The Northeast Arctic cod stock's consumption of commercially exploited prey species in 1984- 1986
(Rapports et procès-verbaux des réunions, Journal article; Peer reviewed, 1989)In order to evaluate the growing influence of Northeast Arctic cod (Gadus morhua) on some commercially exploited prey species, the annual consumption of these species by the cod stock has been estimated for 1984-1986. ... -

Significance of advection for the carrying capacities of fjord populations
(Journal article; Peer reviewed, 1989-02-02)Advective rates of nutrients, phytoplankton and zooplankton were estimated for the Masfjord, western Norway, in June and October 1985. The advective contribution to the phytoplankton biomass formation was dearly less ... -
Flow cytometric characterization and enumeration of Chrysochromulina polylepis during a bloom along the Norwegian coast
(Journal article; Peer reviewed, 1989-06-22)Flow cytometry was used to count the concentration of the alga Chrysochromulina polylepis Manton & Parke during a bloom along the Western and Southern Norwegian coasts. Fresh samples could be counted without fixation ... -
Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHz
(Journal article; Peer reviewed, 1990)Encaged aggregations of live krill in good to pristine condition have been ensonified at 38 and 120 kHz. Concurrent underwater television observations of behavior resemble those made by underwater divers in naturally ... -
Correcting acoustic measurements of scatterer density for extinction
(Journal article; Peer reviewed, 1990)Extinction is sometimes a major problem in acoustic surveys of fish stocks, as it often occurs when the fish are concentrated and easiest to survey. The same may be true of certain macrozooplankton, such as krill in swarms. ... -
Day and night fish distribution pattern in the net mouth area of the Norwegian bottom-sampling trawl
(Journal article; Peer reviewed, 1990)A high-frequency scanning sonar, mounted as a net sonde, was used to study fish behaviour in the mouth area of the Norwegian bottom-sampling trawl. Fish distribution patterns were significantly different by day and night. ... -
Age determination of Northeast Atlantic Sebastes species
(Journal article; Peer reviewed, 1990)Uncertainty exists concerning the validity of age determination methods for redfish species owing to the various procedures in use. North American scientists routinely use otoliths, whilst European scientists have preferred ... -

Speed of sound in Euphausia superba
(Journal article; Peer reviewed, 1990)The speed of longitudinal sound waves in Antarctic krill has been measured by the time-of-flight method. The result of 17 separate measurement series on different assemblages of living krill is that the animal's sound speed ... -

Diel variations in photosynthetic activity of summer phytoplankton in Lindåspollene, western Norway
(Journal article; Peer reviewed, 1990-07-19)Diel patterns in photosynthesis of natural phytoplankton were studied during a 5 d period during midsummer in Lindbspollene, a land-locked fjord of western Norway. Samples were taken from depths of 0.5, 5, 10 and 21 m ... -

Mass sedimentation of Phaeocystis pouchetii in the Barents Sea
(Journal article; Peer reviewed, 1990-09-06)Mass sedimentation of gelatinous colonies of the prymensiophyte Phaeocystis pouchetii were observed in the upper 100 m of Atlantic water in the central Barents Sea. Sedimentation rates of particulate organic carbon and ... -
Predation by copepods upon natural populations of Phaeocystis pouchetii as a function of the physiological state of the prey
(Journal article; Peer reviewed, 1990-11-01)Conflicting data have been previously presented on the ability of copepods to prey upon the prymneslophyte Phaeocystis pouchetii. While some have suggested that gelatinous colonies of this species contain biochemical ...
