A 1-Dimensional Sympagic–Pelagic–Benthic Transport Model (SPBM): Coupled Simulation of Ice, Water Column, and Sediment Biogeochemistry, Suitable for Arctic Applications
(Journal article; Peer reviewed, 2019)Marine biogeochemical processes can strongly interact with processes occurring in adjacent ice and sediments. This is especially likely in areas with shallow water and frequent ice cover, both of which are common in the ... -
A carbon balance of Norway: terrestrial and aquatic carbon fluxes
(Journal article; Peer reviewed, 2015)Northern landscapes accumulate carbon in vegetation and soils while rivers transport significant amounts of land-derived carbon to coastal areas. Here, we quantify carbon sources and sinks in main ecosystems (forests, ... -
A Cost-effective Strategy for Pollution Abatement in the Hernad Catchment, Hungary
(NIVA-rapport;3355, Research report, 1996)The overall aims of this study are to elaborate tools for a more cost-effective and recipient oriented water management, and to conduct a specific abatement analysis in the Hernad catchment area. The Hernad river is ... -
A coulometric Gran titration method for the determination of strong and weak acids in freshwater
(NIVA-rapport;2019, Research report, 1987)A modefied Gran titration procedure for the determination of strong and weak acids in freshwater is described. The titrations are carried out by coulometric generation of hydroxide ions in the pH range 3.6-10.3. The method ... -
A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
(Journal article; Peer reviewed, 2018)Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ... -
A fatty acid based bayesian approach for inferring diet in aquatic consumers
(Journal article; Peer reviewed, 2015)We modified the stable isotope mixing model MixSIR to infer primary producer contributions to consumer diets based on their fatty acid composition. To parameterize the algorithm, we generated a ‘consumer-resource library’ ... -
