Can predator avoidance explain varying overwintering depth of Calanus in different oceanic water masses?
(Journal article; Peer reviewed, 1999-04-15)Distributions of overwintering Calanus spp. in the upper 1000 m in the Norwegian and Greenland Seas were studied in relation to hydrography, invertebrate predators and acoustic scattering layers (38 kHz). C, finmarchicus ... -
Changes in the Norwegian Sea deep water
(ICES CM Documents;1996/O:11, Working paper, 1996)This paper deals with observed changes in the Norwegian Sea Deep Water (NSDW) after the cessation of bottom water formation in the Greenland Sea. Current measurements indicate that the deep water flow from the Greenland ... -
Climatic variability in the Skagerrak and coastal waters of Norway
(Journal article; Peer reviewed, 2011-12-18)The Institute of Marine Research in Norway collects marine data from all national waters. Data are primarily collected from vessels, but observation buoys, manual measurements, and oceanographic gliders are also used. The ... -
Combining hydrographical particles-tracking models with spatial analyses to evaluate spatial dynamics of cod larvae and 0-group in the Barents Sea
(ICES CM Documents;2009/C:06, Working paper, 2009)Recruitment ecology of cod has been an important focus within the framework of GLOBEC. A large part of this work focused on understanding the spatiotemporal component of cod populations. For the early pelagic life stages, ... -
Complete acoustic recording of water column scatters and sea bed characteristics.

Current measurements between the central and great banks in the Barents Sea
(Fisken og havet, Research report, 1994)The report sumarizes the results from current measurements carried out between the Central and Great Banks in the Barents Sea. The moorings were deployed in mid September 1991 and were recovered more than one year later. ... -
Demersal fish on the continental slope off Norway
(ICES CM documents;1975/F:29, Working paper, 1975)Investigations on distribution and abundance of demersal fish in 400-1000 m depth were carried out in three selected areas off Norway in July-August 1974. Based on catches in 48 hauls by bottom trawl and 3 long-line settings ... -
The design and use of a profiling instrument for measuring and recording physical variables in the sea
(ICES CM Documents;1977/C:22, Working paper, 1977)The paper describes a measuring system for profiling of the upper few hundred meters of the sea. The system consists of a recording instrument and a readout unit. The recording instrument has sensors for current, direction, ... -
Dissolved oxygen in contrasting estuaries of the Bay of Biscay: effects of temperature, river discharge and chlorophyll a
(Journal article; Peer reviewed, 2010-11-18)The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the ... -
Effects of climate and stocks interactions on the yield of north-east arctic cod. Results from multispecies model run
(ICES CM documents, Working paper, 2000)A conceptual climate dependent multispecies model for stock interactions and harvesting of herring, capelin and cod in the Norwegian Sea-Barents Sea region has been developed. The concept presupposes that good recruitment ... -
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 ... -
Feeding ecology of Atlantic mackerel (Scomber scombrus) in the Norwegian Sea
(ICES CM documents, Working paper, 2006)Previous studies on Atlantic mackerel (Scomber scombrus) feeding during the highly migratory summer period are scarce. In this study we present detailed diet analyses and investigations of prey selection for Atlantic ... -
First report on the working group on pollution baseline and monitoring studies in the Oslo commission and ICNAF areas : Charlottenlund, 7 - 9 January 1975

Fjordbassengene i ytre Oslofjord. Oksygenforbruk, organisk belastning og vannutskifting. (Fjord basins of the Ytre Oslofjord, oxygen consumption, organic load and water exchange)
(Fisken og havet, Research report, 1996)The major yearly inflow to the Ytre Osloford basins normally occure in the period March - July. In 1995 a stagnation period lastedfrom June until NovemberiDecember and an inflow periodfrom December to May 1996. The mean ... -
Flomvann fra Glomma og miljøforholdene i Skagerrak sommeren 1995. (The Glomma flood and the environmental conditions in the Skagerrak in the summer 1995)
(Fisken og havet, Research report, 1996)The fresh-water influence from the flood in June, 1995 to the eastern Skagerrak created an unusual and very fresh surface layer with a strong halocline. The surface water with extremely low salinities was detected all ... -
Formation of nutrient rich bottom water in the eastern parth of the Barents Sea
(ICES CM Documents;1997/R:1, Working paper, 1997)During yearly routine observations of hydrography, nutrients and plankton in the Barents Sea we have observed a distinct anomaly in the distribution of the nutrients silicate and nitrate in near bottom water in an area ... -
Gelatinous zooplankton on the Mid-Atlantic Ridge, Distribution patterns of trawl-collected planktonic cnidarians
(ICES CM documents;2008/C:21, Working paper, 2008)The Mid-Atlantic Ridge (MAR) between 40˚N (Azores) and 63˚N (Iceland) is the largest topographic feature in the North Atlantic Ocean. However, the fauna and ecological significance of mid-ocean ridges has remained poorly ... -
A general system for logging information from instruments in the sea.
