Blue ice brightens up Antarctica in the summer
Today’s Video of the Day from the U.S. Geological Survey (USGS) shows bright blue glacial ice that is visible across the Queen Fabiola Mountains of Antarctica in the summertime.
The textured turquoise ice forms when air bubbles are forced out of compressed snow and form layers.
According to the USGS, the ice appears blue as a result of the absorption of solar radiation at yellow and red wavelengths.
The image was captured on February 18, 2018 by Landsat 8.
