OECD validation study to assess intra- and inter-laboratory reproducibility of the zebrafish embryo toxicity test for acute aquatic toxicity testing
(Journal article; Peer reviewed, 2014)The OECD validation study of the zebrafish embryo acute toxicity test (ZFET) for acute aquatic toxicity testing evaluated the ZFET reproducibility by testing 20 chemicals at 5 different concentrations in 3 independent runs ... -
Olisthodiscus represents a new class of Ochrophyta
(Peer reviewed; Journal article, 2021)The phylogenetic diversity of Ochrophyta, a diverse and ecologically important radiation of algae, is still incompletely understood even at the level of the principal lineages. One taxon that has eluded simple classification ... -
On the Possibility of Aerobic Methane Production by Pelagic Microbial Communities of the Laptev Sea
(Peer reviewed; Journal article, 2021)The taxonomic diversity and metabolic activity of microbial communities in the Laptev Sea water column above and outside the methane seep field were studied. The concentrations of dissolved methane in the water column at ... -
On the relationship between climate sensitivity and modelling uncertainty
(Journal article; Peer reviewed, 2017)Climate model projections are used to investigate the potential impacts of climate change on future weather, agriculture, water resources, human health, the global economy, etc. However, climate projections have a broad ... -
One planet: one health. A call to support the initiative on a global science–policy body on chemicals and waste
(Journal article, 2022)The chemical pollution crisis severely threatens human and environmental health globally. To tackle this challenge the establishment of an overarching international science–policy body has recently been suggested. We ... -
Opinion paper about organic trace pollutants in wastewater: Toxicity assessment in a European perspective
(Journal article; Peer reviewed, 2019)This opinion paper focuses on the role of eco-toxicological tools in the assessment of possible impacts of emerging contaminants on the aquatic ecosystem, hence, on human health. Indeed, organic trace pollutants present ... -
Opportunities for seasonal forecasting to support water management outside the tropics
(Peer reviewed; Journal article, 2022)Advance warning of seasonal conditions has the potential to assist water management in planning and risk mitigation, with large potential social, economic, and ecological benefits. In this study, we explore the value of ... -
Optical water types of the Nordic Seas and adjacent areas
(Journal article; Peer reviewed, 2013)A new map of Jerlov's optical water types in the Nordic Seas and adjacent waters at 139 locations, as well as a table with statistical and geographical properties of the vertical attenuation coefficient of downward irradiance ... -
Optimizing the use of quicklime (CaO) for sea urchin management — A lab and field study
(Peer reviewed; Journal article, 2020)Mass blooms of sea urchins sometimes cause kelp forest collapses that can last for decades. Quicklime has historically been used to reverse those conditions, but the efficacy of liming has varied along latitudinal and ... -
Optimum satellite remote sensing of the marine carbonate system using empirical algorithms in the global ocean, the Greater Caribbean, the Amazon Plume and the Bay of Bengal
(Peer reviewed; Journal article, 2019)Improving our ability to monitor ocean carbonate chemistry has become a priority as the ocean continues to absorb carbon dioxide from the atmosphere. This long-term uptake is reducing the ocean pH; a process commonly known ... -
Organic Alkalinity as an Important Constituent of Total Alkalinity and the Buffering System in River-To-Coast Transition Zones
(Peer reviewed; Journal article, 2023)Organic acid-base species in the dissolved organic carbon pool have been shown to make an important contribution (i.e., organic alkalinity; OrgAlk) to the total alkalinity (TA) in many coastal systems. This study documents ... -
Organic chemicals associated with rubber are more toxic to marine algae and bacteria than those of thermoplastics
(Peer reviewed; Journal article, 2023)The current study investigated the chemical complexity of fifty plastic (36) and elastomer/rubber (14) methanol extracts from consumer products, focusing on the association with toxicity in two screening assays (bacteria ... -
Organic nitrogen steadily increasing in Norwegian rivers draining to the Skagerrak coast
(Peer reviewed; Journal article, 2020)Declining atmospheric nitrogen (N) deposition, through reduction in the direct input of inorganic N, may result in less inorganic N being leached from soils to freshwaters (dissolved inorganic N = DIN). Declining sulphur ... -
Original specimens and type localities of early described polychaete species (Annelida) from Norway, with particular attention to species described by O.F. Müller and M. Sars
(Journal article; Peer reviewed, 2014)Early descriptions of species from Norwegian waters are reviewed, with a focus on the basic requirements for reassessing their characteristics, in particular, by clarifying the status of the original material and locating ... -
Overvann i bebygde strøk - tid for å involvere innbyggerne
(Journal article; Peer reviewed, 2018)Lokal åpen overvannsdisponering (LOD) er en del av Oslo kommunes strategi for å håndtere overvann. Ved nye boligprosjekter krever kommunen at overvann håndteres på egen tomt, men det finnes ikke lignende krav i bebygde ... -
Overvåking av kransalger i kalksjøer ved Harstad/Narvik lufthavn, Evenes.
(NIVA-rapport;7323, Research report, 2018)Hensikten med oppdraget har vært å foreta undersøkelser av kransalgeforekomst og -status i Langvatn, Lavangsvatn og Kjerkvatn i 2018, samt foreslå et overvåkningsprogram for området. De tre innsjøene inngår i naturreservater ... -
Overview of Integrative Assessment of Marine Systems: The Ecosystem Approach in Practice
(Journal article; Peer reviewed, 2016)Traditional and emerging human activities are increasingly putting pressures on marine ecosystems and impacting their ability to sustain ecological and human communities. To evaluate the health status of marine ecosystems ... -
Oxidative stress potential of the herbicides bifenox and metribuzin in the microalgae Chlamydomonas reinhardtii
