WebJan 6, 2024 · This means that ice has nine-tenths, or 90 percent of water’s density – and so 90 percent of the iceberg is below the water’s surface. What percentage of the iceberg was under water? Over 87% of an iceberg’s volume (and mass) is underwater. Typically about one-tenth of the volume of an iceberg is above water, which follows from Archimedes's Principle of buoyancy; the density of pure ice is about 920 kg/m (57 lb/cu ft), and that of seawater about 1,025 kg/m (64 lb/cu ft). The contour of the underwater portion can be difficult to judge by looking at the portion above the surface. The largest icebergs recorded have been calved, or broken off, from the Ross Ice Shelf of Antarctica. … chirton newcastle
