    • Trends and patterns in surface water chemistry in Europe and North America between 1990 and 2016, with particular focus on changes in land use as a confounding factor for recovery 

      Garmo, Øyvind Aaberg; Kaste, Øyvind; Arle, Jens; Austnes, Kari; de Wit, Heleen; Fölster, Jens; Houle, Daniel; Hruska, Jakub; Indriksone, Iveta; Monteith, Don; Rogora, Michaela; Sample, James Edward; Steingruber, Sandra; Stoddard, John L.; Talkop, Reet; Trodd, Wayne; Ulańczyk, Rafał Piotr; Vuorenmaa, Jussi (NIVA-rapport;7479, Research report, 2020)
      The report presents trends in sulphate, nitrate, chloride, base cations, ANC (acid neutralising capacity), pH and DOC at circa 500 ICP Waters sites in Europe and North America for the period 1990-2016. Time series were ...
    • Trends and patterns in surface water chemistry in Europe and North America between 1990 and 2020, with a focus on calcium 

      Vogt, Rolf David; Agnieszka, Kolada; Arle, Jens; Austnes, Kari; Van Dam, Herman; Futter, Martyn; Fölster, Jens; Gundersen, Cathrine Brecke; Higgins, Scott N.; Houle, Daniel; Hruska, Jakub; Monteith, Don; Paterson, Andrew; Rogora, Michela; Sample, James Edward; Stoddard, John; Steingruber, Sandra; Ulanczyk, Rafak; Vuorenmaa, Jussi; de Wit, Heleen (NIVA-rapport;7931-2024, Research report, 2024)
      The report presents trends in major anions and cations, pH, TOC and bicarbonate in surface waters in Europe and North America from 1990 to 2020. Special attention is given to trends in calcium, which showed some unexpected ...
    • Trends in surface water chemistry in acidified areas in Europe and North America from 1990 to 2008 

      Garmo, Øyvind Aaberg; Skjelkvåle, Brit Lisa; de Wit, Heleen; Colombo, Luca; Curtis, Chris; Fölster, Jens; Hoffmann, Andreas; Hruška, Jakub; Høgåsen, Tore; Jeffries, Dean S.; Keller, W.
