Estimates of stock size of cod, haddock, redfish and greenland halibut in the Barents Sea and the Svalbard area, autumn 1987
(ICES CM Documents;1988/G:44, Working paper, 1988)Combined acoustic and bottom trawl survey for cod and haddock were carried out in the Svalbard area together with an acoustic survey in the Barents Sea in autumn 1987. The abundance index in numbers of cod continued ... -
Estimates of stock size of northeast Arctic cod and haddock, "Sebastes mentella" and "Sebastes marinus" from survey data, winter 1988
(ICES CM Documents;1988/G:43, Working paper, 1988)An acoustic survey and a bottom trawl survey for cod and haddock were carried out in the Barents Sea during the winter 1988. The fish still had the westerly distribution established in the previous year, but the echo ... -
Estimation of predation mortalities on capelin using a cod - capelin model for the Barents Sea
(ICES CM Documents;1990/H:16, Working paper, 1990)The Barents Sea capelin stock collapsed during the period 1983-1986. One of the main factors causing the collapse was a rapid increase in consumption of capelin by cod. Based on measurements of stomach evacuation rates ... -
Estimation of unreported catch in a commercial trawl fishery
(ICES CM Documents;1991/D:12, Working paper, 1991)The Institute of Marine Research (IMR), Bergen, has carried out combined bottom trawl and acoustic surveys for cod in the Barents Sea since 1981. Commercial statistics are collected routinely for this area through the ... -
Et digitalt temperaturatlas for Norskehavet
(Fisken og havet, Research report, 2009)A digital temperature archive for the Norwegian Sea compiled from 59496 temperature profiles is presented. It consists of interpolated temperature fields for the quarters January-March, April-June, July-September, and ... -
Eutrophication issues attacked by a numerical model of the North Sea/Skagerrak
(ICES CM documents, Working paper, 2003)Several issues of eutrophication in the North Sea and Skagerrak have been attacked using a three dimensional ecological model, NORWECOM. The focus have been on two different years, 2000 and 2001, their characteristics ... -
Eutrophication Scenaria from Reduced Nutrient Loads to the North Sea
(ICES CM documents, Working paper, 2003)The environmental effects of river nutrient loads to the North Sea have been investigated using a numerical biophysical model, NORWECOM, to perform different reduction scenarios. The simulations demonstrate that the river ... -
Evaluation of a Nordic Seas 4 km numerical ocean model hindcast archive (SVIM), 1960-2011
(Fisken og Havet;7-2013, Research report, 2013) -
Evaluation of the North-East Arctic saithe (Pollachius virens) acoustic survey
(ICES CM Documents;1997/Y:20, Working paper, 1997)Since 1985 an acoustic survey specially designed for saithe has annually been conducted in October-November by the Institute of Marine Research (IMR) on the Norwegian near coastal banks. Since 1992 the survey has covered ... -
Evaluation of the Norwegian shrimp surveys conducted in the Barents Sea and the Svalbard area 1980- 1997
(ICES CM Documents;1997/Y:7, Working paper, 1997)Trawl surveys for shrimp (Pandalus borealis) have been conducted annually in the Barents Sea and the Svalbard area since 1980 by Norwegian research institutes. The surveys have been conducted in the period April to ... -
Evidence for effects on the North Sea ecosystem due to varying oceanic inflow over the last 100 years
(ICES CM Documents;2002/Q:8, Working paper, 2002)Oceanic inflow is estimated to contribute more than 90% of the nutrient input into the North Sea (NSTF, 1993). Variability in the volume, chemical properties, biological content and source of the inflowing water is thus ... -
Experimental Oceanography in the Norwegian Sea
(ICES CM Documents;1956/60, Working paper, 1956) -
Explotation and state of stock

Extinction cross section of herring: New measurements and speculation
(ICES CM Documents;1994/(B+D+G+H):2, Working paper, 1994)Acoustic abundance estimation of dense, vertically extended aggregations of fish requires knowledge of the extinction cross section. An established method based on a comparison of the area backscattering coefficients ... -
Factors affecting the distribution of wrasses in a fjord system: analysis by generalised linear models
(ICES CM Documents;2000/N:31, Working paper, 2000)Background: Generalised linear models (GLMs, see McCullagh & Nelder 1989) form a modern, flexible and unified approach to statistical modelling. GLMs are of particular value to the analysis of data from ecological surveys, ... -
Fecundity of sprat from the Norwegian coast

Feeding and migration of Norwegian spring spawning herring in the Norwegian Sea
(ICES CM Documents;1994/R:9, Working paper, 1994)After spawning on the shelf off Møre, Western Norway, the spawning stock of Norwegian spring spawning herring migrates to the Norwegian Sea for feeding. Simultaneously, the adolescent part of the stock leaves the wintering ... -
Feeding conditions of north-east Arctic (Arcto-Norwegian) cod larvae compared to the Rothschild-Osborn theory on small-scale turbulence and plankton contact rates
