Unusual algae growing in the ice of the Arctic, not only to paint it in red or pink, but also greatly contribute to its melting. Still, the threat from these algae to the environment underestimated, is convinced which conducted the study, the team of specialists under the leadership of Stefanie Lutz from the Helmholtz Centre in Potsdam.
Still “flowering” of snow and ice, first discovered by a number of scholars early in the century, believed in the first place is not the cause but the consequence of its gradual transformation into the water — in the melted snow unicellular algae begin to proliferate. However, in the new study, experts have paid special attention to the fact that by itself, the loss of his snow white leads to the fact that he is worse than reflect sunlight, causing heats up faster and, as a consequence, melting.
Specialists do not tend to think of algae as the primary cause of melting Arctic ice, however, believe that bloom further accelerates this already occurring faster than we would like, process. In the future, scientists hope to study the effects of algal blooms in the thickness of the ice even further.
The experts published their study in the journal Nature Communications.
In March, the American experts from NASA and the National center for the study of snow and ice cover the Ground stated that the area of Arctic sea ice in 2016 was the lowest for the season in the entire history of observations, and a similar record is recorded for the second year in a row. Earlier, in his annual report the National oceanic and atmospheric administration, the lead scientist of the organization Richard Spinrad noted that the air temperature in the Arctic rose to maximum values, at least since 1900.Related posts:
