Target strength measurements of fish
(Journal article; Peer reviewed, 1977)
During the summer of 1971, target strength measurements of fish were made at two frequencies, 38 kHz and 120 kHz. The relationships between dorsal aspect target strength and fish length were worked out for four species. ...
Spatial shifts in spawning habitats of Arcto-Norwegian cod related to multidecadal climate oscillations and climate change
(Journal article; Peer reviewed, 2008-06-02)
Arcto-Norwegian cod tend to produce strong year classes in warm years and poor year classes in cold years. This work shows that spawning intensity at various spawning sites along 1500 km of Norwegian coast is also influenced ...
