A piece of ice smaller than a bergy bit that floats with less than 1 meter (3.3 feet) showing above water, often almost awash. A growler generally appears white but sometimes transparent or blue- green or nearly black in colour. Normally occupying an area of about 20 square meters, growlers are difficult to distinguish when surrounded by sea ice or in high seas. Growlers are usually a fragment of an iceberg or floeberg and its surface often is heavily pitted.
