An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in the open sea. Because the sea around this iceberg is so calm, the underwater portion is visible through the clear water. The largest iceberg ever detected was B-15, which split from the Ross Ice Shelf in Antarctica in 2000, and had a flat top; it had a surface area of 11,000 km2 (4,200 sq mi) and broke into several pieces in 2002 and 2003. This picture depicts an irregularly shaped iceberg with a rounded top, calved from a glacier in the Arctic and photographed in the Arctic Ocean north of Svalbard.Photograph credit: Andreas Weith
