Marine heatwaves are becoming more frequent and intense due to climate change. This has wide-ranging impacts for ocean-human interactions, researchers find.

On Thursday afternoon, the research vessel G.O. Sars found cable that was missing from Lofoten-Vesterålen sea observatory (LoVe).

The Lofoten–Vesterålen Ocean Observatory (LoVe) is currently out of service. This is due to extensive damage to the outer circuit of the observatory, and it will take time for the full system to return to normal operations.

Scientists call for ocean-based action to tackle the climate crisis.

…and ended up at the same spot, at the same time where the scientists had tagged it the previous year.

The research vessel has been in Norway since March 2020. Now it is returning to Africa – with five first-time crew on board.

Fish as a source of important micronutrients deserves increased attention in discussions on food and nutrition policy.

Plastic pollution readily crosses boundaries between countries and ecosystems. Research and monitoring also requires a holistic approach and a global perspective, argues initiator Michael Bank.

Nutritionists often say that young women in Norway consume too little iodine. Why? And what has it got to do with the sea?

New evidence that humpbacks sing outside of their tropical breeding grounds. 

In our new series "Seafood for land crabs", you will get to know your dinner better! We take a closer look at what useful and important nutrients you should get through your diet, how they work and why you need them. We also look at the less pleasant substances, the ones that we should not get too much of.  

Insect farming for fish-feed production offers interesting opportunities in aquaculture, but it also raises new challenges for food and feed safety testing. Researchers have now developed and tested new methods for detecting and tracing prohibited ingredients in insect meal.

New marine resources such as mesopelagic fish may play a larger role in future food systems. Researchers are now studying what this could mean for our health.

IMR researchers have found a wreck off Bodø that they assume must be DS Malmberget. After 108 years, we may be close to solving the mystery of this ship, which disappeared in a storm with 43 people on board. 

“The common hand sanitizers work only on certain types of virus, including coronaviruses”, explains Mette Myrmel, a virologist at the Institute of Marine Research.

Historical and contemporary samples of Norwegian and Canadian cod show that the fish’s genome has remained stable over time.

For thousands of years, seafarers have lived in fear of dangerous monsters living in the ocean. We’ll guide you through their treacherous waters.

This is good news for both fishers and fish stocks.

… and why this creates a challenge for land-based fish farming.
