This map shows the average concentration of Arctic sea ice for November 2016. Opaque white areas indicate the greatest concentration, and dark blue areas are open water. All icy areas pictured here have an ice concentration of at least 15 percent (the minimum at which space-based measurements give a reliable measure), and cover a total area that scientists refer to as the “ice extent.” NASA Earth Observatory images by Joshua Stevens, using data from the National Snow and Ice Data Center.
