Polarfrontens fysiske beskaffenhet og biologiske implikasjoner – en verdi- og sårbarhetsvurdering av polarfronten i Barentshavet
(Fisken og Havet;8-2018, Research report, 2018)Polarfronten er definert som skillet i Barentshavet mellom relativt varme og salte vannmasser av atlantisk opprinnelse og kaldere og ferskere vannmasser av arktisk opprinnelse. På grunn av de fysiske særtrekkene og ... -
Polartorsk
(Havets ressurser og miljø, Chapter, 2007)The stock of polar cod in the Barents Sea is quite large, probably between 1.5 and 2 million tonnes. This resource has not been exploited to any noticeable degree since the early 1970s. The distribution area and the ... -
Polartorskundersøkelser i Barentshavet somrene 1970 - 1972
(Fisken og havet, Research report, 1973)In 1970, 1971 and 1972 cruises were conducted in the Barents Sea during May and June. The main aim was to find fishable concentrations of Polar cod and to guide the Norwegian vessels fishing for this species. In 1970 ... -

Polymorphism of serum transferrin in cod
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1966)Sera from 682 cod from six different localities along the Norwegian coast and in the Barents Sea have been investigated by starch/agar gel electrophoresis. Eleven different patterns composed by five molecular types have ... -
Population genetic studies in cod (Gadus morhua L.) by means of the haemoglobin polymorphism; observations in a Norwegian coastal population
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1984)A total of 1205 immature and mature cod (Gadus morhua L.) of both sexes, caught during 1976-1981 in the Trondheimsfjord, Norway, were investigated in a population-genetic study by means of the polymorphic haemoglobin ... -
Populations of the deep-sea shrimp (Pandalus borealis Krøyer) in the Barents Sea
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1983)Three populations of P. borealis were identified in the open part of the Barents Sea. In the (4-1) population the females spawn each year and sex-change occurs 4 years old. This population was found in the soutwestern ... -

Potential implications on the pelagic fish and zooplankton community of artificially induced deep-water releases of oil and gas during DeepSpill_2000 – an innovative acoustic approach.
(Fisken og havet;14-2001, Research report, 2001-12-15)During the DeepSpill_2000 field experiment (Johansen et al., 2001) oil and gas were artificially released on several occasions from a water depth of 844 meters at the Helland-Hansen site in the Norwegian sea. Prior to and ... -
Power-budget and echo-integrator equations for fish abundance estimation
(Fisken og Havet;10-2013, Research report, 2013-12-31)For abundance estimation and species identification on fisheries acoustic surveys, control with temperature and finite amplitude effects in the sea demands the calibration factor C of the conventional echo-integrator ... -
