Heat content in the Norwegian Sea, 1995–2010
(Journal article; Peer reviewed, 2012-02-26)Spatio-temporal hydrographic data from the Nordic Seas during spring over the period 1995–2010 were investigated in terms of the relative heat content (RHC) above the density surface σt = 27.9, chosen to capture the changes ... -

How does stochasticity affect evolutionary regime shifts in age and size at maturation?
(ICES CM documents, Working paper, 2006)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. We have shown ... -
How variable is the fecundity within and between cod stocks?
(ICES CM documents, Working paper, 2005)Stock reproductive potential is determined by the number of fish at age, sex ratio, proportion of mature female at age and fecundity. Fecundity data, which are fundamental in estimating egg production are not collected ... -
Hva bestemmer egenskaper og økologisk funksjon i ålegrasenger?
(Research report, 2014)Juni 2014 ble 27 ålegrasenger i Aust-Agder undersøkt for å analysere hvilke miljøfaktorer som bestemmer egenskaper som tetthet og høyde til ålegrasplanten i engene, og om enger med tett ålegrasvegetasjon er leveområde for ... -
Hva skjer i havet? Økosystemet i Norskehavet under lupen

Hvor allsidig er bardehvalenes kosthold?
(Ottar;nr. 280 - 2010, Journal article, 2010)Bardehvaler er store og tallrike og viktige predatorer i Barentshavet. Hvor beiter de, hva beiter de på og hva gjør de når bestander av byttedyr kollapser? For å lære mer om dette observerte vi bardehvaler under ... -

ICES working group on pollution baseline and monitoring studies in the Oslo commission and ICNAF areas : Report of the sub-group on the feasibility of effects monitoring
(ICES CM Documents;1976/E:44, Working paper, 1976)This report first discusses selected recent literature on the effects of pollutants on marine organisms under six headings - biochemical, morphological, physiological, behavioural, population/community and genetic, and ... -
ICES Workshop on Time Series Data relevant to Eutrophication Ecological Quality Objectives [WKEUT] [11–14 September Tisvildeleje, Denmark]

Identifying particularly valuable and vulnerable areas: a key tool for the integrated management plans for the Barents Sea and Norwegian Sea.
(ICES CM documents;2008/E:14, Working paper, 2008)In 2006 Norway implemented an integrated and ecosystem-based management plan for the Barents Sea, and is currently developing a similar plan for the Norwegian sea. Norway aims to have such plans for all sea areas under ... -
Impact of biogeochemical processes and environmental factors on the calcium carbonate saturation state in the Circumpolar Flaw Lead in the Amundsen Gulf, Arctic Ocean
(Journal article; Peer reviewed, 2011-12-30)We report on measurements across an annual cycle of carbon dioxide system parameters in the polar mixed layer (PML) of the circumpolar flaw lead in the Amundsen Gulf, Arctic Ocean. From these and other properties (nitrate, ... -
The impacts of different management strategies and environmental forcing in ecological communities
(Journal article; Peer reviewed, 2006-07-05)Understanding the effects of population management on the community a target species belongs to is of key importance for successful management. It is known that the removal or extinction of a single species in a community ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
(Journal article; Peer reviewed, 2009-07-31)Worldwide depletion of fish stocks has led fisheries managers to become increasingly concerned about rebuilding and recovery planning. To succeed, factors affecting recovery dynamics need to be understood, including the ... -
"Import" av fiskeyngel til norske farvann [HELP 35]
(help;1990 nr. 35, Research report, 1990)Fordelingen av fiskeyngel i norske farvann om våren og sommeren indikerer sterkt at noe av denne yngelen er "importert" fra gytefelt utenfor det økosystemet som omfatter norskekysten og Barentshavet. Dette gjelder for ... -

In/out-flow of coastal water in Vestfjorden
(ICES CM Documents;1978/C:51, Working paper, 1978)Hydrographic sections in Vestfjorden, Northern Norway, during winter 1977 showed strong horizontal temperature gradients on the west side of the fjord indicating an outflow of cold coastal water. Analysis of sea thermograph ... -
Including climate into the assessment of future fish recruitment, using multiple regression models.
(ICES CM documents, Working paper, 2005)Climate variability has generally not been included in the assessment of fish stocks in the Barents Sea and Norwegian Sea. However, in recent years there has been a focus on implementing climate variability in the assessment ...
