Quantifying the amount of fish unavailable to a bottom trawl by use of an upward looking transducer
(ICES CM documents, Working paper, 1999)When surveying demersal fish with a wide and variable vertical distribution, it is desirable to combine information from a bottom trawl survey with the information from a hydroacoustic survey into an absolute abundance ... -
Recommendations for the collection of multifrequency acoustic data
(ICES CM Documents;2004/R:36, Working paper, 2004)Traditionally, collection of acoustic data has been optimised for a single frequency, while requirements for the optimal combination of multifrequency data has been given less attention. Even though data manipulation can ... -
The relative frequency response, as derived from individually separated targets on cod, saithe and Norway pout
(ICES CM documents, Working paper, 2004)The relative frequency response is an important acoustic feature used to characterise acoustic targets. This response has been defined as the sv, volume backscattering coefficient, for a specific frequency relative to ... -
