Yearly Antarctic Sea Ice Minima from 1979 through 2008

This visualization shows Antarctic sea ice minima from 1979 through 2008. Near the end of each southern hemisphere summer (usually in February), the Antarctic sea ice cover reaches its minimum extent and what is left is called the perennial ice cover which consists mainly of thick multi-year ice floes.
