According to a new research report, most plastic fragments end up on the ocean floor.
Fish and aquaculture
Currents in the ocean and fjords spread viruses that are killing large numbers of farmed salmon. Where should fish farms be built? And should they all be in use at the same time? Researchers now know more about how to limit the virus problem.
The mysteries below the ocean’s surface have triggered human exploration and imagination for centuries. New marine robotics now make it possible to explore what goes on in the ocean depths.
We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.
Trondheim: Norwegian researchers believe that it will be possible to make environmentally-friendly snow at above-zero temperatures. Now they have the backing of Europe and the skiing industry in their bid to save the sport from climate change.
The condition of the water in salmon hatcheries can tell us a great deal about when and why outbreaks of disease occur. Now, SINTEF researchers are about to expose the water’s secrets, both to prevent suffering in fish and to save the aquaculture industry a great deal of money.
Establishment of the Norwegian Centre for Plankton Technology has yet to be completed, but there has nevertheless been high levels of interest from both industry and research.
Robotics technology is making inroads into the aquaculture sector, making it possible to regulate facilities from onshore.
Science has made great strides since Svante Arrhenius, the Swedish Nobel Laureate who in 1896 first determined that carbon dioxide from human activity could warm the planet. The same progress hasn’t been made in increasing the number of women in the sciences.
The close relationship between SINTEF and NTNU has catapulted the university to a number one ranking among the world’s universities when it comes to publishing in partnership with a single industry collaborator.
The Japanese eat one in ten of the world’s fish, and 80 per cent of the planet’s prized —and critically threatened — Bluefin tuna. Tuna aquaculture pioneered at Kindai University in Japan offers hope for both fish lovers and the fish.
Every year 340,000 tonnes of usable whitefish by-product are discarded into the sea. But the fisheries industry has now identified ways of halting this practice.
Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.
Big Data means that professional fishermen will soon be getting their own decision-making tool. It will tell them where fish shoals are located, and how their vessels can be operated as economically as possible.
Fish can adapt their metabolisms to cope with warmer ocean temperatures, but not necessarily with extreme heat.
Representatives from Japanese and Norwegian universities, research institutions, government agencies and industries interested in polar issues will gather in Tokyo in early June to present research results and build partnerships.
Starting today, Hiroshito Matsumoto will work from a base in Toyko on behalf of NTNU and the University of Bergen to build new research partnerships between Japan and Norway.
Overfishing is part of the climate problem. There is little doubt that we need to change our habits, but what exactly do we need to do, and why is it so difficult?
The Kon-Tiki2 expedition aims to both reinforce and challenge Heyerdahl’s theories – and NTNU will gather unique research material from the major oceans that the expedition crosses
Every year, an estimated 8 million metric tons of plastic waste blows, falls or flows into the world’s oceans. Earlier this autumn, participants in the annual Svalbard Course plucked up 512 kg of the stuff from just one beach in two hours.
The science program Daily Planet has 8 million viewers. During the last week of June, a production crew from the program filmed an expedition to look for a plane wreck from the Second World War that is located on the bottom of Trondheim Fjord.
