Arctic Sea Ice Animation
Arctic Sea Ice

A thick chunk of Arctic sea ice the size of two states has disappeared. Is it global warming or normal causes?

This animation shows daily changes in Arctic sea ice distribution observed by the NASA SeaWinds scatterometer aboard the QuikSCAT satellite. The time period of this animation is from 1 November 2006 to 31 March 2007. The white color represents perennial sea ice, cyan is for mixed ice, turquoise for seasonal ice, red for melt area on ice, brown for land, blue for open ocean, and dark blue for invalid or missing data.
