| dc.description.abstract | The difference-frequency band of the Kongsberg TOPAS PS18
parametric sub-bottom profiling sonar, nominally 1–6 kHz, is being used to
observe Atlantic herring. Representative TOPAS echograms of herring layers
and schools observed in situ in December 2008 and November 2009 are presented.
These agree well with echograms of volume backscattering strength
derived simultaneously with the narrowband Simrad EK60/18- and 38-kHz
scientific echo sounder, also giving insight into herring avoidance behavior in
relation to survey vessel passage. Progress in rendering the TOPAS
echograms quantitative is described. | en_US |
