A mass of ice found floating in the ocean or a lake. Often icebergs form when ice calves from land-based glaciers into the water body. Icebergs can be dangerous to shipping in high and mid-latitude re
gions of the ocean because 90 percent of their mass lies below the ocean surface.
A block of ice that has broken or calved from the face of a glacier and is floating in a body of marine of fresh water. Alaskan icebergs rarely exceed 500 feet in maximum dimension. In order of increa
sing size, the following names are used: Brash Ice, Growler, Bergy Bit.
A massive piece of ice of varying shape, protruding more than 5 m above sea-level, which has broken away from a glacier or an ice shelf, and which may be afloat or aground. Icebergs by their external
look may be subdivided into tabular, dome-shaped, sloping and rounded bergs.
Sea ice terminology. A large, massive piece of floating or stranded glacier ice of any shape detached (calved) from the front of a glacier into a body of water. An iceberg extends more than 5 m above
sea level and has the greater part of its mass (4/5 to 8/9) below sea level.
Large mass of floating or stranded ice, more than 5 metres above the water surface, which has broken away either from a glacier or from an ice-shelf formation.
A large mass of floating or stranded ice that has broken away from a glacier; usually more than 5 m above sea level. The unmodified term "iceberg" usually refers to the irregular masses of ice formed
by the calving of glaciers along an orographically rough coast, whereas tabular icebergs and ice islands are calved from an ice shelf, and floebergs are formed from sea ice. In decreasing size, they are classified as: ice island (few thousand square meters to 500 km^2 in area); tabular iceberg; iceberg; bergy bit (less than 5 m above sea level, between 1 and 200 m^2 in area); and growler (less than 1 m above sea level, about 20 m^2 in area).
A massive piece of ice of greatly varying shape, more than 16 ft (5 m) above sea level, which has broken away from a glacier, and which may be afloat or aground. Icebergs may be described as tabular,
dome-shaped, sloping, pinnacled, weathered, or glacier bergs.
A massive piece of ice of greatly varying shape, more than 5m above sea-level, which has broken away from a glacier (or an ice shelf), and which may be afloat or aground. Icebergs may be described as
tabular, dome-shaped, sloping, pinnacled, weathered or glacier bergs (an irregularly shaped iceberg). Icebergs are not sea ice. They originate from the ice mass of the Antarctic continent that has accumulated over many thousands of years. When they melt they add fresh water to the ocean.
Sea ice terminology describing a major accumulation of icebergs that are projecting toward the coast, held in place by grounding and joined together by fast ice.
