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
