    • Critical loads and the MAGIC model. Evaluating the country-scale applications in Norway using data from the 2019 national lake survey 

      Austnes, Kari; Wright, Richard Frederic; Sample, James Edward; Clayer, Francois (NIVA-rapport;7557, Research report, 2020)
      The critical loads methodology used at the national scale in Norway and the MAGIC model as applied to the lakes in the national 1000-lake survey have been evaluated, making use of the data from the 2019 national lake survey. ...

    • Intensified forestry as a climate mitigation measure – how can it affect critical loads for S and N deposition? 

      Kaste, Øyvind; Wright, Richard Frederic; Valinia, Salar (NIVA-rapport;7436, Research report, 2019)
      More intensive forestry has been proposed in Norway as a climate mitigation measure. Growing forests capture CO2 from the atmosphere and the harvested biomass can comprise a carbon sink. Changes in forestry practices, ...

    • Measuring amines in Norwegian surface waters 

      Poste, Amanda; Grung, Merete; Wright, Richard Frederic (NIVA-rapport;6781, Research report, 2015)
      In summer 2012 we carried out a survey of amine concentrations in 21 Norwegian lakes with the aim of assessing the prevalence of amines in Norwegian lakes and identifying the main factors affecting concentrations of these ...

    • Nitrogen in surface waters: time trends and geographical patterns explained by deposition levels and catchment characteristics 

      Austnes, Kari; Hjermann, Dag Øystein; Sample, James Edward; Wright, Richard Frederic; Kaste, Øyvind; de Wit, Heleen (NIVA-rapport;7728-2022, Research report, 2022)
      The report presents a statistical analysis of controls (deposition, land cover, climate) on spatial variability and long-term trends (1992-2016) in surface water concentrations of nitrate (NO3) and carbon to nitrogen (C/N) ...

    • Re-calibration of the MAGIC model with data from the National Lake Survey 2019. 

      Kaste, Øyvind; Norling, Magnus Dahler; Austnes, Kari; Cosby, Bernard J.; Wright, Richard Frederic (NIVA-rapport;7799-2022, Research report, 2022)
      The MAGIC model (Model for Acidification of Groundwater In Catchments) was calibrated to the Norwegian 1000-lake survey data from both 1995 and 2019. The re-survey in 2019 provided a new point in time for generation of new ...

    • Regional assessment of the current extent of acidification of surface waters in Europe and North America 

      Austnes, Kari; Aherne, Julian; Arle, Jens; Čičendajeva, Marina; Couture, Suzanne; Fölster, Jens; Garmo, Øyvind Aaberg; Hruska, Jakub; Monteith, Don; Posch, Max; Rogora, Michaela; Sample, James Edward; Skjelkvåle, Brit Lisa; Steingruber, Sandra; Stoddard, John L.; Ulańczyk, Rafał; Van Dam, Herman; Velasco, Manuel Toro; Vuorenmaa, Jussi; Wright, Richard Frederic; de Wit, Heleen (NIVA-rapport;7268, Research report, 2018)
      The current status of surface water acidification related to air pollution in Europe and North America has been assessed using country reports, monitoring data, critical loads and exceedance data, acid sensitivity and ...

    • Uncertainties in assessing the environmental impact of amine emissions from a CO 2 capture plant 

      Karl, Matthias; Castell, Núria; Simpson, David; Solberg, Sverre; Starrfelt, Jostein; Svendby, Tove Marit; Walker, Sam-Erik; Wright, Richard Frederic (Journal article; Peer reviewed, 2014)
      In this study, a new model framework that couples the atmospheric chemistry transport model system WRF-EMEP and the multimedia fugacity level III model was used to assess the environmental impact of amine emissions to air ...
