Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
(Journal article; Peer reviewed, 2000-06-26)The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of the estuary and Gulf of St. ... -
Impact of variable physical conditions and future increased aquaculture production on lice infestation pressure and its sustainability in Norway
(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -

(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -
Impacts of a Changing Ecosystem on the Feeding and Feeding Conditions for Atlantic Salmon During the First Months at Sea
(Peer reviewed; Journal article, 2022)During the last decades, many wild Atlantic salmon populations have declined dramatically. One hypothesis for an observed reduction in salmon marine growth and survival is reduced abundance of prey. However, the effect of ... -
Impacts of bottom trawling and litter on the seabed in Norwegian waters
(Journal article; Peer reviewed, 2018)Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern ... -
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 ... -
Impacts of extreme weather events on transport infrastructure in Norway

Impacts of glacial and sea-ice meltwater, primary production and ocean CO2 uptake on ocean acidification state of waters by the 79 North Glacier and northeast Greenland shelf
(Peer reviewed; Journal article, 2023)The waters adjacent to the Nioghalvfjerdsbræ (79 North Glacier, 79NG) are influenced by Greenland Ice Sheet (GrIS) melt, sea-ice meltwater, and waters on the adjacent northeast Greenland shelf (NEGS). We investigated ocean ... -

Impacts of parasites on marine survival of Atlantic salmon: a meta-analysis
(Peer reviewed; Journal article, 2016)Parasites can, in theory, have large impacts on the survival of fish populations. One method to evaluate such impacts on anadromous species is to apply manipulative field experiments in which parallel groups of antiparasitically ... -
Impacts of salmon lice on mortality, marine migration distance and premature return in sea trout
(Peer reviewed; Journal article, 2020)Brown trout Salmo trutta (L.) is a facultative anadromous species, where a portion of individuals in populations with access to the sea perform migrations to use the richer feeding resources. We investigated the effect of ... -
Impacts of wild fishes attracted to open-cage salmonid farms in Norway
(Journal article; Peer reviewed, 2014-12-02)Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around ... -
Implementation and evaluation of open boundary conditions for sea ice in a regional coupled ocean (ROMS) and sea ice (CICE) modeling system
(Peer reviewed; Journal article, 2022)The Los Alamos Sea Ice Model (CICE) is used by several Earth system models where sea ice boundary conditions are not necessary, given their global scope. However, regional and local implementations of sea ice models require ... -
Implications for introgression: Has selection for fast growth altered the size threshold for precocious male maturation in domesticated Atlantic salmon?
(Peer reviewed; Journal article, 2018) -
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 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 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 ...
