The long road from Arctic science to international law

The road to the Minamata Convention on mercury took almost 15 years and has been significantly influenced by Arctic research and Norwegian efforts. Why and in what way did Arctic research play such a significant role in this road towards the convention?
Researchers use drones to photograph seaweeds

Drones are the future for nature mapping and monitoring. – Compared to satellite pictures, drone images provide 1,000 times better image resolution and one million times more data points, says Kasper Hancke, marine biologist at NIVA.
Pollutant-ban has made snails healthy again

The environmental pollutant TBT can mimic hormones to the extent that it sterilizes female snails and make them grow non-functional penises and vas deferens. But for the first time since monitoring started up in 1991 and the total ban of TBT entered force in 2008, only fertile dogwhelk have been found along the Norwegian coastline.

A sea lice free salmon prison

In October 2018, the first salmon were “imprisoned” in a brand new fish production prototype in Trøndelag, Norway. With a rigid steel construction and a water current generator included, the new fish cage Aquatraz will both prevent fish escapes and keep the fish in shape, while researchers from the Norwegian Institute for Water Research (NIVA) are monitoring the sea lice and water quality in the cage.

Improved faunal status at the soft bottom in Skagerrak

Reductions of nutrients have led to a greater species richness at the seafloor in the Skagerrak after 1990. But warmer winter temperatures and increased river runoff might be the new challenges for the animal life at the soft bottom.
