Ocean pathways in the Arctic
(ICES CM Documents;1997/R:8, Working paper, 1997)Introduction: The Arctic Monitoring and Assessment Programme (AMAP), established in 1991, was given the responsibility to monitor the levels and assess the effects of selected anthropogenic pollutants in all compartments ... -
Oil exploration in new offshore fields. Fish larvae as the critical component in the assessment of potential consequenses for the fish resources
(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 ... -
Oil production structures in the North Sea as fish aggregating devices
(ICES CM documents, Working paper, 1998)The paper deals with a study aimed at investigating whether underwater structures from decommissioned oil platforms in the North Sea can be used as artificial fish reefs or protection habitats for fish. The experimental ... -
Oil-tainting of fish, a laboratory test on salmon and saithe
(ICES CM Documents;1976/E:33, Working paper, 1976) -
Old and new perspectives on zooplankton and vertical particle flux
(ICES CM Documents;1996/O:10, Working paper, 1996)Our understanding of the relationships between zooplankton and vertical flux of particles in the North Atlantic has matured over the last half century. Evolving from the simple concept of 11 grazing inhibits sedimentation", ... -
On acoustic identification, sizing and abundance estimation of fish
(ICES CM documents, Working paper, 1970) -
On acoustic multi-frequency species identification and separation of Atlantic mackerel, Norwegian spring spawn herring and Norway pout.
(ICES CM documents, Working paper, 2004)The accuracy of the multi-frequency species identification and separation algorithms may be significantly improved when the detailed acoustic scattering characteristics of the fish are known, including its expected variability ... -
On controlled discharges of oil hydrocarbons from the Ekofisk field terminal platform
(ICES CM Documents;1976/E:32, Working paper, 1976) -
On fecundity of North Sea mackerel (Scomber scombrus)
(ICES CM Documents;1980/H:47, Working paper, 1980)This paper presents a preliminary analysis of the fecundity-length relationship of the North Sea mackerel. The relationship was compared to that of the Western mackerel stock (LOCKWOOD,1978) by an analysis of covariance ... -
On multiple scattering in fisheries acoustics
(ICES CM Documents;1982/B:38, Working paper, 1982) -
On subjectivity in the judging of acoustic records; comparison of degree of homogenity in allocation of echo values by different teams
(ICES CM Documents;1993/B:21, Working paper, 1993)On four fish abundance estimation surveys in the Barents Sea, january-february 1993, the acoustic records were judged by two independent teams. We have analyzed the degree of homogenity in allocation of echo values to ... -
On the abnormal hydrographic conditions in the European Arctic durig the 1970`s
(ICES CM Documents;1984/GEN:3, Working paper, 1984) -
On the application of the echointegration method
(ICES CM documents;1983/B:19, Working paper, 1983)The echo integration method used by the Institute of Marine Research is described. The model which are used to convert acoustic abundance indices into fish densities using length and species dependant conversion factors, ... -
On the depth dependence of fish target strength
(ICES CM Documents;1997/FF:7, Working paper, 1997)Data on the depth dependence of the target strength of live kokanee (Oncorhynchus nerka), a physostome, at 50 kHz (Mukai, T., and Iida, K., ICES J. mar. Sci., 53: 245-248 (1996)) have been reexamined. In the cited study, ... -

On the formation of the first winter zone in blue whiting otoliths.
(ICES CM Documents;1979/H:7, Working paper, 1979)Otolithes of juvenile blue whiting when recruiting to the industrial fishery in the Norwegian Deep in early autumn (August-October 1970-72) could be divided into two groups, without or with a very insignificant hyaline ... -
On the frequency dependence of target strength of mature herring
(ICES CM Documents;1992/B:10, Working paper, 1992)Mature herring (Clupea harengus), hibernating in Ofotfjord in December 1991, was measured simultaneously at each of three frequencies: 18, 38, and 120 kHz. Measurements of the mean volume backscattering coefficient were ... -
