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
(Journal article; Peer reviewed, 2015)Building, traffic and maintenance of road can lead to increased supply of metals to water bodies. The metals’ physico-chemical speciation and bioavilability toward aquatic organisms depend on water chemical variables such ... -
Wastewater-based estimation of the prevalence of gout in Australia
(Peer reviewed; Journal article, 2020)Allopurinol, a first-line gout treatment drug in Australia, was assessed as a wastewater-based epidemiology biomarker of gout via quantification of the urinary metabolite, oxypurinol in wastewater. The in-sewer stability ... -
Water browning controls adaptation and associated trade-offs in phytoplankton stressed by chemical pollution
(Peer reviewed; Journal article, 2020)The acquisition of tolerance to an environmental stressor can result in organisms displaying slower growth after stress release. While well-grounded in the theory, empirical evidence of the trade-off between stress tolerance ... -
Water Flow Requirements of Post-smolt Atlantic Salmon (Salmo salar L.) Reared in Intensive Seawater Flow-through Systems: A Physiological Perspective
(Peer reviewed; Journal article, 2023)Environmental challenges related to open sea cage production of Atlantic salmon have sparked interest in developing commercial-scale semi-closed sea systems for post-smolt Atlantic salmon (100–1000 g). Determining the ... -
Water-borne pharmaceuticals reduce phenotypic diversity and response capacity of natural phytoplankton communities
(Journal article; Peer reviewed, 2017)Chemical micropollutants occur worldwide in the environment at low concentrations and in complex mixtures, and how they affect the ecology of natural systems is still uncertain. Dynamics of natural communities are driven ... -
