Sea Ice Area

Arctic Sea Ice Area Maximum/Minimum Day, plus Days Spent below 15-3 km2 1979 - 2015 (including Decadal Averages)

This graph divides each calendar year into 12 "slices", one for each month. Arctic sea ice area is plotted for each day of the year,
moving clockwise around the graph and taking one full year to complete a circuit. The area of sea covered by ice on a particular
day is represented by that plot's distance from the center of the graph; as shown by the vertical axis, more ice area places the plot
farther from the center of the graph, while less ice area places the plot closer to the center. Past years are represented by thin gray
lines, while decadal averages and the current year are thicker and color-coded as detailed in the legend.
