Some named Antarctic iceshelves. Ice shelf extending approximately 6 miles into the Antarctic Sound from Joinville Island. An ice shelf is "a floating slab of ice originating from land of considerable thickness extending from the coast (usually of great horizontal extent with a very gently sloping surface), resulting from the flow of ice sheets, initially formed by the accumulation of snow ...
A third division is by latitude: from polar seas with ice shelves, sea ice and icebergs, to temperate and tropical waters. [3]: 150–151 Coral reefs, the so-called "rainforests of the sea", occupy less than 0.1 percent of the world's ocean surface, yet their ecosystems include 25 percent of all marine species. [86]
Ice sheet: A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill

Ice sheets are bigger than ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km 2 are termed an ice cap. An ice cap will typically feed a series of glaciers around its periphery. Although the surface is cold, the base of an ice sheet is generally warmer due to geothermal heat. In places, melting occurs and the melt-water ...
Of the continent's 162 ice shelves, 68 show significant shrinking between 1997 and 2021, while 29 grew, 62 didn’t change and three lost mass but not in a way scientists can say shows a ...
The Ross Ice Shelf is the main outlet for several major glaciers draining the West Antarctic Ice Sheet, which contains the equivalent of 5 m of sea level rise in its above-sea-level ice." The report added that observations of "iceberg calving" on the Ross Ice Shelf are, in their opinion, unrelated to its stability. [10]
The Antarctic continental shelf is involved in global climate regulation and temperature stability through the overturning of water masses, where heat is circulated throughout the ocean. When ice forms, it results in brine rejection, where salt is expelled and dense water forms along the continental shelf.
