Saltwater spawning grounds of sea-run brown trout (Salmo trutta) in tidal waters of a major Norwegian river
(Peer reviewed; Journal article, 2021)Sea-run brown trout (Salmo trutta) have a highly phenotypically plastic life history that allows them to be effective colonizers and competitors in freshwater. This paper documents a previously unknown spawning behaviour ... -

Carbon cycle feedbacks in an idealized simulation and a scenario simulation of negative emissions in CMIP6 Earth system models
(Peer reviewed; Journal article, 2024)Limiting global warming to well below 2 ∘C by the end of the century is an ambitious target that requires immediate and unprecedented emission reductions. In the absence of sufficient near-term mitigation, this target will ... -
Kartlegging av sjøørretvassdrag i Ørsta i 2022
(LFI - Laboratorium for ferskvannsøkologi og innlandsfiske;, Research report, 2024)«Mer laks og sjøørret på Sunnmøre» er et prosjekt ledet av organisasjonen Lakseelvene på Sunnmøre og finansiert av Hofseth Aqua AS med en rekke offentlige bidragsytere. Norwegian Research Centre ved faggruppen Laboratorium ... -
Seasonal Variability of the Surface Ocean Carbon Cycle: A Synthesis
(Peer reviewed; Journal article, 2023)The seasonal cycle is the dominant mode of variability in the air-sea CO2 flux in most regions of the global ocean, yet discrepancies between different seasonality estimates are rather large. As part of the Regional Carbon ... -
On the effect and monitoring of organic enrichment in marine sediments associated with Atlantic salmon farms: towards greater environmental sustainability
(Research report, 2019)This is a preliminary report of a case study around a Norwegian aquaculture farm designed to test novel suitable methods that could be applied across different locations within an EU project. The main goal was to validate ... -
Metabarcoding of sediment eDNA communities at the Hywind Scotland OWF – A pilot study
(Research report, 2023)Environmental impact assessment and regular environmental monitoring of marine life are prerequisites for the construction, operation, and decommissioning of offshore wind farms (OWFs). Molecular methods such as metagenomics, ... -
Future projections of wind energy potentials in the arctic for the 21st century under the RCP8.5 scenario from regional climate models (Arctic-CORDEX)
(Peer reviewed; Journal article, 2023)The Arctic has warmed more than twice the rate of the entire globe. To quantify possible climate change effects, we calculate wind energy potentials from a multi-model ensemble of Arctic-CORDEX. For this, we analyze future ... -
Valve gaping behaviour in the European oyster (Ostrea edulis) in response to changes in light intensity when combined with variations in salinity and seawater temperature
(Journal article; Peer reviewed, 2023)Valve gaping behaviour in bivalve molluscs controls the flow of water across gills that provides both food, and oxygen for respiration. Closure of the valves also provides protection from predators and poor-quality water ... -
Kartlegging av råstoff som grunnlag for proteinkilder til fôr i Rogaland
(Research report, 2023)Rapporten gir en oversikt over den regionale råstoffsituasjonen for fôrproduksjon i Rogaland. Fokus i rapporten er på tilgjengelig råstoff for protein. Kilder til EPA/DHA er dermed ikke vurdert. Rogaland er et spennende ... -

Machine learning reveals regime shifts in future ocean carbon dioxide fluxes inter-annual variability
(Peer reviewed; Journal article, 2024)The inter-annual variability of global ocean air-sea CO2 fluxes are non-negligible, modulates the global warming signal, and yet it is poorly represented in Earth System Models (ESMs). ESMs are highly sophisticated and ... -
Three major mesoplanktonic communities resolved by in situ imaging in the upper 500 m of the global ocean

Stronger Oceanic CO2 Sink in Eddy-Resolving Simulations of Global Warming
(Peer reviewed; Journal article, 2024)Accurately representing the ocean carbon cycle in Earth System Models (ESMs) is essential to understanding the oceanic CO2 sink evolution under CO2 emissions and global warming. A key uncertainty arises from the ESM's ... -
What goes in must come out: the oceanic outgassing of anthropogenic carbon
(Peer reviewed; Journal article, 2024)About 25% of the emitted anthropogenic CO2 is absorbed by the ocean and transported to the interior through key gateways, such as the Southern Ocean or the North Atlantic. Over the next few centuries, anthropogenic CO2 is ... -
Deep-Reaching Global Ocean Overturning Circulation Generated by Surface Buoyancy Forcing
(Peer reviewed; Journal article, 2023)In contrast with the atmosphere, which is heated from below by solar radiation, the ocean is both heated and cooled from above. To drive a deep-reaching overturning circulation in this context, it is generally assumed that ...
