When fish descend, their swimbladders may or may not become compressed/deformated by increasing pressure. This may result in true differences in acoustic back...
Sound attenuation within dense aggregation of fish may cause a problem for abundance estimation by echo integration. Indications of the occurrence of this...
In this paper are reported some experiments carried out with the intention to collect information of the possible importance of such behaviour phenomena in...
Fjord plumes accumulate to form the Norwegian Coastal Current (NCC) that due to geostrophic forcing runs northwards on the Norwegian shelf. Three monthly...
Target strength and acoustic back scattering characteristics of herring, when swimming at different depth, have been experimentally investigated. The echo...
