Floe definition, a sheet of floating ice, chiefly on the surface of the sea, smaller than an ice field. a massive portion of a continental ice sheet that projects out over the sea. May be fresh or weathered. conglomerations of small cakes and chunks from other formations, coalesced and refrozen into irregularly shaped elements (2 - 10 cm diam), often w/ sharp projections. simple ice sheet which crystallized slowly . Also, a hillock ofbroken ice that has been forced upward by pressure. Ice shelves are permanent floating sheets of ice that connect to a landmass. However, ice shelves can also form wherever ice flows from land into cold ocean waters, including some glaciers in the Northern Hemisphere. Most of the world's ice shelves hug the coast of Antarctica. GROUNDED iCE Floating ice (e.g., ridge, hummock, orice island) that is aground (stranded) in shoal water. ... terminus of a glacier that ends in a body of water or from the edge of a floating ice shelf that ends in the ocean. a large flattish mass of ice that breaks off from larger ice bodies and floats independently. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic.The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. This produces fast-flowing channels called ice streams. HUMMOCK The raised area ofmultiyear ice formed by the ablation of the surrounding ice. A thick, subcontinental to continental-scale accumulation of glacier ice and perennial snow that spreads from a center of accumulation, typically in all directions. That is because of geothermal heat. See more. According to Rockford fire officials, an individual called 911 to inform dispatchers that the two men were stranded on the sheet of ice, which had begun to … brash ice . Chunks do not really mean something very small like most people may think,it could be a large particle or huge mass. Iceberg. Ice sheets are usually warmer at their base than on the surface. What is a lake? The submerged volume of ice under the hummock is called accumulations of floating ice made up of fragments of not more than 2 meters, the wreckage of other forms of ice. Once on the ice it is time to begin more systematic observations of the ice sheet you want to use to support a load. Antarctic Ice Sheet. An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. It is the second largest ice body in the world, after the Antarctic ice sheet.The ice sheet is almost 2,900 kilometres (1,800 mi) long in a north–south direction, and its greatest width is 1,100 kilometres (680 mi) at a latitude of 77°N, near its northern margin.The mean altitude of the ice is 2,135 metres (7,005 ft). Ice Sheet. A chunk of floating ice that breaks off from a glacier or an ice shelf. There may be many variations in the structure, thickness, temperature, and strength of a floating freshwater ice sheet. When melting occurs, the water lubricates the sheet and it flows more quickly. The Antarctic ice sheet is the largest single mass of ice … Ice floe.
