Absolutely Nothing!. They are all made of ice and are just different lengths and different thicknesses. Hope this answers your questiom
The South Pole sits on Antarctica's ice sheet, which covers 98% of the continent. The Ross Ice Shelf may be the closest to the South Pole, even though it is securely attached to the ice sheet and its connecting boundary is imprecise.
An ice shelf is a floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. The thickness of ice shelves can range from about 100 to 1000 meters (328 to 3280 ft).
The ice sheet holds 100% of Antarctica's . . . ice sheet.
The Ross Ice Shelf is located in Antarctica. It is the largest ice shelf in Antarctica and is about the size of France.
The seaward side of the Filchner-Ronne ice shelf is divided into Eastern (Filchner) 79°00′S 40°00′W and the larger Western (Ronne) 78°30′S 61°00′W sections by Berkner Island. The whole ice shelf covers some 430,000 km², making it the second largest ice shelf in Antarctica, after the Ross Ice Shelf.
an ice sheet is a sheet, ice berg is a berg
An ice shelf forms over water. Antarctica is a continent and is covered -- 98% of the continent -- by an ice sheet. (Ice sheet because it covers more than 50 000 km of land area.)
You can pick any two you want. From the Wikipedia entry: here is a list of the ice shelves, listed clockwise, starting in the West of East Antarctica. An ice sheet is included in the list: "Filchner Ice Shelf "Brunt Ice Shelf "Riiser-Larsen Ice Shelf "Quar Ice Shelf "Ekstrom Ice Shelf "Jelbart Ice Shelf "Fimbul Ice Shelf "Lazarev Ice Shelf "King Baudouin Ice Shelf "Hannan Ice Shelf "Zubchatyy Ice Shelf "Wyers Ice Shelf "Edward VIII Ice Shelf "Amery Ice Shelf "Publications Ice Shelf "West Ice Shelf "Shackleton Ice Shelf "Moscow University Ice Shelf "Voyeykov Ice Shelf "Cook Ice Shelf "Slava Ice Shelf "Gillett Ice Shelf "Nansen Ice Sheet "McMurdo Ice Shelf "Ross Ice Shelf "Swinburne Ice Shelf "Sulzberger Ice Shelf "Nickerson Ice Shelf "Getz Ice Shelf "Dotson Ice Shelf "Crosson Ice Shelf "Cosgrove Ice Shelf "Abbot Ice Shelf "Venable Ice Shelf "Stange Ice Shelf "Bach Ice Shelf "George VI Ice Shelf "Wilkins Ice Shelf "Wordie Ice Shelf "Jones Ice Shelf "Müller Ice Shelf "Prince Gustav Ice Shelf "Larsen Ice Shelf (Larsen A and B) "Ronne Ice Shelf"
size and shape.
The South Pole sits on Antarctica's ice sheet, which covers 98% of the continent. The Ross Ice Shelf may be the closest to the South Pole, even though it is securely attached to the ice sheet and its connecting boundary is imprecise.
The largest remaining ice shelf is the Ross Ice Shelf , which is about the size of France. You can find this ice shelf in east Antarctica.Otherwise, 98% of the continent is covered with an ice sheet.
According to Wikipedia, ice sheets are bigger than ice shelves. Additionally, ice shelves float on water, while ice sheets cover terrain.
Your question is really about ice shelves, not the Antarctic ice sheet. The ice shelves are deteriorating because of warmer ocean waters that melt the ice shelf from below.
An ice shelf is a floating extension of a continental ice sheet, which means generally the only place you find them is in Antarctica. When ice breaks off this ice shelf, which is adjacent to ocean water, it becomes a chunk of (freshwater) ice and floats off to its death. This is an ice berg. Ice bergs refer to any ice in the ocean that has broken off from glaciers, so it doesn't necessarily have to break off an ice shelf. Ice bergs are separate from sea ice, however, which forms from sea water that freezes.
The Milne Ice Shelf was part of the huge Ellesmere Ice shelf which has now broken up into six different ice shelfs. First discovered in 1875-76 by the British Arctic Expedition under the command of Lieutenant Pelham Aldrich.
The ice sheet is not so much a threat to coastlines as are the ice shelves, the Weddell in particular is showing excessive signs of warming and deterioration from exposure to warmer ocean water below the shelf. However, the West Antarctic Ice Sheet may also be in similar peril.
An ice shelf is a floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. The thickness of ice shelves can range from about 100 to 1000 meters (328 to 3280 ft).
