The long road from Arctic science to international law
The second meeting of the Parties to the Minamata Convention on Mercury takes place this week in Switzerland. The road to the international convention took almost 15 years and is significantly influenced by Arctic research and Norwegian efforts.
Researchers use drones to photograph seaweeds: The tidal zone from a bird’s-eye view
Drones are the future for nature mapping and monitoring. They provide 1,000 times better image resolution than satellites and one million times more data points, says Kasper Hancke, marine biologist at Norwegian Institute for Water Research (NIVA).
Will climate change affect Norwegian kelp forests in a positive way?
Climate change, including acidification of the oceans, will likely affect many of the plants and animals in our sea and oceans. Fresh research results indicate that kelp could be favoured by some of the changes.
The midnight sun messes with the Arctic charr’s inner clock
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.
DNA analyses reveal secrets about the Pacific oyster
Is oyster larvae drift across the Skagerrak the cause of wild oysters great increase? New DNA analyses provide insight into the origin of the first wild Norwegian sea oyster populations.
Microplastics in the earth: A reason to worry?
While the focus to date has been on microplastics in the ocean, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes.
Are efforts against lead contamination working?
Efforts to reduce industrial emissions of lead have been ongoing for several decades. However, some of the lead comes from natural sources, so how can scientists tell if the efforts are worth while?
Kon Tiki 2 sets sail
Two balsa rafts have sailed from Lima, Peru for the Easter Island. In six weeks the expedition will return after a trip of more than 5000 nautical miles. The rafts are equipped for full scale oceanographic research and the first attempt in our time to show how ancient mariners sailed the Pacifics.
Nine of ten fulmars have plastic in their stomachs
Plastic in the form of very small particles, called ‘microplastic’, pollutes much of the marine environment. Scientists now find microplastics in the majority of samples collected from the world's oceans.
The oceans of tomorrow have floating islands
Rapid growth of the world’s population, especially in coastal regions, adds pressure on resources and land already approaching their physical limits. Scientists are designing platforms to combine industry and harbour activity with renewable energy, aquaculture and leisure.
Expanding mountain forest promotes climate warming
Birch forest is currently expanding in mountain regions because of climate warming and reduced grazing pressure. A recent study shows that increased mountain forest promotes climate warming.
The case of the vanishing pollutant
Ten years ago trout in Norway’s largest lake had the world’s highest measured levels of the environmental pollutant PBDE. Now their levels are about the same as before the sizeable discharges started in the 1990s.
