dc.description.abstract | The possible use of vessel heave as a correction indicator for air
bubble attenuation of acoustic signals from hull mounted transducers is
investigated. Vessel heave was monitored along with the echo energy from the
air bubble layer close to the transducer surface. Initial comparisons under
different weather conditions are presented. | no_NO |
