Images of Melt: Earth's Vanishing Ice
The midnight sun glows off an iceberg in Disko Bay, Greenland. Icebergs calving into the sea are a major source of Greenland's ice loss.
A stream of meltwater flows across the ice surface in Greenland.
Meltwater creates a 60-foot deep (18.2 meter) canyon in the polar ice sheet.
This canyon drained a large meltwater lake on the surface of the ice into a moulin, or under-ice channel that flows to the bottom of the ice sheet.
Supraglacial lakes like this one (which is about 0.75 miles in diameter) dot the surface of the Greenland ice sheet during the summer seasonal melt.
A moulin dips into the ice sheet, channeling water to the base of the ice, where a network of underground springs route it to the sea.
