The CERAD Centre for Environmental Radioactivity (CERAD CoE) was established by the Research Council of Norway to provide new scientific knowledge and tools for better protection of people and the environment from harmful effects of radiation (2013-2023).

It is one of the best paid seafood products and destroys kelp forests worth millions of NOK. Can sea urchin harvest be profitable?

May 2015, Kristiansand, Norway. Two researchers in a boat loaded with thousands of blue mussels, collected from a mussel farm in Lillesand. The boat heads out the Kristiansand fjord, and the researchers deploy the blue mussels in the sea. Why are they doing this?

Despite having increased human wellbeing in the past, intense modifications by multiple and interacting pressures have degraded ecosystems and the sustainability of their goods and services. For ecosystem restoration to deliver on multiple environmental and societal targets, the process of restoration must be redesigned to create a unified and scale-dependent approach that integrates natural and social sciences as well as the broader restoration community.

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.

To facilitate research on land-ocean interactions the Norwegian Institute for Water Research (NIVA), with financial support from the Norwegian Ministry of Climate and Environment, has established a new infrastructure in a river-fjord system (Storelva river – Sandnesfjord) close to Tvedestrand in Aust-Agder County.

Since the millennium, water masses in the Skagerrak sea have become sufficiently warm for Pacific oyster larvae to survive the journey to Norway from the coasts of Sweden and Denmark. In the same period, the occurrence of wild oysters has exploded along the Norwegian coast. Is oyster larvae drift across the Skagerrak the cause of this great increase? New DNA analyses provide insight into the origin of the first wild Norwegian sea oyster populations.

Passive sampling is a valuable technique for monitoring concentration levels of hydrophobic persistent organic pollutants (POPs) in the marine environment. New guidelines for the determination of partition coefficients between passive samplers and water have recently become available in new report.

Efforts to reduce industrial emissions of lead have been ongoing for several decades. The near-global phase-out of leaded automobile gasoline has showed decreases in environmental lead contamination. A reasonable expectation is that industrial lead concentrations have also measurably decreased in the Southern Ocean. Since lead also has natural sources, a group of scientists decided to examine the relative importance of anthropogenic lead in the Amundsen Sea, a shelf region of West Antarctica, in the first measurements of this sort.

Researchers tracked the northern-most freshwater fish over an entire year with surprising results.

For the first time, biologists from Albania and Macedonia have worked together to improve ecological status in Lake Ohrid.

Birch forest is currently expanding in mountain regions and far north. This trend is related to climate warming and reduced grazing pressure. A recent study shows that increased birch forest cover at high elevations promotes climate warming.

The Deepwater Horizon oil spill constituted an ecosystem-level injury in the northern Gulf of Mexico. Much oil spread at 1100–1300 m depth, contaminating and affecting deepwater habitats. In this review, NIVA and American partners summarize the environmental research literature on the accident.
