#ARCTIC. #SIBERIA. THIS IS TAIMYR. Russian scientists have discovered a new current in the St. Anna trough that accelerates the melting of sea ice in summer and slows its appearance in winter. The deep-water trough is located in the northern part of the Kara sea on the border with the Barents sea and is considered the key region where the flow of heat from the North Atlantic to the Arctic is formed.
The current from the northern tip of Novaya Zemlya goes northward along the eastern slope of the through. This was reported in the Russian Science Foundation. In addition, the researchers found a stationary cyclic eddy at intermediate depths in the northern part of the trench – it holds most of the Atlantic waters and weakens the heat flow further into the Eastern and Central Arctic. The information obtained will help to more accurately predict the consequences of climate change in the Arctic.
The authors of the work emphasize that the ice reduction in the Arctic affects all ecosystems and the behavior of animals, in particular polar bears, economic activity in the region, mining and the Northern Sea Route development.
The study results are published in the Frontiers in Marine Science journal. The work was attended by employees of the Institute of Oceanology named after P.P. Shirshov RAS, Moscow Institute of Physics and Technology, Marine Hydrophysical Institute RAS, Russian State Hydrometeorological University and Pacific Oceanological Institute named after V.I. Ilyichev FEB RAS.
Previously, scientists took samples of colored snow in the Arctic, told where microplastics come from in Arctic waters, and also created a new method for studying glaciers.
