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. Icebergs generally range from 1 to 75 metres  above sea level and weigh 100,000 to 200,000 metric tons. The largest known iceberg in the North Atlantic was 168 metres  above sea level, reported by the USCG icebreaker East Wind in 1958, making it the height of a 55-story building.  Source
