AI overview
An iceberg is a large piece of ice that has broken off from a glacier or ice shelf and floats in the ocean. Icebergs matter because they can pose navigation hazards to ships, reflect changes in climate and glacial systems, and their melting contributes to understanding sea level and ocean conditions.

An iceberg is a piece of fresh water ice more than long that has broken off a glacier or an ice shelf and is floating freely in open water. Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits". Much of an iceberg is below the water's surface, which led to the expression "tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard.
