Validation and Determination of 25(OH) Vitamin D and 3-Epi25(OH)D3 in Breastmilk and Maternal- and Infant Plasma during Breastfeeding
(Peer reviewed; Journal article, 2020)Vitamin D deficiency in pregnant women and their offspring may result in unfavorable health outcomes for both mother and infant. A 25hydroxyvitamin D (25(OH)D) level of at least 75 nmol/L is recommended by the Endocrine ... -
Validation and reproducibility of a new iodine specific food frequency questionnaire for assessing iodine intake in Norwegian pregnant women
(Journal article; Peer reviewed, 2019)Iodized salt is not mandatory in Norway, and the permitted level of iodine in table salt is low (5 μg/g). Thus, milk and dairy products, fish and eggs are the main dietary sources of iodine in Norway. Mild-to-moderate ... -
Validation and sensitivity study of a Sigma-coordinate ocean model using the Skagex dataset
(ICES CM Documents;1996/C:5, Working paper, 1996)Numerical ocean models are now being applied in numerous oceanographic studies. However, standards and procedures for evaluation of these models are far from established. In this paper the use of data from hydrographical ... -

Validation of a Liquid–Liquid Extraction Method to Study the Temporal Production of D-Series Resolvins by Head Kidney Cells from Atlantic Salmon (Salmon salar) Exposed to Docosahexaenoic Acid
(Peer reviewed; Journal article, 2023)A simple and rapid method for the extraction of D-series resolvins (RvD1, RvD2, RvD3, RvD4, RvD5) released into Leibovitz’s L-15 complete medium by head kidney cells from Atlantic salmon and the further determination of ... -
Validation of age estimation in the Harp seal, Phoca groenlandica, using dentinal annuli
(Journal article; Peer reviewed, 1983)We investigated the validity and accuracy of age estimation in harp seals, Phoca groenlandica, using a sample of 155 known-age teeth from seals age 3 mo to 10 yr. Under transmitted light, transverse sections of harp seal ... -
Validation of pop-up satellite archival tags (PSATs) on Atlantic cod (Gadus morhua) in a Greenland fjord
(Peer reviewed; Journal article, 2023)Traditional tagging techniques are simple and cost-effective, but inferences require recaptures and data on movement/migration are limited to a start and end position at unpredictable intervals. Pop-up satellite archival ... -

Validation of three-dimensional hydrodynamic models in the Gulf of Finland based on a statistical analysis of a six-model ensemble
(ICES CM documents;2008/L:06, Working paper, 2008)Six three-dimensional hydrodynamic models were compared in their simulations of the hydrographic features of the Gulf of Finland in the Baltic Sea in the summer-autumn period of 1996. Validation was undertaken using more ... -
Validation of three-dimensional hydrodynamic models of the Gulf of Finland
(Journal article; Peer reviewed, 2010-10)A model-intercomparison study was conducted, the first of its kind for the Baltic Sea, whose aim was to systematically simulate the basic three-dimensional hydrographic properties of a realistic, complex basin. Simulations ... -
Validering av optimale mikronæringsstoff-nivå i laksefôr - ASSESSFEED
(Rapport fra havforskningen;21-2018, Research report, 2018)ASSESSFEED er et prosjekt utgått fra EU-prosjektet ARRAINA, med målsetning å validere nye anbefalinger for tilsetning av mikronæringsstoffer, særlig vannløselige vitaminer, i laksefôr. Det ble kjørt et fôingsforsøk der ... -
The value of applying commercial fishers' experience to designed surveys for identifying characteristics of essential fish habitat for adult summer flounder
(Journal article; Peer reviewed, 2008-06)Identifying the habitat requirements of marine fish is necessary to conserve and manage their populations, but these requirements are poorly understood for many species. One method of screening for important habitat ... -
Valuing blue carbon changes in the Arctic ocean
(Peer reviewed; Journal article, 2019)The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO2 supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and ... -

Vandring hos postsmolt av laks i Boknafjorden 2020 - Status for første året
(Rapport fra havforskningen;2020 - 49, Research report, 2020)For å kartlegge utvandringsperiode og vandring til smolt gjennom Boknafjorden ble laksesmolt fra Dirdalselven (N=48) i Høgsfjorden og Vikadalselven (N=23) i Vindafjord fanget og merket med akustiske merker. Fisken i ... -

Variabilities in stomach contents of cod, collected by demersal and pelagic trawl in the southern part of the Barents Sea
(ICES CM Documents;1990/G:3, Working paper, 1990)Samples of Northeast Arctic cod stomachs were collected separately on demersal and pelagic stations at the same date in February 1986 and were analysed for length group 30-40cm. The results indicate that the mean value ...
