Long-term changes (1990–2015) in the atmospheric deposition and runoff water chemistry of sulphate, inorganic nitrogen and acidity for forested catchments in Europe in relation to changes in emissions and hydrometeorological conditions
(Journal article; Peer reviewed, 2018)The international Long-Term Ecological Research Network (ILTER) encompasses hundreds of long-term research/monitoring sites located in a wide array of ecosystems that can help us understand environmental change across the ... -
Long-term coastal monitoring data show nutrient-driven reduction in chlorophyll
(Peer reviewed; Journal article, 2020)In this study we have compiled a long-term monitoring dataset from the inner Oslofjorden and supplemented it with short-term research data from the same station. Using generalized additive models analysing the data from ... -
Long-term effects of thin layer capping in the Grenland fjords, Norway: Reduced uptake of dioxins in passive samplers and sediment-dwelling organisms
(Peer reviewed; Journal article, 2020)The Grenlandfjords in South East Norway are severely contaminated with dioxins from a magnesium smelter operated between 1950 and 2001. In 2009, the proposal of thin-layer capping as a potential mitigation method to reduce ... -
Long-term mark-recapture and growth data for large-sized migratory brown trout (Salmo trutta) from Lake Mjøsa, Norway
(Peer reviewed; Journal article, 2020)Long-term data from marked animals provide a wealth of opportunities for studies with high relevance to both basic ecological understanding and successful management in a changing world. The key strength of such data is ... -

Long-term response of marine benthic fauna to thin-layer capping with powdered activated carbon in the Grenland fjords, Norway
(Peer reviewed; Journal article, 2021)The Grenland fjords in Norway have a long history of contamination by large emissions of dioxins and mercury. As a possible sediment remediation method in situ, thin-layer capping with powdered activated carbon (AC) mixed ... -
Long-term rise in riverine dissolved organic carbon concentration is predicted by electrolyte solubility theory
(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 ... -

Long-term temporal and spatial trends in eutrophication status of the Baltic Sea
(Journal article; Peer reviewed, 2015)Much of the Baltic Sea is currently classified as ‘affected by eutrophication’. The causes for this are twofold. First, current levels of nutrient inputs (nitrogen and phosphorus) from human activities exceed the natural ... -
Lovravatnets kvalitet. Vurdering av Lovravatnets kvalitet, tiltak for å gjøre vannkvaliteten bedre egnet som råvannskilde for settefiskproduksjon og forslag til overvåking
