(NIVA-rapport;7014, Research report, 2016)Det er gjennomført undersøkelser av fysisk–kjemiske og biologiske forhold i vannforekomsten Segeråga, Rødøy kommune. Hensikten har vært å få frem en oppdatert staus for vannkvalitet og økologisk tilstand med fokus på ... -
Seks innsjøer i Ringsaker kommune. Overvåking av miljøtilstanden i 2017
(NIVA-rapport;7275, Research report, 2018)Rapporten omhandler vannkvalitet, biologiske forhold og økologisk tilstand i fem innsjøer i Ringsakfjellet samt innsjøen Næra med tilløpsbekker. Samlet klassifisering av økologisk tilstand basert på planteplankton og ... -
Selection of indicator contaminants of emerging concern when reusing reclaimed water for irrigation — A proposed methodology
(Peer reviewed; Journal article, 2023)Organic and microbial contaminants of emerging concern (CECs), even though not yet regulated, are of great concern in reclaimed water reuse projects. Due to the large number of CECs and their different characteristics, it ... -
Selection of the optimal extraction protocol to investigate the interaction between trace elements and environmental plastic
(Peer reviewed; Journal article, 2023)The interaction between environmental plastic and trace elements is an issue of concern. Understanding their interaction mechanisms is key to evaluate the potential threats for the environment. To this regard, consolidating ... -
Self Adjusting Algorithm for the Nontargeted Feature Detection of High Resolution Mass Spectrometry Coupled with Liquid Chromatography Profile Data
(Journal article; Peer reviewed, 2019)Nontargeted feature detection in data from high resolution mass spectrometry is a challenging task, due to the complex and noisy nature of data sets. Numerous feature detection and preprocessing strategies have been developed ... -
Self-reports of consumption of amphetamines, cocaine and heroin in a survey among marginalized drug users
(Journal article, 2014)Scientific literature offers few measurements of the quantities consumed by individual drug users. Such measurements are used for calculating the total drug consumption by the quantity-frequency method, and are extremely ... -
Sensitivity of modelled North Sea cod larvae transport to vertical behaviour, ocean model resolution and interannual variation in ocean dynamic
(Journal article; Peer reviewed, 2018)Transport with ocean currents affects the spatial distribution and survival of fish eggs and larvae and thereby population connectivity. Biophysical models are commonly used to understand these dynamics. Advancements such ... -
The sensitivity of primary productivity in Disko Bay, a coastal Arctic ecosystem, to changes in freshwater discharge and sea ice cover
(Peer reviewed; Journal article, 2023)The Greenland ice sheet is melting, and the rate of ice loss has increased 6-fold since the 1980s. At the same time, the Arctic sea ice extent is decreasing. Meltwater runoff and sea ice reduction both influence light and ... -
Sensitivity of the green algae Chlamydomonas reinhardtii to gamma radiation: Photosynthetic performance and ROS formation
(Journal article; Peer reviewed, 2017)The aquatic environment is continuously exposed to ionizing radiation from both natural and anthropogenic sources, making the characterization of ecological and health risks associated with radiation of large importance. ... -
Sensorbasert overvåking av nedbørstyrte utslipp til vann - fagrapport
(NIVA-rapport;7286, Research report, 2018)Nedbør på Saint-Gobain Ceramic Materials (SGCM) sitt produksjonsområde i Lillesand blir samlet i overvannsystemet og føres til Moelva. Partikler som har blitt avsatt på tak, asfaltflater og andre harde overflater transporteres ... -
Shifted dynamics of plankton communities in a restored lake: exploring the effects of climate change on phenology through four decades
(Peer reviewed; Journal article, 2022)Lake surface temperatures have increased globally in recent decades. Climate change can affect lake biota directly via enhanced water temperatures, shorter ice cover duration and prolonged stratification, and indirectly ... -
Shifts between sugar kelp and turf algae in Norway: regime shifts or flips between different opportunistic seaweed species?
(Journal article; Peer reviewed, 2019)Around year 2000, sugar kelp (Saccharina latissima) forests were observed to disappear in southern parts of Norway, being replaced by mats of turf algae (i.e. filamentous ephemeral algae) loaded with sediments. About 80% ... -
Shifts in flood generation processes exacerbate regional flood anomalies in Europe
(Peer reviewed; Journal article, 2023)Anomalies in the frequency of river floods, i.e., flood-rich or -poor periods, cause biases in flood risk estimates and thus make climate adaptation measures less efficient. While observations have recently confirmed the ... -
Short-term effects of macrophyte removal on aquatic biodiversity in rivers and lakes
(Peer reviewed; Journal article, 2022)Mass development of macrophytes is an increasing problem in many aquatic systems worldwide. Dense mats of macrophytes can negatively affect activities like boating, fishing or hydropower production and one of the management ... -
Short-term effects of macrophyte removal on emission of CO2 and CH4 in shallow lakes
(Peer reviewed; Journal article, 2022)Mass development of macrophytes in freshwater ecosystems is today considered a worldwide problem and substantial resources are spent on macrophyte removal each year. By removing the dominant primary producer, however, this ... -
