Sedimentation of particulate organic matter and silicium during spring and summer in Lindaspollene, Western Norway
(Journal article; Peer reviewed, 1986-04-24)Sedimentation of organic and inorganic matter was determined at 18, 38, 70 and 85 m between 17 March and 8 October 1982, m the land-locked flord Llndespollene Rates of sedimentation were highest dunng spnng with 2 peaks ... -
Influence of some physical and biological factors on the density and vertical distribution of Atlantic halibut Hippoglossus hippoglossus eggs
(Journal article; Peer reviewed, 1986-10-27)ACT: Atlantic halibut Hippoglossus hippoglossus (L.) eggs were sampled using a Tucker trawl and a MOCNESS-sampler at 3 selected localities in North Norway. The specific density of the eggs was determined in a density-gradient ... -
Performance of the parametric receiving array: Effects of misalignment
(Others, 1987)The difference frequency sound field from two concentric but misaligned, axisymmetric, planar transducers in a nondissipative and nondispersive medium is developed as a special case of the general theory [Garrett et al., ... -
Fish target strengths for use in echo integrator surveys
(Journal article; Peer reviewed, 1987)In situ measurements of fish target strength are selected for use in echo integrator surveys at 38 kHz. The results are expressed through equations in which the mean target strength TS is regressed on the mean fish length ... -

Consumption of silicic acid below the euphotic zone by sedimenting diatom blooms in the Barents Sea
(Journal article; Peer reviewed, 1987-03-23)Massive sedimentation of spring phytoplankton blooms occurs in the Barents Sea as in many other shelf sea environments. Associated with this sedimentation there is a large decrease in concentration of dissolved shcic ... -

Screening of Norwegian lobsters Homarus gammarus for the lobster pathogen Aerococcus viridans
(Journal article; Peer reviewed, 1987-12-14)Hemolymph samples drawn from 3044 lobsters trapped along the southwestern part of the Norwegian coast in the period 1981 to 1984 were individually examined for Aerococcus viridans, the causative agent of gaffkemia. In ... -
Morphological and ecological studies of Clavella adunca (Copepoda, Lernaeopodidae) on polar cod, Boreogadus saida
(Journal article; Peer reviewed, 1987-12-15)Clavella adunca (stroem, 1762) from the Barents Sea polar cod was studied. The general appearance and morphology of the appendages were similar to C. adunca f. iadda LEIGH-SHARPE, but the size of the trunk and cephalothorax ... -
Comparison of walleye pollock target strength estimates determined from in situ measurements and calculations based on swimbladder form
(Journal article; Peer reviewed, 1988)The target strength of walleye pollock (Theragra chalcogramma) at 38 kHz has been determined in each of two ways: (1) in situ measurement with dual-beam and split-beam echo sounders, and (2) theoretical calculation based ... -

Observations of cod reaction to trawling noise
(Working paper, 1988-04)Observations made from a stationary echo sounder, passed by a trawling vessel, clearly demonstrate the flight reaction of cod as a response to the noise from the vessel. Horizontal dispersal and downward swimming has been ... -
The GEEP Workshop: organic chemical analyses
(Journal article; Peer reviewed, 1988-06-30)For the GEEP Workshop, gas chromatographic/mass spectrometric (GUMS) analyses of selected 2- to 5-ring aromatic hydrocarbons were performed for water, sediments, mussels Mytilus edulis and crabs Carcinus maenas in the ... -
