Coastal water darkening and implications for mesopelagic regime shifts in Norwegian fjords
(Journal article; Peer reviewed, 2009-07-28)The light regime of the water column has a strong structuring effect on aquatic food webs and it has been previously hypothesized that coastal water darkening has increased the success of tactile predators relative to ... -
A comparison of variability and bias when ageing Northeastern Atlantic minke whales (Balaenoptera acutorostrata) by counting growth layer groups in the mandible and bulla tympanica
(ICES CM documents, Working paper, 2001)The age of 43 minke whales (Balaenoptera acutorostrata) was estimated by counting growth layer groups (GLGs) GLGs in 500um thick haemotoxylin stained transverse sections of left and right mandible. The same whales were ... -
Concentration of polychlorinated biphenyls in different tissues of cultured rainbow trout, (Salmo gairdneri)
(ICES CM Documents;1987/E:31, Working paper, 1987)Trunk muscle, ventral muscle, visceral fat and liver from cultured rainbow trout (Salmo gairdner) were analysed for PCB congeners. The congeners quantified were components 52, 49, 44, 101, 118, 138, 187, 183, 128, 180, ... -
Conservation, Spillover and Gene Flow within a Network of Northern European Marine Protected Areas
(Journal article; Peer reviewed, 2013-09-06)To ensure that marine protected areas (MPAs) benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design ... -
Contaminants in the Barents Sea ecosystem
(ICES CM Documents;1995/Mini:9, Working paper, 1995)A baseline study of contaminants in fish and sediments from the Barents Sea was carried out by Institute of Marine Research (IMR) as a part of the Arctic Monitoring and Assessment Programme, AMAP. Sediment samples from ... -

Demersal Fish Assemblages and Spatial Diversity Patterns in the Arctic-Atlantic Transition Zone in the Barents Sea
(Journal article; Peer reviewed, 2012-04-17)Direct and indirect effects of global warming are expected to be pronounced and fast in the Arctic, impacting terrestrial, freshwater and marine ecosystems. The Barents Sea is a high latitude shelf Sea and a boundary area ... -
Density in sub-arctic zooplankton
(ICES CM documents, Working paper, 1985)Seasonal variations in specific density were measured for Thysanoessa inermis, Thysanoessa raschii, Meganyctiphanes norvegica, Calanus finmarchicus and Calanus hyperboreus. The density of a 20 mm T. inermis was lowest in ... -
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 ... -
Differential processing of yolk proteins during oocyte hydration in marine fishes (Labridae) that spawn benthic and pelagic eggs
(Journal article; Peer reviewed, 2002-07-18)The yolk proteins and free amino acids (FAA) were investigated during oocyte maturation in 4 species of Labridae with either benthic or pelagic eggs. Benthic eggs and oocytes of both types had a small FAA pool dominated ... -
