[OCEANOGR] A flat sheet of sea ice that is more than 5 miles (8 kilometers) across) Wikipedia, July 23, 2007 (Ice field: An ice field (also spelled icefield) is an area less than 50,000 km(sup2) (19,305 mile)(sup 2) of ice often found in the colder climates and higher altitudes of the world where there is sufficient precipitation. It is an extensive area of interconnected valley glaciers from which the higher peaks rise as nunataks. Ice fields are larger than alpine glaciers, smaller than ice sheets and similar in area to ice caps; under Sea ice: is a floating chunk of sea ice that is less than 10 kilometers (six miles) in its greatest dimension.
