Cleaner air reveals growing influence of climate on dissolved organic carbon trends in northern headwaters
de Wit, Heleen; Stoddard, John L.; Monteith, Donald T.; Sample, James E.; Austnes, Kari; Couture, Suzanne; Fölster, Jens; Higgins, Scott N.; Houle, Daniel; Hruška, Jakub; Krám, Pavel; Kopáček, Jiří; Paterson, Andrew M.; Valinia, Salar; Van Dam, Herman; Vuorenmaa, Jussi; Evans, Chris D. (Peer reviewed; Journal article, 2021)Surface water browning, the result of increasing concentrations of dissolved organic matter (DOM), has been widespread in northern ecosystems in recent decades. Here, we assess a database of 426 undisturbed headwater lakes ... -
Long-term rise in riverine dissolved organic carbon concentration is predicted by electrolyte solubility theory
Monteith, Donald T.; Henrys, Peter A.; Hruška, Jakub; de Wit, Heleen; Krám, Pavel; Moldan, Filip; Posch, Maximilian; Räike, Antti; Stoddard, John L.; Shilland, Ewan M.; Gloria Pereira, Pereira; Evans, Chris D. (Peer reviewed; Journal article, 2023)The riverine dissolved organic carbon (DOC) flux is of similar magnitude to the terrestrial sink for atmospheric CO2, but the factors controlling it remain poorly determined and are largely absent from Earth system models ... -

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 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. Bill; Krám, Pavel; Majer, Vladimir; Monteith, Don T.; Paterson, Andrew M.; Rogora, Michela; Rzychon, Dorota; Steingruber, Sandra; Stoddard, John L.; Vuorenmaa, Jussi; Worsztynowicz, Adam (Journal article; Peer reviewed, 2014)Acidification of lakes and rivers is still an environmental concern despite reduced emissions of acidifying compounds. We analysed trends in surface water chemistry of 173 acid-sensitive sites from 12 regions in Europe and ...
