January 24. British Geophysics told about the huge pool of fresh water, which they found in the western Arctic Ocean. If over time the flow ENTERED entire amount in the North Atlantic, Europe is waiting for a serious climate change, says BBC.
The growing accumulation of atypical for the ocean of fresh water has reached a volume of about 8000 cubic kilometers. Fueled by the circulation of the Beaufort, it is only since 2002 has risen above the sea level by 15 centimeters.
Researchers from University College London (University College London) said that strong wind swirled flow clockwise, causing the water to collect in one place. As a result, in the center of the Beaufort gyre growing bulge.
Especially a lot of fresh water began to arrive in the region at the beginning of zero's (the researchers analyzed data collected from 1995 to 2010) — an increase of about 2 centimeters per year.
Measurements were made satellites of the European Space Agency (ESA), which can determine the level of the water, even if it is covered by ice. The fact that the desalinated water gradually, described research buoys and water samples taken directly in the cycle of Beaufort. Scientists believe that fresh water comes from the rivers of Eurasia and Russia, flowing into the Arctic Ocean.
Wind and currents carry the water in the ocean, while the cycle of not driving it in his "arms." Preliminary estimates indicate that about 10% of the fresh water in the Arctic has accumulated in this basin.
British scientists concerned about the future of this cluster. Computer modeling indicates the unpleasant consequences that may arise if the wind changes its direction and all that fresh water will stop spinning.
In this case, it will disperse across the Arctic Ocean, and may even go to the North Atlantic, violating prevailing currents there. All of this will affect the climate of Europe is warm enough thing of the past winter, the temperature drops to a typical value for this latitude.
Geophysicists believe this scenario is real, since the accumulation of water in the cycle occurred not constant, but increased in the second half of the observation period. Ocean ice cover thins and thins out, which may lead to a change in the relationship between the winds and waters of the ocean.
Ice and icebergs can now move more freely, wind through them can mix the water very differently, the researchers report in an article published in the journal Nature Geoscience. In this case, much depends on whether the form is in the debris of the water ice and under the surface of the ocean.
Researchers are concerned that if from the depths with this stirring will be raised over the warm water, it can further accelerate the melting of the ice on the surface. Now it is not able to influence the surface water as separate from the less dense layers of cold water.
But while all this is just speculation and conclusions computer models. Britons continue to monitor the polar regions and try to predict the likelihood of certain scenarios.
"We are going to measure not only the thickness of the ice, but the water level below them. Help us in this satellite CryoSat-2, which can observe the entire Arctic Ocean "- sums up Lekson Seymour (Seymour Laxon), Director of the polar observation and modeling (CPOM).
