Report: Area multi-year ice in the Arctic has increased

In late March, the Centre said that the maximum area of the Arctic sea ice this year reached March 7: 14,640,000 square kilometers. However, this maximum is found to be equal to the lowest maximum on record, recorded in 2006.

According to some data, the average area of ice in March was 14.56 million square kilometers lower value was recorded only in 2006.

"In view of the data for 2011, the average area of ice in March decreased over the decade by 2.7%," said.

After March 7 ice area has been gradually reduced. Although in some periods it was growing again, no maximum was exceeded once.

Every year at the beginning of the melt season snow scientists measure the age of the ice in different regions of the Arctic, using data from satellites and buoys. Old ice which has survived several summers are usually thicker, while the fresh ice thinner and more likely to melt in the summer. In recent decades, the spring ice cover growing continuously share of young and thin ice.

"This year, the number of old and thick ice has increased, although it remains well below the average for the period from 1979 to 2000. Data for the third week of March showed an increase compared with the last years the share of the ice at the age of one to two years and over two years, " Meteorologists reported.

"However, they note, amount of old ice remains much lower than in the mid-1980s, and there is little ice older than four years. "

Furthermore, the very old and the distribution of new ice in the Arctic is unusual compared to the 20th anniversary to the 2000 year. Winds and currents have led to the old ice tongue that extends from the north of Canada, through the Beaufort Sea and Chukchi Sea.

Similar language appeared in March 2010 and almost completely melted over the summer, RIA "Novosti".

According to the newspaper VIEW, due to the large number of chemicals in the atmosphere in 2011, the thickness of the ozone layer over the Arctic has decreased to record levels, said Tuesday the UN World Meteorological Organization.
