Implications of density-dependent juvenile growth for compensatory recruitment regulation of haddock
(Journal article; Peer reviewed, 1999)Data from bottom trawl surveys conducted by Canada and the United States were used to describe temporal trends in the length of haddock ages 1–4 on the southwestern Scotian Shelf (SWSS) and Bay of Fundy. From 1970 to 1995, ... -
Implications of fisheries-induced evolution for population recovery: Refocusing the science and refining its communication
(Peer reviewed; Journal article, 2020)The argument that sufficiently high fishing mortality (selective or not) can effect genetic change in fished populations has gained considerable traction since the late 1970s. The intervening decades have provided compelling ... -
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 ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
(ICES CM documents;2010/M:29, Working paper, 2010)Fishing-induced evolution has the potential to change life-history and other characters of exploited stocks. Here we study the rebuilding and recovery of an exploited stock with en individual-based eco-genetic model ... -
Implications of tag positioning and performance on the analysis of cetacean movement
(Journal article; Peer reviewed, 2019)Background Satellite-linked animal-borne tags enable the study of free-ranging marine mammals. These tags can only transmit data while their antenna is above the surface for a sufficient amount of time. Thus, the position ... -
Import av fiskeyngel til norske farvann?
(Havforskningsnytt, Working paper, 1994) -
Import of Atlantic Water and sea ice controls the ocean environment in the northern Barents Sea
(Peer reviewed; Journal article, 2022)The northern Barents Sea is a cold, seasonally ice-covered Arctic shelf sea region that has experienced major warming and sea ice loss in recent decades. Here, a 2-year observational record from two ocean moorings provides ... -
Import of furunculosis to Norway with Atlantic salmon smolts from Scotland
(ICES CM Documents;1987/F:8, Working paper, 1987)In early summer 1985 the Norwegian Veterinary Authorities authorized the import of about 250.000 Atlantic salmon smolts from a fish farm at the west coast of Scotland to the Namdal region north of Trondheim. Immediately ... -
"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 ... -
Importance of fast ice and glacier fronts for female polar bears and their cubs during spring in Svalbard, Norway
(Journal article; Peer reviewed, 2012-02-13)Arctic sea ice is declining rapidly, making it vital to understand the importance of different types of sea ice for ice-dependent species such as polar bears Ursus maritimus. In this study we used GPS telemetry (25 polar ... -
Importance of genetic variation in the propagation of cod. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)During the last decade the existence of genetic diversity within species and populations has been generally accepted. The complex structure of populations as well as the variations within populations is believed to be ... -
Importance of heat transport and local air-sea heat fluxes for Barents Sea climate variability
(Journal article; Peer reviewed, 2010-07-22)An isopycnic coordinate ocean model has been used to investigate the importance of different mechanisms on the Barents Sea climate variability for the period 1948–2006 Observed and simulated time series from the Kola Section ... -

The Importance of Marine Research Infrastructures in Capturing Processes and Impacts of Extreme Events
(Peer reviewed; Journal article, 2021)Extreme events have long been underestimated in the extent to which they shape the surface of our planet, our environment, its ecological integrity, and the sustainability of human society. Extreme events are by definition ... -
The importance of microbiota and terrestrial inflows in controlling seston C:N:P:O:Si:Ca:Mn:Mg:Fe:K:Na:Cl:S:Cu:Zn stoichiometry of a deep coastal fjord
(Peer reviewed; Journal article, 2022)Comprehensive fjord-systems represent major extensions of the coastline and are therefore important transfer zones of materials from land to ocean. Despite increased terrestrial inflows to fjords due to climate changes, ... -
Importance of the swimbladder in acoustic scattering by fish: A comparison of gadoid and mackerel target strengths
(Journal article; Peer reviewed, 1980)Previous determinations of the swimbladder contribution to the fish backscattering cross section have been hindered by ignorance of the acoustic boundary conditions at the swimbladder wall. The present study circumvents ... -
Imprint of Climate Change on Pan-Arctic Marine Vegetation
(Peer reviewed; Journal article, 2020)The Arctic climate is changing rapidly. The warming and resultant longer open water periods suggest a potential for expansion of marine vegetation along the vast Arctic coastline. We compiled and reviewed the scattered ... -
Improved calibration of hydroacoustic equipment with copper spheres

Improved catch rates and selection of Norway lobster (Nephrops norvegicus L.) by controlled release of fluid bait extract in pot fishing
(ICES CM Documents;1992/B:14, Working paper, 1992)The effect of controlled release of fluid mackerel extract as bait in Norway lobster pots was tested in comparative fishing trials. Compared with natural mackerel bait, pots with extract release rates above 6 ml/h had ... -
Improved high throughput protocol for targeting eukaryotic symbionts in metazoan and eDNA samples
(Peer reviewed; Journal article, 2021)Eukaryote symbionts of animals are major drivers of ecosystems not only because of their diversity and host interactions from variable pathogenicity but also through different key roles such as commensalism and to different ...
