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.[1][2] It may subsequently become frozen into pack ice (one form of sea ice).

When you think of Antarctica, pristine white icebergs usually come to mind; probably the last thing you’d expect are humbug-like striped icebergs, with blue, green, yellow and even brown.
