Annual Arctic Sea Ice Minimum 1979-2018 with Area Graph

Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. This graph displays the area of the minimum sea ice coverage each year from 1979 through 2018. In 2018, the Arctic minimum sea ice covered an area of 4.15 million square kilometers.

This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2018 as derived from passive microwave data. A graph overlay shows the area in million square kilometers for each year's minimum day. The date shown in the upper right corner indicates the current year being displayed.
