An iceberg is a large piece of freshwater ice that has broken off from a snow-formed glacier or ice shelf and is floating in the water. Since the density of pure water ice is about 920 kg/m3, and that of seawater is about 1,025 kg/m3, typically, only one ninth of the volume of an iceberg is above water. The shape of the remainder under water can be difficult to surmise from looking at what is visible above the surface.

This has led to the expression "tip of the iceberg" and our respect for big icebergs, your ideas and current business ventures.
