The influence of a submerged meadow on uptake and trophic transfer of legacy mercury from contaminated sediment in the food web in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2019)There are contradicting results on the importance of legacy mercury (Hg) contaminated sediments to Hg fish tissue concentrations. Still, sediment remediation actions often aim at minimizing ecosystem exposure and human ... -
The influence of permanently submerged macrophytes on sediment mercury distribution, mobility and methylation potential in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2018)Macrophytes are shown to affect the microbial activity in different aqueous environments, with an altering of the sediment cycling of mercury (Hg) as a potential effect. Here, we investigated how a meadow with permanently ... -
The INtegrated CAtchment model of phosphorus dynamics (INCA-P): Description and demonstration of new model structure and equations
(Journal article; Peer reviewed, 2016)INCA-P is a dynamic, catchment-scale phosphorus model which has been widely applied during the last decade. Since its original release in 2002, the model structure and equations have been significantly altered during several ... -
The kelp cultivation potential in coastal and offshore regions of Norway
(Journal article; Peer reviewed, 2019)We have evaluated the cultivation potential of sugar kelp (Saccharina latissima) as a function of latitude and position (near- and offshore) along the Norwegian coast using a coupled 3D hydrodynamic-biogeochemical-kelp ... -
The major threats to Atlantic salmon in Norway
(Journal article; Peer reviewed, 2017)Atlantic salmon (Salmo salar) is an economically and culturally important species. Norway has more than 400 watercourses with Atlantic salmon and supports a large proportion of the world’s wild Atlantic salmon. Atlantic ... -
The Norwegian river monitoring programme – water quality status and trends 2017
(NIVA-rapport;7313, Research report, 2018)From 2017, the Norwegian River Monitoring Programme (Elveovervåkingsprogrammet) replaced the former RID programme “Riverine inputs and direct discharges to Norwegian coastal waters” which had run continuously since 1990. ... -
The occurrence and spread of Gonyostomum semen (Ehr.) Diesing (Raphidophyceae) in Norwegian lakes
(Journal article; Peer reviewed, 2014)The invasive and nuisance microalga Gonyostomum semen has recently expanded its geographical distribution and increased its biomass in Sweden and Finland. Temperatures, total organic carbon (TOC), water colour and phosphorous ... -
The organic pollutant status of rivers in Bosnia and Herzegovina as determined by a combination of active and passive sampling methods
(Journal article; Peer reviewed, 2018)There is an overall lack of data concerning the pollution status of Bosnia Herzegovina, which is confounded by fragmented national environmental management. The present study aimed to provide some initial data for ... -
The potential effects on water quality of intensified forest management for climate mitigation in Norway
(NIVA-rapport;7363, Research report, 2019)The objective of this study was to make an overview assessment of the potential effects of intensified forest management, promoted by the Norwegian government as a climate mitigation measure, on water quality in Norwegian ... -
The role of charophytes (Charales) in past and present environments: An overview
(Journal article; Peer reviewed, 2015)Charophytes, i.e. extant and fossil members of the order Charales plus the members of the extinct orders Sycidiales and Moellerinales, are closely related to modern land plants. These algae have a complex morphology, and ... -
The social-ecological value of recreational fishing for sea trout; a potential for further development of the experience industry in Aust-Agder? (TROUT XP)
(NIVA-rapport;7356, Research report, 2019)Prosjektet undersøkte hvilken betydning det å få sjøørret har for fritidsfiskere i form av fiskeglede og videre hva som er viktig for en god fiskeopplevelse. Bakgrunnen for dette er å få i stand et europeisk samarbeid og ... -
The Suitability of the Ecosystem Services Framework for Guiding Benefit Assessments in Human-Modified Landscapes Exemplified by Regulated Watersheds—Implications for a Sustainable Approach
(Journal article; Peer reviewed, 2019)To support decision-making, benefit assessments have become an obligatory part of natural resource management. In this context, the ecosystem services (ES) framework has been widely adopted for identifying and assessing ... -
The Water Column Monitoring Programme 2013: Determining the biological effects of two offshore platforms on local fish populations
(NIVA-rapport;6595, Research report, 2013)The biological effects of two offshore oil platforms on local fish populations were assessed as part of the Water Column Monitoring (WCM) programme for 2013. Wild fish were caught with baited rod and line from within the ... -
The “Forgotten” Ecology Behind Ecological Status Evaluation: Re-Assessing the Roles of Aquatic Plants and Benthic Algae in Ecosystem Functioning
(Journal article; Peer reviewed, 2016)Aquatic plants and benthic algae have long been used as indicators for nutrient enrichment in lakes and streams. Evaluations of the performance of indices calculated from species assemblages of aquatic plants and algae are ... -
