Sublethal effects of the water-soluble fraction of Ekofisk crude oil on the early larval stages of cod (Gadus morhua L.)
(ICES CM Documents;1981/E:52, Working paper, 1981) -
Swell as a turbulence source in shallow water
(ICES CM documents, Working paper, 2005)Two field investigations in an exposed shallow area outside Lofoten, western Norway, were conducted in 1995 and 1996. Direct measurements of turbulence were conducted from an underwater tower with acoustic current meters ... -
Swept area variation with depth and its influence on stratified trawl surveys indices on Arcto-Norwegian cod
(ICES CM Documents;1986/D:18, Working paper, 1986)Stratified trawl surveys have been carried out in the Barents Sea and the Svalbard areas since 1981. Based on the assumption of a constant area swept by the trawl during a standard trawl haul at any depth, swept area ... -
Temperature and salinity fluctuations in the Norwegian Sea in relation to wind
(ICES CM Documents;1999/L:3, Working paper, 1999)Hydrographic observations in the Svinøy section and results from the Princeton Ocean Modei are used to investigate the role the wind forcing has on temperature and salinity fluctuations in the Nonvegian Sea. In order to ... -
The activity of alevins of Atlantic salmon and rainbow trout, incubated on different substrates
(ICES CM Documents;1986/F:24, Working paper, 1986)Atlantic salmon (Salmo salar) and rainbow trout (S. gairdneri) eggs were incubated in plexi-glass aquariums. After hatching, alevins were kept in darkness, two groups of each species without substrate, two groups in ... -
The Benguela Niño 1995 observed in Angolan waters
(ICES CM Documents;1995/C:12, Working paper, 1995)During the cruise by R/V ''Dr. Fridtjof Nansen" in February-March 1995, we observed that the upper ocean layers were very warm and brackish. Comparing with a similar cruise performed in 1994, the water temperature was ... -
The bioeconomic consequences of fisheries ]induced adaptive changes
(ICES CM documents;2010/M:02, Working paper, 2010) -
The Chrysochromulina polylepis bloom in the Skagerrak and the Kattegat in May - June 1988: Environmental conditions, possible causes and effects
(ICES CM Documents;1989/L:18, Working paper, 1989) -
The detection of larval fish food particles by an in situ particle counter, and monitoring of the particle density and distribution in first feeding areas.
(ICES CM Documents;1981/L:15, Working paper, 1981) -
The effect of carotenoids on the development of roe and on growth rate of Atlantic salmon fry
(ICES CM Documents;1982/M:12, Working paper, 1982) -
The effects of light on the mortality of different pigmented atlantic salmon (Salmo salar) eggs.
(ICES CM Documents;1981/M:16, Working paper, 1981) -
The effects of oil-base drilling mud and crude oil on demersal fish eggs
(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 ... -
The Jutland Current: Nutrients and physical oceanographic conditions in late autumn 1989
(ICES CM Documents;1990/C:35, Working paper, 1990)Hydrography, currents, nutrients, water transparency, in situ chlorophyll fluorescence and primary production were studied during a cruise with R/V "G.O. Sars" to the west coast of Denmark, Skagerrak and Kattegat from ... -
The potential of the Jutland coastal current as a transporter of nutrients to the Kattegat
(ICES CM Documents;1991/C:34, Working paper, 1991)Annual fluctuations and distributions of nitrate during the 1980s in areas along the Danish west coast and in the northern Kattegat have been examined and compared. Transport of nitrate brought about by the Jutland ... -
The relation between the spatial distribution of early juvenile cod (Gadus morhua L.) and zooplankton biomass in the Barents Sea
(ICES CM Documents;1997/T:32, Working paper, 1997)The year class strength of Arcto-Norwegian cod (Gadus morhua L.) in the Barents Sea is extremely variable. One of the key indicators for a possible strong year class is water temperature since good year classes may be ... -
The use of in situ deployment of live organisms and passive samplers to monitor contaminants in pelagic ecosystems
