Iceberg

An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. It may subsequently become frozen into pack ice (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice.

Famous quotes containing the word iceberg:

“As the shade went up
And the ambulance came crashing through the dust
Of the new day, the moon and the sun and the stars,
And the iceberg slowly sank
In the volcano and the sea ran far away
Yellow over the hot sand, green as the green trees.”
—John Ashbery (b. 1927)
