Norwegian investigations in 1984 -1985 on juvenile herring
(ICES CM Documents;1985/H:53, Working paper, 1985)This paper describes tlte Norwegian investigations on juvenile herring (0-, I- and II-group) of the Norwegian spring spawning stock. The investigations were carried out in Norwegian coastal areas and in the Barents Sea ... -
Norwegian investigations on Gonatus fabricii (Lichtenstein)
(ICES CM Documents;1995/K:12, Working paper, 1995)By far the majority of the investigated Gonatus fabricii were caught as bycatch by pelagic trawls fishing in the upper 60 m. Sampling took place in April/May, June/July and August/September in the period 1978- 1991. The ... -
Norwegian investigations on the deep sea shrimp (Pandalus borealis) in the Barents Sea in April - May 1984 and in the Spitsbergen area in July -August 1984
(ICES CM Documents;1984/K:21, Working paper, 1984)This report discribes the results from a stratified bottom trawl survey with R/V "Michael Sars" in April - May 1984 in the Barents Sea between 71°30'N - 76°00'N and between 16°30'e 35°30 'E. The report also decribes the ... -
Norwegian sprat investigation in the North Sea in later years
(ICES CM Documents;1984/H:37, Working paper, 1984)The variation in abundance and distribution of sprat during November 1979, January 1980, 1981 and 1982 is studied in relation to environmental factors. The main abundance of sprat was observed in waters with salinity ... -
An object-based approach to integration of software to support management and reporting of marine ecosystem survey data
(ICES CM documents, Working paper, 2006)An object-based software to support distributed databases and data reporting from combined fisheries and environmental surveys is presented. The key abstraction of this system is expressed as a generic station (data) object. ... -
Observation of fish behaviour, density and distribution around a surveying vessel by means of a deployable echo sounder system
(ICES CM Documents;1999/J:9, Working paper, 1999)Detailed acoustic observations of fish behaviour, distribution and density in the trawl area are necessary in order to establish quantitative relationships between trawl samples and fish density. Acoustic observation ... -
Occurence of blue whiting in trawl catches during surveys from Portugal to Faroe Islands, 1979- 1995
(ICES CM Documents;1996/S:30, Working paper, 1996)Historical data on blue whiting (Micromesistius poutassou) from survey trawl stations of 7 countries, have been congregated and prepared into special files, together with corresponding temperature and salinity observations. ... -
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 ... -
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 the abnormal hydrographic conditions in the European Arctic durig the 1970`s
(ICES CM Documents;1984/GEN:3, Working paper, 1984) -
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 mechanisms behind salinity anomaly signals of the northern North Atlantic
(ICES CM documents, Working paper, 2001) -
On the site-specific role of the central Norwegian shelf for the recruitmen strategy of the Norwegian spring spawning herring
(ICES CM documents, Working paper, 1998) -
On the temperature variation in the bottom water of the northern North Sea
(ICES CM Documents;1971/C:33, Working paper, 1971) -
Operating experiences with a modular instrumentation system for measuring current speed, direction and temperature

Optimization of purse seines by large meshed sections and low lead weight. Theoretical considerations, sinking speed measurements and fishing trials.
(ICES CM Documents;1988/B:25, Working paper, 1988)Theoretical considerations on material requirements and sinking speed by use of different mesh size and lead weight in purse seines are outlined. Measurements confirmed that the sinking speed varied with mesh size and ... -
Optimum size of sampling unit for estimating the density of marine populations
(ICES CM Documents;1989/D:22, Working paper, 1989)Data from several trawling experiments and from some scallop dredge surveys indicate that, within limits, a srnaller sampling unit can be more effective than a larger unit for marine abundance surveys. Taking into account ...
