Researchers use drones to photograph seaweeds

Drones are the future for nature mapping and monitoring. – Compared to satellite pictures, drone images provide 1,000 times better image resolution and one million times more data points, says Kasper Hancke, marine biologist at NIVA.

Report: Precence of microplastic in Norwegian drinking water are close to zero

There are very low levels of microplastic in the water from Norwegian waterworks, according to a report conducted by Norwegian Water. The Norwegian Institute of Public Health concludes that this does not pose any health risk. The Norwegian Institute of Water Research (NIVA) has carried out the analyzes and the scientific work.

Turf algae growth in the Sognefjord

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

Measuring microplastics in blue mussels

Many different methods have been developed to monitor microplastics, although the lack of standardisation limits comparability. It is vital to carry out standardised monitoring to acquire a baseline understanding of microplastic contamination in the Norwegian environment. A new project aimed to identify suitable methods for monitoring microplastics in blue mussels and sediments - with sampling stations around the coast of Norway.

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.

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.

Does size matter? Bigger cod contains more mercury

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?
