Detection and counting of individual free-swimming krill using a 2MHz scanning sonar
(ICES CM Documents;1992/L:18, Working paper, 1992)The euphausiid crustacean Meganyctiphanes norvegica (M. Sars) have been detected and counted in the scanning section of a 2 MHz scanning sonar beam up to 3 meters from the sonar head. The tests completes a pilot investigation ... -

Diets of hooded seals in coastal and drift ice waters along the east coast of Greenland
(ICES CM documents, Working paper, 2005)To provide data on the feeding habits of hooded (Cystophora cristata) seals in the Greenland Sea, seals were collected for scientific purposes on expeditions with R/V”Jan Mayen”, conducted in the pack ice belt east of ... -
A discussion on the value of the estimation of polychlorinated biphenyls (PCB`s) in environmental samples from packed column gas-liquid chromatographic data.
(ICES CM Documents;1980/E:35, Working paper, 1980) -
The distribution of redfish larvae in Norwegian coastal and offshore waters during the years 1948-58
(ICES CM Documents;1959/9, Working paper, 1959) -
Distribution, abundance and trends in abundance of fin and humpback whales in the North Atlantic
(ICES CM documents, Working paper, 2005)The North Atlantic Sightings Surveys (NASS) are a series of international cetacean line transect surveys, including participation from the Faroe Islands, Iceland, Norway and Spain, that have been conducted in 1987, 1989, ... -
Do capelin larvae deposit daily increments in their otoliths?
(ICES CM documents, Working paper, 2004)Analysis of increment formation in larval fish otoliths has provided valuable information about growth, transport and mortality processes of larvae in wild stocks, but the technique has not been widely used on capelin ... -
Effect of turbulence and different types of fertilizers on phytoplankton and oyster larvae (Ostrea edulis) in mesocosms
(ICES CM Documents;1986/K:41, Working paper, 1986)Different types of inorganic fertilizers were added to five cubic metres plastic bags. Different turbulent regimes were established in the bags. The effects of these manipulations on nutrient salts, chlorophyll a, ... -
Effects of climate on marine ecosystem
(ICES CM Documents;2003/O:7, Working paper, 2003)The spawning areas of the Arcto-Norwegian cod are located along the coast of mid and northern Norway, particulary in the Lofoten where up to 70% of the spawning occurs from mid March to early May. The larvae are carried ... -
Effects of organic waste from marine fish farms on the seabottom beneath the cages
(ICES CM Documents;1990/F:34, Working paper, 1990)Seven fish farms and a control station were investigated four times during one year. The farms represented a gradient of increasing accumulation of organic waste on the sea bottom. The thickness and the organic content ... -
The Ekofisk brave blow out : Compiled Norwegian Contributions
(ICES CM Documents;1977/E:55, Working paper, 1977) -
Environmental effects of marine Norwegian fish farms
(ICES CM Documents;1985/F:37, Working paper, 1985)Sedimentation rates under fish farms may be very high, and high levels of fish stock may lead to harmful accumulation rates of the nutrient salt ammonia. The environmental effects of the organic load range from minor ... -
Enzyme polymorphism expressed in newly hatched cod larvae and genetic analysis of larvae exposed to hydrocarbons.
(ICES CM Documents;1980/F:22, Working paper, 1980)Cod eggs and larvae, at different stage of development, have been analyzed by starch gel electrophoresis. Four common enzymes (phosphoglucose isomerase, phosphoglucose mutase, isocitrate dehydrogenase and lactate ... -

Episodic formation of intermediate water along the Greenland Sea Arctic Front
(ICES CM Documents;1995/Mini:6, Working paper, 1995)During CTD and plankton surveys in the Nordic Seas in November 1991 - 1994, a CTD section has been worked across the Arctic Front between the Lofoten and Greenland Basins. Along this front Isopycnic surfaces slope down ... -
Estimation of harp seal pup production in the Greenland Sea using spatial analysis on aerial survey data
(ICES CM documents, Working paper, 2005)From 14 March to 6 April 2002 aerial surveys were carried out in the Greenland Sea packice to assess the pup production of the Greenland Sea population of harp seals Pagophilus groenlandicus. One xed-wing twin-engined ... -

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 ... -
