Autonomous robots track plankton in the Arctic Ocean
Underwater robots, combined with simple instruments from 100 years ago, are helping researchers unlock the secrets of microscopic marine organisms called plankton.
Raw materials from the sea

Researchers work to promote phosphorus recovery and recycling
Here’s how Norway can limit the loss of an all-important substance, phosphorus.
Fish residues can compensate for raw materials shortages and improve our health into the bargain
More than a million tonnes of fish residues can rescue the food and cosmetic industries from raw materials shortages – and create new jobs. The key factors here are oils rich in omega-3, collagen and gelatin.
Artificial intelligence makes smarter use of seaweed and kelp
Seaweed and kelp, or macroalgae, are used in many products, and may become an even more important resource in the future. Artificial intelligence can help us avoid overusing this valuable resource.
Climate change in Greenland could cause trouble for arctic char
Greenland’s glaciers are melting and the surrounding seawater is getting warmer. How are arctic char coping with climate change? Scientists are in the process of figuring it out.
Copepods – tiny creatures that can help reduce the need for soya imports
In the sea, fish feed on species lower in the food chain. Can these same species form the basis of a new feed industry supplying the fish farming sector?
Norway will be the first in the world to approve seabed mining. Is it a good idea?
The transition to a greener, renewable economy will require large amounts of minerals, and society has to get them from somewhere. Norwegian politicians have reached an agreement approving deep sea mining, in a proposal that has reaped both cheers and frustration from scientists and activists alike. Here’s what our scientists think.
Sludge from salmon hatcheries will become a sought-after resource
Fish faeces and residual feed recovered from salmon hatcheries may soon become a sustainable product. The salmon farming sector will be crying out for a solution to the forecast ‘feed squeeze’.
Salmon that eat salmon are more environmentally friendly
We should use all parts of whole farmed salmon and keep more of the residuals here in Norway. Researchers say this will help protect the environment while ensuring salmon welfare.
How safe is your sushi?
Bacteria in raw seafood can make you sick. Seafood can also spread bacteria that are resistant to antibiotics.
Marine plastic waste can spread antimicrobial resistance
Bacteria discharged to the oceans in sewage and wastewater thrive on the biofilms that form on plastic waste. This may be leading to the somewhat unanticipated problem of antimicrobial resistance.
Professor wants to involve children in work
“A sense of community between generations will be key to ensuring sustainable coastal communities. The importance of children’s learning through work is underestimated,” says Professor Anne Trine Kjørholt.
The New Atlantis – more and more of the world is underwater
Most of our planet is underwater – and steadily more will be underwater in the years to come. What do we really know about the underwater world?
21,000 FTEs employed in the Norwegian fishing fleet
The total contribution to wealth creation from the Norwegian marine fishing fleet in 2021 was NOK 32.8 billion, including ripple effects.
Sustainability and animal welfare concern young people the most
What are people’s attitudes towards food, sustainability, new foods and food additives? Researchers have found some answers.
Could cusk fish be the new cod?
Today we think of cusk as a bycatch species of little or no value. But our test panel came to quite a different conclusion.
In the future, Norwegian salmon can be fed with locally-sourced ragworms
Researchers had the crazy idea of feeding ragworms with locally-cultivated seaweeds. The results were as gold-edged as the worms themselves – a high-quality, locally-sourced and sustainable feed for farmed salmon.
A robotic microplankton sniffer dog
The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.
Building trust in robots to measure, monitor, and regulate the ocean
A new partnership between the Centre for the 4th Industrial Revolution Ocean and the Norwegian University of Science and Technology (NTNU) has been established to establish trust in ocean data collected from autonomous underwater vehicles.
Arctic light pollution affects fish, zooplankton up to 200 metres deep
If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
More people and fewer wild fish lead to an omega-3 supply gap
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
A day in the life of a jellyfish hunter
The oceans are teeming with ever-increasing numbers of jellyfish. These squishy sea creatures can ruin fishing and discourage tourists. But one research group wants to turn this nuisance into pay dirt.
Teaching the next generation of fish farmers for the aquaculture industry
We need to know more, and teach more people, about aquaculture so we can use the ocean’s resources to the greatest extent possible while protecting the environment.
Herring larvae could benefit from an acidifying ocean
Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that’s bad news for fish, including commercially important species. But not all fish respond the same way.
