Utslipp til sjø – kan enkle modeller gi tilstrekkelig grunnlag for vurdering av spredning, fortynning og surhetsgrad?
(Journal article; Peer reviewed, 2018)Det forelå i 2016 ca. 2500 utslippstillatelser for utslipp til kystvann i Norge. Til tross for mange bestrebelser på å redusere utslippene må en forvente at en også i fremtiden må leve med betydelige utslipp til sjø. For ... -

(NIVA-rapport;7331, Research report, 2018)I forbindelse med planarbeid for utvidelse av Fv. 564 Ulset-Slettestølvegen i Åsane i Bergen er det utført en forundersøkelse av økologisk tilstand i vassdrag innenfor planområdet, og vurdering av naturfaglige verdier. ... -
UV radiation affects antipredatory defense traits in Daphnia pulex
(Peer reviewed; Journal article, 2020)In aquatic environments, prey perceive predator threats by chemical cues called kairomones, which can induce changes in their morphology, life histories, and behavior. Predator‐induced defenses have allowed for prey, such ... -
Validation of a Method for Extracting Microplastics from Complex, Organic-Rich, Environmental Matrices
(Journal article; Peer reviewed, 2018)Complex and organic-rich solid substrates such as sludge and soil have been shown to be contaminated by microplastics; however, methods for extracting plastic particles have not yet been systemically tested or standardized. ... -
Valuing the ecosystem service benefits from kelp forest restoration: A choice experiment from Norway
(Peer reviewed; Journal article, 2021)Habitat loss and degradation are recognised as the most important causes of species decline and extinction in marine ecosystems. It is also widely recognised that a range of restoration actions are now essential to halt ... -
Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic
(Peer reviewed; Journal article, 2020)Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of ... -
Variability in the anatoxin gene clusters of Cuspidothrix issatschenkoi from Germany, New Zealand, China and Japan
(Journal article; Peer reviewed, 2018)Anatoxin-a and homoanatoxin-a are neurotoxic cyanotoxins produced by benthic and planktonic cyanobacteria worldwide. These toxins are produced by the cyanobacterial genera Dolichospermum, Cuspidothrix, Phormidium, Oscillatoria, ... -
Variability in the sxt Gene Clusters of PSP Toxin Producing Aphanizomenon gracile Strains from Norway, Spain, Germany and North America
(Journal article; Peer reviewed, 2016)Paralytic shellfish poisoning (PSP) toxin production has been detected worldwide in the cyanobacterial genera Anabaena, Lyngbya, Scytonema, Cuspidothrix and Aphanizomenon. In Europe Aphanizomenon gracile and Cuspidothrix ... -
Variation in Phenolic Chemistry in Zostera marina Seagrass Along Environmental Gradients
(Peer reviewed; Journal article, 2021)Chemical ecology has been suggested as a less time-consuming and more cost-efficient monitoring tool of seagrass ecosystems than traditional methods. Phenolic chemistry in Zostera marina samples was analyzed against latitude, ... -
Variation in population structure and standing stocks of kelp along multiple environmental gradients and implications for ecosystem services
(Peer reviewed; Journal article, 2021)There is an increasing focus on ecosystem services provided by macroalgae worldwide, many which depend on its structural and morphological characteristics. Here we investigated how characteristics of canopy kelp plants of ... -
Variations of Drinking Water Quality Influenced by Seasons and Household Interventions: A Case Study from Rural Maharashtra, India
(Journal article; Peer reviewed, 2017)The majority of people in rural villages in Maharashtra, India, have access to improved drinking water sources. Nevertheless, the water quality at the point of consumption often does not satisfy the drinking water standard. ... -
Vertical mixing and internal wave energy fluxes in a sill fjord
(Journal article; Peer reviewed, 2016)We consider the distribution and level of local vertical mixing inside of the Drøbak Sill in the Oslofjord, Norway. The work is motivated by observations of long periods (∼years) of hypoxic or even anoxic conditions in the ... -
Vertical Mixing in Stratified Fjords Near Tidewater Outlet Glaciers Along Northwest Greenland
(Peer reviewed; Journal article, 2021)Vertical mixing of upper water masses in Arctic fjords is important for circulation and transport of nutrients and heat. However, the distribution of turbulent mixing is poorly known. Here we present hydrographic and ... -
Volcanically hosted venting with indications of ultramafic influence at Aurora hydrothermal field on Gakkel Ridge
(Peer reviewed; Journal article, 2022)The Aurora hydrothermal system, Arctic Ocean, hosts active submarine venting within an extensive field of relict mineral deposits. Here we show the site is associated with a neovolcanic mound located within the Gakkel Ridge ... -
Vulnerability of Aquatic Insect Species to Insecticides, Depending on Their Flight Period and Adult Life Span
(Peer reviewed; Journal article, 2021)Effects of insecticides on terrestrial adult life stages of otherwise aquatic insects, such as mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera), are largely unknown. In the present study, a ... -
Vurdering av biotilgjengelighetsmodeller som verktøy for karakterisering av resipienters sårbarhet for metallforurensing fra veg
