This is the description Roula chos
There are smaller pieces of ice known as “bergy bits” and “growlers.” Bergy bits and growlers can originate from glaciers or shelf ice, and may also be the result of a large iceberg that has broken up. A bergy bit is a medium to large fragment of ice. Its height is generally greater than three feet but less than 16 feet above sea level and its area is normally about 1,076-3,229 square feet. Growlers are smaller fragments of ice and are roughly the size of a truck or grand piano. They extend less than three feet above the sea surface and occupy an area of about 215 square feet.
