Scientists of the St. Petersburg branch of the Institute of Oceanology, RAS began to map anomalous Maritime zones of the Arctic, where there are internal waves up to ten metres due to the active mixing of warm and cold water, according to “Izvestia”.
Main researcher of the laboratory of geophysical boundary layers of the St. Petersburg branch of the Institute of Oceanology of RAS Alexei Zimin explained that before scientists have a difficult task, but it can be done, having elevation data of internal waves. Get them with radar from space, which make high-quality images regardless of the time of day and weather conditions.
In the course of the observations obtained a set of locations with a high chance of breaking the bottom. These areas are near the confluence of major rivers (Pechora, Ob, Yenisei, Lena and others), the depth up to 100 meters, the soil is mostly sandy.
The map will help the Russian companies for the extraction of hydrocarbons on the shelf to build in safe places. In addition, in these zones actively collects fish. The acquired knowledge also can theoretically use the submarine as interference for transmission of an acoustic signal due to the internal unrest of the water make the submarine briefly invisible to radar.
