The Effect of Extraction Methodology on the Recovery and Distribution of Naphthenic Acids of oilfield Produced Water
(Journal article; Peer reviewed, 2019)Comprehensive chemical characterization of naphthenic acids (NAs) in oilfield produced water is a challenging task due to sample complexity. The recovery of NAs from produced water, and the corresponding distribution of ... -
The Effect of Optical Properties on Secchi Depth and Implications for Eutrophication Management
(Journal article; Peer reviewed, 2019)Successful management of coastal environments requires reliable monitoring methods and indicators. Besides Chlorophyll-a concentration (Chl-a), water transparency measured as Secchi Depth (ZSD) is widely used in Baltic Sea ... -
The effects of wildfire on the water chemistry of dilute, acidic lakes in southern Norway
(Journal article; Peer reviewed, 2014)Changes in lake water chemistry were studied for >4 years following a large wildfire in a boreal forest area in Mykland, southern Norway, an area characterized by thin and patchy, base-poor and slow-weathering soils and ... -
The Flow of IWRM in SADC: The Role of Regional Dynamics, Advocacy Networks and External Actors
(Journal article; Peer reviewed, 2016)This article explores the entry and spread of IWRM in the Southern African Development Community (SADC) region. It traces how the idea of IWRM was pro moted and sustained throughout the region by mapping key events, actors ... -
The future Dutch Environment and Planning Act in light of the ecosystem approach
(Journal article; Peer reviewed, 2018)This paper discusses whether the future Dutch Environment and Planning Act has embraced the ecosystem approach as a leading paradigm. -
The impact of an abandoned mercury mine on the environment in the Xiushan region, Chongqing, southwestern China
(Journal article; Peer reviewed, 2018)Mercury contamination is a serious problem in the Hg mining area of Xiushan County, Chongqing, southwestern China. The concentrations of total mercury (THg) and methylmercury (MeHg) in paddy soil, surface water, and rice ... -
The importance of year-to-year variation in meteorological and runoff forcing for water quality of a temperate, dimictic lake
(Journal article; Peer reviewed, 2015)Natural stochasticity can pose challenges in managing the quality of the environment, or hinder understanding of the system structure. It is problematic because unfavourable stochastic events cancel management efforts and ... -
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 influence of physical factors on kelp and sea urchin distribution in previously and still grazed areas in the NE Atlantic
(Journal article; Peer reviewed, 2014)The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. On a large scale, ... -
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 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 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 Suitability of the Ecosystem Services Framework for Guiding Benefit Assessments in Human-Modified Landscapes Exemplified by Regulated Watersheds—Implications for a Sustainable Approach
