NASA’s research flight on Operation IceBridge captured Petermann Glacier, Greenland. It won’t be until summertime that a significant amount of melt shows up across the Greenland Ice Sheet. The image on April 16 shows part of a frozen meltwater lake while the one on April 17 shows the lake is well frozen and covered with snow again.

Greenland is the world’s largest island of which three-quarters of the land is covered by the only permanent ice sheet outside Antarctica. The Greenlandic economy is highly dependent on fishing. Fishing accounts for more than 90% of Greenland’s exports, and the shrimp and fish industry is by far the largest income earner. In 982, after finding a habitable area and settling there, the Norwegian-born Icelander Erik the Red named it “Greenland”, supposedly in the hope that the pleasant name would attract settlers.
