Norwegian Armed Forces: A lot more ammunition than previously thought has been dumped in Norway's largest lake – missiles are tightly packed
The Norwegian Defense Research Institute has discovered significantly larger amounts of dumped ammunition in lake Mjøsa than previously thought. An area at the bottom of the lake is covered with around a thousand missiles.
Deadly heat and extreme rainfall: This is what the world will be like if the temperature rises by 3 degrees, according to researchers
“It is very likely that we will reach three degrees. I consider 1.5 and 2 degrees to be almost unattainable. Now the question is how close to three we will get,” says one Norwegian researcher.
A strong breeze and chance of storms: How we used pollen to create a wind forecast from 10,000 years ago
SHARE YOUR SCIENCE: Pollen can travel far through the air, allowing scientists who find them to trace the winds of the past. Maaike Zwier writes about her new study from South Georgia, where ancient pollen may reveal shifts in the dominating westerlies.
Rare earths: Norwegian fertilizer against a Chinese near-monopoly
Electric cars, mobile phones, wind turbines — modern technology needs metals that are almost exclusively found in China. Residues from Norwegian fertilizer production can help Europe become less dependent on a country that wants to produce more itself.
Could Isaac Newton show us the way into the Green Shift?
Climate change, loss of biodiversity, and degraded ecosystems: we're in trouble and something needs to be done. We need to change, and we know what to do. But we probably need some help on how to proceed. Maybe we can be inspired by Isaac Newton’s three laws?
On the JC2-2 cruise we are visiting the deep basins of the Arctic Ocean. The goal of my team is to conduct experiments with animals from the bottom of those basins, which means keeping deep, Arctic animals alive. If deep-sea diving is an extreme sport, then this is definitely extreme science.
The Arctic Ocean blender system
The Arctic Ocean is composed of different layers organized on the vertical, and these layers have different temperature and salinity properties. A cold and fresh surface layer caps a warm and salty layer of Atlantic Water. The heat contained at depth (about 300m) in the warm and salty Atlantic Water could melt the entire Arctic sea ice cover if it reached the surface. It does not happen because the cold surface layer caps this Atlantic layer quite well and keeps it at depth. However, in some regions, such as north of Svalbard, sea ice melts in summer even though it is -30 outside. How is that possible?
The Central Arctic Ocean: No longer the once forgotten no man’s land
Large trawlers are pulling tons of fish out of the deep Central Arctic Ocean. Our cell phones are powered with rare earth elements from the seafloor underneath the North Pole. The ice-free Arctic allows much shorter delivery time of shipped goods from the Atlantic to the Pacific. Coast guard ships dot the vast Arctic coastline and fleets of submarines survey the chilly waters. Will these scenarios soon be a reality? To some extent some of them already are.
Cracks in the cooking pot lid
The point of putting a lid on a cooking pot is to prevent the transfer of heat and moisture between the boiling contents and the air above. When you remove the lid from a boiling pot, heat and water vapour flow upward into the air, along with chemical compounds filling your kitchen with the (hopefully) promising smells of an upcoming meal.
