Young and thin instead of old and bulky: Researchers report on changes in Arctic sea ice
In the central Arctic the proportion of old, thick sea ice has declined significantly. Instead, the ice cover now largely consists of thin, one-year-old floes. This is one of the results that scientists of the Alfred Wegener ...
