International Acoustic Survey on Blue Whiting in the Norwegian Sea, August 1984.
Six research vessels from the five nations, USSR, Norway, Faroe Islands, Iceland and GDR participated in the third ICES-coordinated acoustic survey on blue whiting in the Norwegian Sea and adjacent waters. By use of instrument constants obtained from calibration either against a standard target or w...
