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.

NIVA has assessed the environmental status of macroalgae communities in Sognefjorden, Norway. The findings show there is reason for concern.

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.

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.

The International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM Convention) requires ships to manage their ballast water to remove, render harmless, or avoid the uptake or discharge of aquatic organisms and pathogens within ballast water and sediments. The convention entered into force September 8th 2017.

What goes in must come out, no matter whether you it is eaten or snorted For the first time, a NIVA led research project reveals the truth of European illicit drug use.

The greatest scientific achievements have always been the most humane and the most aesthetically attractive, conveying that sense of beauty and elegance which is the essence of science at its most successful. Since 2010, Norecopa has awarded a prize for outstanding efforts to advance "the 3Rs" - Replacement, Reduction & Refinement - in connection with animal research. This year’s award has been awarded Adam Lillicrap, Research manager at the Norwegian Institute for Water Research (NIVA).

The latest findings from the largest European project in the emerging science of wastewater analysis are presented December 13th by the Europe-wide SCORE group, in association with the EU drugs agency (EMCDDA). The project analyzed wastewater in over 50 European cities in 18 European countries in March 2016 to explore the drug-taking behaviors of their inhabitants.

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.

As a result of Myanmar's democratization process in recent years, Norway has started collaboration on nature and water resource management with Myanmar. NIVA has played a central role in the work.

Fragmented environmental legislation, vertical and horizontal inconsistencies, and a weak rule of law highly affect our pathway towards a sustainable development of our marine resources and environment. A recent seminar gathered experts to discuss the effects of fragmented environmental law, shared experiences from different areas of marine and coastal environmental and natural resources law and from selected European countries, and discussed potential avenues to tackle identified challenges.

After 114 days at sea, in one of the strongest El Niño years recorded, the Kon-Tiki 2 decided to end the expedition in the South Pacific. Large sets of unique data on climate change and pollution will now be analyzed.

On December 2nd 2016, the Coast Guard Marine Safety Center issued the first U.S. Coast Guard Ballast Water Management System (BWMS) Type Approval Certificate to Norwegian manufacturer Optimarin AS after a detailed review of the type approval application determined the system met the requirements. The system has been tested in close cooperation with NIVA.

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.

Researchers from Aarhus University have measured a new world record: Small ice algae on the underside of the Arctic sea ice live and grow at a light level corresponding to only 0.02% of the light at the surface of the ice. Algae are the primary component of the Arctic food web and produce food far earlier in the year than previously thought.

Pollution levels in many Chinese lakes have declined somewhat from high levels in the past decade, helped by billion-dollar investments in urban sewers and waste water treatment.

At the Aurora hydrothermal vent field, 82.5N, the HACON project successfully sampled rocks, fluids, sediments and fauna to better understand the functioning of the deep Arctic Ocean.
