a relatively small iceberg, only seven meters above water; meaning there are about 60 meters under water!
taken off the coast of Greenland.
Because the density of pure ice is about 920 kg/m3 (57 lb/cu ft), and that of seawater about 1,025 kg/m3 (64 lb/cu ft), typically about one-tenth of the volume of an iceberg is above water (which follows from Archimedes's Principle of buoyancy). The contour of the underwater portion can be difficult to judge by looking at the portion above the surface. Icebergs are often compared in size to the area of Manhattan.
Icebergs may reach a height of more than 100 metres (300 ft) above the sea surface, and have mass ranging from about 100,000 tonnes up to more than 10 million tonnes.
