dc.description.abstract | 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. 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. | en |
