Cod have annual growth rings in the bony structures in their ears. Scientists in Greenland have collected these structures for nearly a century and have made a discovery that could help avert a new fisheries collapse.
A mind-boggling array of tasks forms the underpinning of our understanding of the factors that affect the climate, both now and as the planet warms. Danes aboard the Norwegian research vessel G.O. Sars are adding to this knowledge by counting specks of zooplankton faeces.
The sweet smell of plankton envelopes researchers on deck as they haul up buckets of copepods, shrimp, algae and fish. Spring has come to the Labrador Sea. The marine science gold rush is in full swing.
The Arctic climate is entering a new state, say the scientists behind a new pan-Arctic report. But implementing the Paris Climate Agreement in full could stave off some of the biggest changes post 2050.
