Ice blink is the white light seen on the horizon, especially on the underside of low clouds1, resulting from reflection of light off a field of ice immediately beyond.
The ice blink was used by both the Inuit and explorers looking for the Northwest Passage to help them navigate safely.[1]
The Cocteau Twins song, Iceblink Luck, is named after this phenomenon.
