niva.no has undergone changes to start the New Year fresh. Please contact us if you are missing any information.

After NIVA was officially approved by the US Coast Guard and DNV-GL as a test facility subcontractor for ballast water treatment in March this year, NIVA’s ballast water team has worked intensively with Optimarin, a Norwegian provider of technology based on filtration and UV-treatment of ballast water. In November they had a breakthrough.

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.

On Tuesday, 27th June 2017, the Norwegian Institute for Water Research (NIVA) will open its China Office.

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.

To treat sea lice infections in aquaculture, veterinary medicines are widely used. However, these medicines may cause collateral damage.

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.

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.

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.

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?

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.

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?

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).

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.

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?

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.

It is one of the best paid seafood products and destroys kelp forests worth millions of NOK. Can sea urchin harvest be profitable?

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.

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?
