Is it true that most of an iceberg is underwater?

Yes. A USGS water-science page states that most of an iceberg exists below the water surface, and an encyclopedia entry notes only about one-tenth of an iceberg's volume is above water. Several reference books likewise state that most of an iceberg is underwater.
