In the Arctic, scientists have identified a new flow of warm, salty water from the Atlantic, stretching for more than 1,000 km. It passes through the Barents and Kara Seas and affects seasonal changes in sea ice.
The current was named after the research vessel Akademik Mstislav Keldysh. It was not easy to detect: isolated stretches of unusually warm, salty water had been observed before, but it was not clear whether they formed a single current. An analysis of data from 25 expeditions between 1995 and 2024 made it possible to see the overall picture. It turned out that the current exists year-round and carries Atlantic heat far to the east.
