboard the R.V. »G. 0. .Sars». The transducer is stabilized for ship rolling by mouting it as a pendulum. The recordings obtained from near surface scatterers (small schools of capelin) are promising, and the pendulum transducer might be a useful support to the echo sounders and sonars during echo surveys.
