On the return of the Polarstern vessel of the Alfred Wegener Institute (AWI) for Polar and Marine Research in the German-based Helmholtz Association, scientists reported that organisms found in the Atlantic region of the Southern Ocean were not adapting quickly to changes in the environment.
The European Space Agency, the UN’S World Meteorological Organization, and the Alfred Wegener Institute for Polar and Marine Research are among the leading authorities reporting a record depletion of the ozone layer over the Arctic.
According to the WMO, “depletion of the ozone layer … has reached an unprecedented level over the Arctic this spring because of the continuing presence of ozone-depleting substances…”
NASA’s Goddard Space Flight Center has produced this map and the following video representing the ozone loss over the Arctic over the beginning of 2010 and 2011. They show the concentrations of ozone over the Arctic as monitored by the Ozone Monitoring Instrument (OMI) onboard NASA’s Aura satellite.
Cooler temperatures in the ozone layer above the Arctic have recently caused a dramatic drop in ozone levels, suggesting that the region is in for a record loss of the trace gas that protects the planet’s surface from ultraviolet radiation from the sun.
