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.

Ten innovative EU projects to build ocean observation systems that provide input for evidence-based management of the ocean and the Blue Economy, have joined forces in the strong cluster ‘Nourishing Blue Economy and Sharing Ocean Knowledge’. Under the lead of the EuroSea project, the group published a joint policy brief listing recommendations for sustainable ocean observation and management.

For decades in Norway, the species rich kelp forests have been grazed down by sea urchins, leaving behind nothing but naked rocks. As a result of climate change, sea urchins along parts of the Norwegian coast are now on retreat, while the same climate changes are probably the cause of the new, big threat towards the global kelp forests: the rise of turf algae.

In a time of environmental awareness, spurred on by the possibility that our world is threatened by climate change, it is important to remember that there are other anthropogenic pressures, which are also essential for addressing the protection of the marine and coastal environment. Pollution is a global, complex issue that contributes to biodiversity loss and poor environmental health and comes from the production and release of many of the synthetic chemicals that we use in our daily lives. Chemical contaminants are often underrepresented as a major contributor of environmental deterioration.

We have grown out of our premises in Oslo Science Park and will during August 2021 move to Økernveien 94. The formal change of address will take place on 16. August.

More and more rivers are regulated to serve human needs such as flood protection, transport, irrigation, hydropower generation or drinking water supply. Do altered flow dynamics affect organisms that inhabit the river bottom? And how does river flow interact with other ecosystem stressors like acidification or nutrient enrichment? A recent research project combined a flume experiment with findings from 64 regulated and unregulated river sites in Norway and Germany to find the answers.

In order to predict and manage the long-term health and status of the Otra river's salmon populations, a new study has considered acidification as part of a multiple stress combination affecting the river alongside hydropower and climate change.

New research published today in Conservation Letters finds that over half of fish stocks are below levels that would yield greater long-term catches, enhance food security and avoid overfishing. Of those fish stocks, over a third are at 80 percent below sustainable catch.

Below ice and snow, in pitch dark, Arctic charr’s circadian clock still ticks with precision. The exception comes during the darkest and brightest weeks of the year, when daily activity rhythms break down.

Researchers from the Norwegian Institute for Water Research (NIVA), in collaboration with their Chinese colleagues, recently found a new chemical compound which has evaded the attention of environmental research and regulation for several decades.

The Norwegian Institute for Water Research (NIVA), GRID-Arendal and the Institute of Marine Research (IMR) have become the pioneering founders of a new Norwegian initiative to strengthen and share national competence on ‘blue forest’ habitats.

The world’s deep ocean spans more than half the planet. Humankind needs and depends upon many of the deep ocean’s treasures, and the race is already on to exploit them.
