Comparing in situ turbidity sensor measurements as a proxy for suspended sediments in North-Western European streams
Skarbøvik, Eva; Gyritia Madsen van't Veen, Sofie; Lannergård, Emma E.; Wenng, Hannah Tabea; Stutter, Marc; Bieroza, Magdalena; Atcheson, Kevin; Jordan, Philip; Fölster, Jens; Mellander, Per-Erik; Kronvang, Brian; Marttila, Hannu; Kaste, Øyvind; Lepistö, Ahti; Kämäri, Maria (Peer reviewed; Journal article, 2023)Climate change in combination with land use alterations may lead to significant changes in soil erosion and sediment fluxes in streams. Optical turbidity sensors can monitor with high frequency and can be used as a proxy ... -
Land Use Change to Reduce Freshwater Nitrogen and Phosphorus will Be Effective Even with Projected Climate Change
Wade, Andrew J.; Skeffington, Richard A.; Couture, Raoul-Marie; Lampa, Martin Erlandsson; Groot, Simon; Halliday, Sarah J.; Harezlak, Valesca; Hejzlar, Josef; Jackson-Blake, Leah Amber; Lepistö, Ahti; Papastergiadou, Eva; Riera, Joan Lluis; Rankinen, Katri; Shahgedanova, Maria; Trolle, Dennis; Whitehead, Paul G.; Psaltopoulos, Demetris; Skuras, Dimitris (Peer reviewed; Journal article, 2022)Recent studies have demonstrated that projected climate change will likely enhance nitrogen (N) and phosphorus (P) loss from farms and farmland, with the potential to worsen freshwater eutrophication. Here, we investigate ... -
Land-use dominates climate controls on nitrogen and phosphorus export from managed and natural Nordic headwater catchments
de Wit, Heleen A; Lepistö, Ahti; Marttila, Hannu; Wenng, Hannah; Bechmann, Marianne; Blicher-Mathiesen, Gitte; Eklöf, Karin; Futter, Martyn N.; Kortelainen, Pirkko; Kronvang, Brian; Kyllmar, Katarina; Rakovic, Jelena (Peer reviewed; Journal article, 2020)Agricultural, forestry‐impacted and natural catchments are all vectors of nutrient loading in the Nordic countries. Here, we present concentrations and fluxes of total nitrogen (totN) and phosphorus (totP) from 69 Nordic ... -
Potential impacts of a future Nordic bioeconomy on surface water quality
Marttila, Hannu; Lepistö, Ahti; Tolvanen, Anne; Bechmann, Marianne; Kyllmar, Katarina; Juutinen, Artti; Wenng, Hannah Tabea; Skarbøvik, Eva; Futter, Martyn; Kortelainen, Pirkko; Rankinen, Katri; Hellsten, Seppo; Kløve, Bjørn; Kronvang, Brian; Kaste, Øyvind; Solheim, Anne Lyche; Bhattacharjee, Joy; Rakovic, Jelena; de Wit, Heleen (Peer reviewed; Journal article, 2020)Nordic water bodies face multiple stressors due to human activities, generating diffuse loading and climate change. The ‘green shift’ towards a bio-based economy poses new demands and increased pressure on the environment. ...
