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
(Journal article; Peer reviewed, 2019)The widespread presence of herbicides in the aquatic environment has raised awareness about the need to develop further in depth ecotoxicological risk assessments, more specifically on potential effects on photosynthetic ... -
Oxygen dynamics in a boreal lake responds to long-term changes in climate, ice phenology, and DOC inputs
(Journal article; Peer reviewed, 2015)Boreal lakes are impacted by climate change, reduced acid deposition, and changing loads of dissolved organic carbon (DOC) from catchments. We explored, using the process-based lake model MyLake, how changes in these ... -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
(Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ... -
Parallelism in thermal growth response in otoliths and scales of brown trout (Salmo trutta L.) from alpine lakes independent of genetic background
(Journal article; Peer reviewed, 2017)Low density in natural populations of salmonids has predominantly been managed by stocking of non‐native conspecifics. Due partly to domestication, introduced non‐native fish may be maladapted under natural conditions. ... -
Parameter sensitivity analysis of a 1-D cold region lake model for land-surface schemes
(Journal article; Peer reviewed, 2017)Lakes might be sentinels of climate change, but the uncertainty in their main feedback to the atmosphere – heat-exchange fluxes – is often not considered within climate models. Additionally, these fluxes are seldom measured, ... -
Parameters structuring macrophyte communities in rivers and lakes - Results from a case study in North-Central Poland
(Journal article; Peer reviewed, 2014) -
Partitioning of persistent hydrophobic contaminants to different storage lipid classes
(Peer reviewed; Journal article, 2021)Lipids generally represent the major matrix contributing to the absorptive capacity for hydrophobic organic contaminants in aquatic ecosystems. The aim of the present study was to determine whether contaminants partition ... -
Passive sampling and benchmarking to rank HOC levels in the aquatic environment
(Peer reviewed; Journal article, 2021)The identification and prioritisation of water bodies presenting elevated levels of anthropogenic chemicals is a key aspect of environmental monitoring programmes. Albeit this is challenging owing to geographical scales, ... -
Passive Sampling Helps the Appraisal of Contaminant Bioaccumulation in Norwegian Fish Used for Regulatory Chemical Monitoring
(Peer reviewed; Journal article, 2022)Hexachlorobenzene (HCB), listed on the Stockholm Convention on persistent organic pollutants and regulated as a hazardous priority pollutant by the Water Framework Directive (WFD), is ubiquitously distributed in the ... -
Passive sampling methods for contaminated sediments: risk assessment and management
(Journal article; Peer reviewed, 2013)This paper details how activity-based passive sampling methods (PSMs), which provide information on bioavailability in terms of freely dissolved contaminant concentrations (Cfree), can be used to better inform risk management ... -
Passive sampling of wastewater as a tool for the long-term monitoring of community exposure: Illicit and prescription drug trends as a proof of concept
(Journal article; Peer reviewed, 2017)A passive sampling device, the Polar Organic Chemical Integrative Sampler (POCIS), was calibrated in-situ over a 4-week period in Oslo (Norway) for 10 illicit drugs and pharmaceuticals with the goal of developing an approach ... -
