West Antarctic Ice Sheet section

Wallpaper Description:

A section of the West Antarctic Ice Sheet with mountains poking through, viewed from a window of a NASA Operation IceBridge airplane on October 28, 2016, in flight over Antarctica. NASA's Operation IceBridge has been studying how polar ice has evolved over the past eight years and was flying a set of 12-hour research flights over west Antarctica at the start of the melt season. Researchers have used the IceBridge data to observe that the West Antarctic Ice Sheet may be in a state of irreversible decline directly contributing to rising sea levels.
