Ecological consequences of exploration drilling on coral reefs in the Træna Deep
(Fisken og havet, Research report, 2007)Coral reefs, skeleton samples and bottom sediments in the vicinity of the hydrocarbon exploration test well in the Træna Deep have been studied to assess the ecological effects and "health status" of Lophelia coral reefs. ... -
Ecological investigations in the Barents Sea, August 1985. Report from Pro Mare-cruise no. 5
(Rapport/Notat Fysisk oseanografi;FO 8605, Working paper, 1986-01-31)Between 29 July and 19 August 1985, the R/V "G.O.Sars" carried out investigations in the northern Barents Sea. The cruise was organized by the Institute of Marine Research (IMR). The main purpose was to carry out ... -

Effect from the king- and snow crab on Barents Sea benthos. Results and conclusions from the Norwegian-Russian Workshop in Tromsø 2010
(Fisken og havet;8-2013, Research report, 2013)The king crab move further out in the sea in Russian waters compared to the Norwegian waters. This might have important implications on the distribution of feeding pressure and impact of crabs on benthic communities ... -
The effect of fishing on size composition and sex ratio of offshore lobster stocks
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)The lobster fishery in the offshore waters of southern New England is in the early stages of development. The assumption that canyon fishing grounds closest to shore are the most heavily fished was supported by a lower ... -

Effects of hydrocarbons on growth and 14^C-uptake by Thalassiosira psudonana (Bacillariophyceae). In: Flødevigen rapportserie no 2, 1990
(Flødevigen rapportserie, Research report, 1990)Exponentially growing cultures of Thalassiosira pseudonana were exposed to different concentrations of benzene, naphthalene and decane. The acute effects of algal growth were different for increasing concentrations of ... -
Effects of insufficient vertical resolution in a 3d coastal ocean model
(Fisken og havet, Research report, 1999)The consequences of not resolving vertical gradients (of velocity or density) in a three- dimensional numerical model are investigated. The results show that the effects of insufficient vertical resolution are significant ... -
Effects of ocean thermal structure on fish finding with sonar
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)1. The width of the sound beam trapped in the surface channel depends, besides on MLD and INGRAD, also on SST. The latter relation is brought about by nonlinearity in the sound speed dependence on temperature and depth ... -
