NIVA approved by US Coast Guard as subcontracted test facility for Lloyd’s Register
Since 26th of January 2017, NIVA can provide US Coast Guard testing to the English Class Society Lloyd’s Register as approved subcontracted test facility, in addition to the Norwegian Class Society DNV-GL.
NIVA opens office in China
On Tuesday, 27th June 2017, the Norwegian Institute for Water Research (NIVA) will open its China Office.
Microplastics in agricultural soils: A reason to worry?
Microplastics are increasingly seen as an environmental problem of global proportions. While the focus to date has been on microplastics in the ocean and their effects on marine life, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes from application of sewage sludge.
Anti-Sea lice drugs may pose hazard to non-target crustaceans
To treat sea lice infections in aquaculture, veterinary medicines are widely used. However, these medicines may cause collateral damage.
The first lead measurements from the Amundsen Sea
Efforts to reduce industrial emissions of lead have been ongoing for several decades. The near-global phase-out of leaded automobile gasoline has showed decreases in environmental lead contamination. A reasonable expectation is that industrial lead concentrations have also measurably decreased in the Southern Ocean. Since lead also has natural sources, a group of scientists decided to examine the relative importance of anthropogenic lead in the Amundsen Sea, a shelf region of West Antarctica, in the first measurements of this sort.
Strengthening passive sampling of nonpolar chemicals
Passive sampling is a valuable technique for monitoring concentration levels of hydrophobic persistent organic pollutants (POPs) in the marine environment. New guidelines for the determination of partition coefficients between passive samplers and water have recently become available in new report.
DNA analyses reveal secrets about the Pacific oyster
Since the millennium, water masses in the Skagerrak sea have become sufficiently warm for Pacific oyster larvae to survive the journey to Norway from the coasts of Sweden and Denmark. In the same period, the occurrence of wild oysters has exploded along the Norwegian coast. Is oyster larvae drift across the Skagerrak the cause of this great increase? New DNA analyses provide insight into the origin of the first wild Norwegian sea oyster populations.
Caged blue mussels as environmental detectives
May 2015, Kristiansand, Norway. Two researchers in a boat loaded with thousands of blue mussels, collected from a mussel farm in Lillesand. The boat heads out the Kristiansand fjord, and the researchers deploy the blue mussels in the sea. Why are they doing this?
Pesticide cocktails cause environmental risk
The risk assessment of pesticide is usually performed on individual compounds. The combination of these environmental chemicals in complex environmental mixtures may give rise to unexpected and unwanted effects. Researchers at NIVA have identified that mixtures of pesticides in Norway may indeed represent a risk to aquatic organisms.
Wildlife in the ditches need a detox cure
When it´s raining on the roads, slops of road dust and contaminants drain into the road trenches. What does it do to wildlife living by the road?
CERAD
The CERAD Centre for Environmental Radioactivity (CERAD CoE) was established by the Research Council of Norway to provide new scientific knowledge and tools for better protection of people and the environment from harmful effects of radiation (2013-2023).
95% of Fulmars in the North Sea Had Plastic in Their Stomachs
Plastic in the form of very small particles, so-called ‘microplastic’, pollutes much of the marine environment. Scientists find microplastics in the majority of samples collected from the world's oceans.
Climate adaption of water management
EU Water Framework Directive gives specific goals that Member States are obliged to reach. But in a changing climate, with increasingly frequent and extreme weather and climate events, how is water management effectuated?
Monitoring alien marine species
NIVA have in a new study examined the occurrence of marine alien species in the Oslo fjord to develop a cost-effective method for early warning of new alien species, and of monitoring the spread and ecological effects of some selected alien species.
Mercury in Cod
The levels of mercury in the Oslofjord cod has increased over the last 30 years, despite reduced emissions of this toxic element. In the same period, the average size of sampled cod has increased. Are the elevated levels of mercury simply a result of larger cod?
Sea urchins: from pest to plate
It is one of the best paid seafood products and destroys kelp forests worth millions of NOK. Can sea urchin harvest be profitable?
The Environmental Specimen Bank – a time capsule for the future
Crunching sounds break the silence when a steel knife cuts loose the top of a trout´s head, exposing the fish brain. Let´s join a guided tour in the Environmental Specimen Bank in Oslo.
Stor torsk har meir kvikksølv
Dei siste tretti åra har konsentrasjonen av kvikksølv auka i torsken i Oslofjorden, jamvel om utsleppa av miljøgifta er reduserte. Samstundes er òg gjennomsnittstorsken forskarane har teke prøvar av frå fjorden vorten større. Er dei auka kvikksølvnivåa rett og slett eit resultat av at torsken har vakse?
