Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs.
iceberg, floating mass of freshwater ice that has broken from the seaward end of either a glacier or an ice shelf. Icebergs are found in the oceans surrounding Antarctica, in the seas of the Arctic and subarctic, in Arctic fjords, and in lakes fed by glaciers.
Some glaciers and icebergs are blue, for the same reason water is blue. The chemical bond between oxygen and hydrogen in water absorbs light in the red end of the visible light spectrum.
Icebergs are found in the Arctic, North Atlantic, and Southern Oceans. Icebergs float in salt water because they are formed by calving, or splitting, glaciers and are thus made of fresh water. The size of icebergs varies widely.
Harbor seals in icy regions use icebergs shed by glaciers as safe platforms to give birth, care for young and molt. New research finds that as glaciers change with the climate, the resulting changes ...
The Spokesman-Review: Ask Dr. Universe: Icebergs are chunks that have broken off glaciers
Icebergs and glaciers are not just shrinking symbols of a warming planet. As the ice retreats, it is exposing forces that have been locked away for millennia, from buried microbes to unstable ...
