"description": "Data may encapsulate the events of a single second or many years; it may span a small patch of Earth or entire systems of suns and planets. Visualizing data within its natural environment maximizes the potential for learning and discovery. Scientific visualization can clarify data’s relationships in time and space.
In this visualization, the issue of the declining sea ice near the North Pole is set in its natural configuration. An analysis of the age of the Arctic sea ice indicates that it traditionally became older while circulating in the Beaufort Sea north of Alaska and was then primarily lost in the warmer regions along the eastern coast of Greenland. In recent years, however, warmer water in the Beaufort Sea, possibly from the Bering Strait, often melts away the sea ice in the summer before it can get older.",

Perennial ice may have a life-span of nine years or more and represents the thickest component of the sea ice; perennial ice can grow up to four meters thick. By contrast, first year ice that grows during a single winter is generally at most two meters thick.Below is an animation of the weekly sea ice age between 1984 and 2016. The animation shows the seasonal variability of the ice, growing in the Arctic winter and melting in the summer. In addition, this also shows the changes from year to year, depicting the age of the sea ice in different colors. Younger sea ice, or first-year ice, is shown in a dark shade of blue while the ice that is four years old or older is shown as white. A color scale identifies the age of the intermediary years.A graph in the lower, right corner the quantifies the change over time by showing the area in millions of square kilometers covered by each age category of perennial sea ice. This graph also includes a memory bar - the green line that here represents the current maximum value seen thus far in the animation for the particular week displayed. For example, when showing the first week in September, the memory bar will show the maximum value seen for all prior years' first week of September since the beginning of the animation (January 1, 1984).Correction: The original release on 10/28/2016 incorrectly labeled the oldest category on the graph as \"5+\". This was corrected to read \"4+\" on 10/30/2016. || ",
