Comparing Kirchhoff-approximation and boundary-element models for computing gadoid target strengths
(Journal article; Peer reviewed, 2002)To establish the validity of the boundary-element method (BEM) for modeling scattering by swimbladder-bearing fish, the BEM is exercised in several ways. In a computation of backscattering by a 50-mm-diam spherical void ... -
Depth-dependent target strengths of gadoids by the boundary-element method
(Journal article; Peer reviewed, 2003)The depth dependence of fish target strength has mostly eluded experimental investigation because of the need to distinguish it from depth-dependent behavioral effects, which may change the orientation distribution. The ... -
The fish swimbladder as an acoustic waveguide

Importance of the swimbladder in acoustic scattering by fish: A comparison of gadoid and mackerel target strengths
(Journal article; Peer reviewed, 1980)Previous determinations of the swimbladder contribution to the fish backscattering cross section have been hindered by ignorance of the acoustic boundary conditions at the swimbladder wall. The present study circumvents ... -
Variability in frontal zone formation and distribution of gadoid fish larvae at the shelf break in the northeastern North Sea
(Journal article; Peer reviewed, 1999-02-11)Hydrography and larval fish distribution in the northeastern North Sea were studied during a research programme carried out during the period from 1991 to 1994. The aim was to examine the connection between frontal zone ...
