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 R.V. "G. O. Sars". The transducer is stabilized for ship rolling
by mounting 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.
