The floating terminus of a glacier, typically formed when a terrestrial glacier flow into a deep water basin, such as in Antarctica and the Canadian Arctic. LANDSAT MSS image of a large iceberg separating from the Larsen Ice Shelf. The berg is more than 50 miles long. North-looking photograph showing an iceberg shaped like a dragon, towering ~ 15 feet above the waters of Muir Inlet, Glacier Bay National Park, Alaska.
A sheet of very thick ice with a level or gently undulating surface. It is attached to the land on one side, but most of it is floating. On the seaward side, it is bounded by a steep cliff (ice front) 2 to 50 m or more above sea level. Ice shelves have formed along polar coasts (e.g., Antarctica and Greenland); they are very wide with some extending several hundreds of kilometers toward the sea from the coastline. They increase in size from annual snow accumulation and seaward extension of land glaciers. They decrease in size from warming, melting, and calving.
A broad, flat region of ice along the edge of a continent formed where a continental glacier flowed into the sea.
Floating ice 200 to 1300m thick, that form from the coalescing of glaciers. Ice also forms on the underside of ice shelves to increase their thickness. The Ross Ice Shelf covers an area of 508,000 square kilometres - an area equal to the size of France. The 20,000 year-old expanse of Antarctic ice known as the Larsen Ice Shelf has developed a crack 65 km long. This, combined with the separation of a large iceberg with a surface area of around 2,900 km and a thickness of 200 meters (now making its way north), will require the drafting of new maps of Antarctica. Both changes have been attributed to global warming. (SOURCE: Econet)
where ice is flowing off the main Antarctic plateau and is floating on the sea while still joined to the plateau. Halley Research Station is built on the Brunt Ice Shelf.
A floating ice sheet of considerable thickness attached to a coast. Ice shelves are usually of great horizontal extent and have a level or gently undulating surface. They are nourished by the accumulation of snow and often by the seaward extension of land glaciers. Limited areas may be aground. The seaward edge is termed an ice front.
Large flat layer of ice that extends from the edge of the Antarctic ice cap into the Antarctic Ocean. Source of icebergs.
A continuous plate of floating ice which often extends seaward from a glacier or ice sheet on the shore.
ice that is attached to land but projects out to sea
a floating ice mass that is attached to the coast along at least one
a thick, floating platform of ice that isabelle
a thick slab of ice that is fed by glacier flow, attaches to land along a coastline, and floats on the ocean
a very thick sheet of ice that has been shoved out over the sea floor from a land-based glacier

A floating ice sheet of considerable thickness showing 2-50 meters or more above sea level, attached to the coast.
An ice shelf is a thick slab of floating ice that is next to land.
A floating ice sheet of considerable thickness showing 2-50m or more above sea level, attached to the coast. Usually of great horizontal extent and with a level of gently undulating surface. Nourished by annual snow accumulation and often also by the seaward extension of land glaciers. Limited areas may be aground. The seaward edge is termed an ice front.
a floating ice sheet of considerable thickness attached to a coast (usually of great horizontal extent with a level or gently undulating surface); often a seaward extension of ice sheets
glacial ice that flows out over the sea and remains attached to the glacier
Ice shelf refers to a thick ice sheet of great extent and with a level or undulating surface, fed by snow and sometimes by glaciers, which has reached the sea and is floating, although parts may be aground.
A large flat-topped sheet of ice that is attached to land along one side and floats in the sea or a lake. Formed where a glacier or ice shelf has reached the water and kept flowing, it is fed from the landward side and eroded from the seaward side by the calving of icebergs and melting. Freshwater.
A thick mass of ice extending from a polar shore. The seaward edge is afloat and sometimes extends hundreds of miles out to sea.
portion of an ice sheet that spreads out over water.
An ice shelf is a thick, floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are found in Antarctica, Greenland and Canada only. The boundary between the floating ice shelf and the grounded (resting on bedrock) ice that feeds it is called the grounding line.
