BergyBit http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.4.3 BergyBit A large piece of floating ice of land origin, showing less than 5 m above sea-level and 100-300 m2 in area (10.4.4 Ed.) [Note: it might be better to say no more than 20 metres long, rather than give an area] BergyBit Bergy bit Glacier http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.2 Glacier A mass of ice predominantly of atmospheric origin, usually moving from higher to lower ground. A seaward margin of a glacier that is aground, the rock basement being at or below sea-level, is termed an ice wall. The projecting seaward extension of a glacier, which is usually afloat, is termed a glacier tongue. In the Antarctic, glacier tongues may extend over many tens of kilometers.

The color is usually white, but sometimes transparent or blue-green or nearly black, normally occupying an area of about 20 m2. Growlers are distinguished with difficulty when they are surrounded by ice and also in heavy swell. Growler Growler IceIsland A large piece of floating ice protruding about 5 m above sea-level, which has broken away from an Arctic ice shelf, having a thickness of 15-30 m and an area of from a few thousand square meters to 500 km2 or more, and usually characterized by a regularly undulating surface which gives it a ribbed appearance from the air. (10.4.3) [Note: Antarctic use is slightly different and refers to a grounded part of a floating ice sheet which rises significantly higher than its surroundings, eg Butler Island. There are also more substantial features, eg the Lyddan Ice Rise.] IceIsland Ice island IceOfLandOrigin http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section1.1.2 IceOfLandOrigin Ice formed on land or in an ice shelf, found floating in water. IceOfLandOrigin Ice of land origin IceShelf http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.3 IceShelf A floating ice sheet of considerable thickness showing 2-50 m or more above sea-level, attached to the coast or a glacier. Usually of great horizontal extent and with a level or gently undulating surface. Nourished by annual snow accumulation at the surface and often also by the seaward extension of land glaciers. Limited areas may be aground. The seaward edge is termed an ice front. IceShelf Ice shelf Iceberg http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.4 Iceberg 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. Iceberg Iceberg IcebergTonque http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.5 IcebergTonque A major accumulation of icebergs, bergy bits and growlers projecting from the coast, held in place by grounding or joined together by fast ice IcebergTonque Iceberg tongue TabularBerg http://www.aari.nw.ru/gdsidb/docs/wmo/nomenclature/WMO_Nomenclature_draft_version1-0.pdf#Section4.4.2 TabularBerg Most flat-topped icebergs form by calving from an ice shelf and show horizontal banding (cf. ice island).
