It is moving with the shelf ice at about 200 meters per year towards the open sea.

Winter: Winter months bring the risk of shelf ice.

Because of the uneven surface and possible air holes throughout shelf ice, the ice may give way unexpectedly.

Melting or breakup of floating shelf ice does not affect global sea levels, and happens regularly as shelves grow.

Shelf ice can refer to the ice that forms when a portion of a lake surface freezes.

In Antarctica many such lakes occur inland, some on shelf ice close to sea level, others high among mountains or nunataks.

Created by the wind and waves, the shelf ice is a jumble of ice chunks, pushed onto each other.

The Markham split is the latest loss, leaving Ellesmere with only around 800 square kilometers of shelf ice.

During these surf seasons there is often snow, shelf ice, and some ice in the water, making access difficult and conditions more dangerous.

Shelf ice forms from float ice.

The individual pieces (ice in the case of shelf ice) are not initially connected; they only float upon the water surface and rest upon each other.

Including the Markham loss, Ellesmere Island has now lost 10 times more shelf ice this summer than scientists predicted on July 30.

After their loss the reduced buttressing of feeder glaciers has allowed the expected speed-up of inland ice masses after shelf ice break-up.

On March 10, 1959, the Soviet Union set up the research station Lazarev on the shelf ice in the region of the Schirmacher Oasis.

He named it the "Lassiter Shelf Ice" and gave the name "Edith Ronne Land" to the land presumed to lie south of it.

Shelf ice is a floating mat of ice, but unlike a pond or a small lake that freezes over, the shelf is not a uniform sheet of ice.

The annual World Ice Golf Championship has been held on the world's northernmost golf course on the shelf ice near Uummannaq, Greenland since 1997.

Breeding groups of over 2000 have recently been found among the shelf ice of the Weddell Sea (Hempel and Stonehouse, 1987); a small breeding population occurs on South Georgia.

After threading her way through the pack ice over the ensuing weeks, Yancey finally arrived at Bay of Whales, Antarctica, mooring at the shelf ice on 18 January 1947.

In 1983, the Dakshin Gangotri Station was set up on the shelf ice, about 90 km from the Schirmacher Oasis, but was decommissioned in 1989 due to excessive snow accumulation.

Although this is small compared to the 3250 square kilometers that broke off of the Larsen B ice shelf in 2002, it leaves only a thin strip of shelf ice protecting the larger Wilkins ice shelf.

Wireless reports have spoken of the breathtaking, four-hour, nonstop flight of our squadron on November 21st over the lofty shelf ice, with vast peaks rising on the west, and the unfathomed silences echoing to the sound of our engines.

It was used on a small scale in 2007 to supplement microwave radiometer measurements during the Pol-Ice campaign and on a much larger scale during the GreenICE (Greenland Arctic Shelf Ice and Climate Experiment) campaign conducted in 2004 and 2005.

Such rapid and unexpected changes in climate-forcing events eventually suggest that modelers need to include parameters such as ocean temperature thermoclines, energy accumulation in the tropical oceans, sea ice extents in the polar regions, land glacial ice retraction in Greenland, and sheet ice and shelf ice remodeling in Antarctica.
