Age dependent sensitivity of oil on fish larvae, used in assessment of potential oil pollution damages on fish resources
Føyn, Lars; Serigstad, Bjørn (ICES CM Documents;1987/E:12, Working paper, 1987)Oil exploration in Norwegian waters will probably be extended further north into the Barents Sea. The Barents Sea is the nursery ground for important fish stocks spawning outside the norwegian coast, north of 62°N. Fish ... -
Are nutrients and nutrient related parameters suitable in trend monitoring of antropogenic influence?
Føyn, Lars (ICES CM Documents;1988/E:20, Working paper, 1988)Examples of observations of nutrients from the North Sea, Skagerrak, Kattegat and some Norwegian fjords are presented. The paper discuss the usefullness of such data in trend monitoring and how such data can be used and ... -
Assessment of potential oil pollution damages on fish resources. Some examples from the area outside mid-Norway
Føyn, Lars; Bjørke, Herman (ICES CM Documents;1987/E:13, Working paper, 1987)Detailed mapping of fish eggs and larvae both in space and time is essential knowledge when realistic assessments of oil pollution damages to the fish resources are established. The text explain with some examples our ... -
Distribution and sedimentation of radionuclides in the Barents Sea
Føyn, Lars; Sværen, Ingrid (ICES CM Documents;1995/Mini:11, Working paper, 1995)Analysis of sediment samples for cesium-137 from a wide range of positions have demonstrated an uneven distribution. The causes, pathways and the possible origin of the radionuclide are discussed. The importance of ... -
Experimental dumping of waste ferrosulfate (copperas) into the Skagerrak
Berge, Grim; Føyn, Lars; Ljøen, Rikard; Palmork, Karsten H. (ICES CM Documents;1971/E:32, Working paper, 1971) -
Formation of nutrient rich bottom water in the eastern parth of the Barents Sea
Føyn, Lars; Hagebø, Magnar; Rey, Francisco; Seglem, Kjell (ICES CM Documents;1997/R:1, Working paper, 1997)During yearly routine observations of hydrography, nutrients and plankton in the Barents Sea we have observed a distinct anomaly in the distribution of the nutrients silicate and nitrate in near bottom water in an area ... -
How can a potential oil pollution affect the recruitment to fish stocks?
Føyn, Lars; Serigstad, Bjørn (ICES CM Documents;1989/Mini:5, Working paper, 1989)Eggs, larvae and the larvae's first search for food are the most critical stages in a fish life, both to threats from natural causes and pollution. Based on experimental studies of several species of fish eggs, larvae ... -
Oil exploration in new offshore fields. Fish larvae as the critical component in the assessment of potential consequenses for the fish resources
Føyn, Lars; Serigstad, Bjørn (ICES CM Documents;1988/E:18, Working paper, 1988)The effects of oil and other pollutants on fish larvae are depending both on species and age/weight/length of the larvae. Critical factors in an assessment of consequenses of oil activities on fish resources are both ... -
Radioactive contamination in the Barents Sea, past and present status, uptake of radinuclides in fish and its impact on fisheries
Føyn, Lars (ICES CM Documents;1994/E:16, Working paper, 1994)During the atmospheric nuclear bomb test at the end of the fifties and in the beginning of the sixties the Institute of Marine Research, IMR, monitored the radioactive contamination in commercial landed fish from the ... -
Report on a cruise by the R/V "G. O. Sars" to West Africa 23 October - 15 December 1972
Østvedt, Ole Johan; Blindheim, Johan; Føyn, Lars; Berge, Grim; Smedstad, Odd M.; Vestnes, Gudmund (ICES CM Documents;1973/J:23, Working paper, 1973) -
SKAGEX 1990. Preliminary results from the nutrient intercalibration
Føyn, Lars (ICES CM Documents;1990/C:44, Working paper, 1990)An important part of SKAGEX 1990 was the nutrient intercalibration, which was performed to simulate ordinary work at sea. 44 water samples of 0,5 liter were delivered to each of the 13 participating research vessels in ... -
Stimulated growth and safeguarding of the ICES oceanographic data bank
Carlberg, Stig R.; Føyn, Lars (ICES CM Documents;1988/C:16, Working paper, 1988)During a number of years there has been a consent to build up and increase the ICES oceanographic data base to the benefit of the member countries. In parallel to this there has been an increasing demand for ICES to ... -

Føyn, Lars; Bjørke, Herman (ICES CM Documents;1986/E:34, Working paper, 1986) -
The effects of oil-base drilling mud and crude oil on demersal fish eggs
Serigstad, Bjørn; Sværen, Ingrid; Føyn, Lars (ICES CM Documents;1988/E:19, Working paper, 1988)The Norwegian spring spawning herring and the Barents Sea capelin both with demersal eggs, spawn in relative small and concentrated areas on the Norwegian continental shelf. Besides potential impact on the fish resources ... -
