an ice shelf is ice that has been compacted by snow and ice for hundereds of years forming its own land and are disapearing at an alarming rate because of global warming
An ice shelf is glacier ice that has flowed into the sea water over thousands of years and not melted. Ice shelfs float on the sea water, but can be hundreds of feet thick.
No one knows what exists under the Ross Ice Shelf, for example.
The Filchner-Ronne ice shelf is attached to the Antarctic continent.
The Ross ice Shelf is a floating ice shelf connected to the Antarctic continent, that is about the size of France. The ocean under the shelf has never been explored.
Any Antarctic ice shelf calves off sections into the Southern Ocean.
There is an ice shelf named the Ross Ice Shelf, and there is a large sea in the Southern Ocean that surrounds Antarctica called the Ross Sea.
The land to which the Ross Ice Shelf is attached on three sides is the Antarctic continent.
The Antarctic continent is south of the Ronne Ice Shelf. All of the Antarctic continent is surrounded by the Southern Ocean. You can find the Weddell Sea north of the Ronne.
The Ross Ice Shelf is a permanent part of the Antarctic continent, that rises to about 600 feet above sea level. The underside of the shelf remains largely unexplored. Its formation is continuous.
The two largest ice shelves at Antarctica are the Ross Ice Shelf and the Ronnie Ice Shelf. The Antarctic Ice Sheet consists of about 13.72 million sq km of permanent ice representing 90% of the world's ice.
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"
You may be thinking of the Ross Ice Shelf, which is about the size of France, or the Ronnie Larson Ice Shelf, which is decaying from underneath, because of warmer ocean waters around the Antarctic Peninsula.
Berkner Island is a large island in Antarctica. It is surrounded by the Ronne Ice Shelf. The Ronne Ice Shelf is located between the Antarctic Peninsula and Queen Maud Land.
According to the British Antarctic Survey:"The Ross Ice Shelf is the largest ice shelf of Antarctica (an area of roughly 487,000 square kilometres ((188,000 sq mi)) and about 800 kilometres (500 mi) across: about the size of France)."
Ice is found at the polar regions, glaciers and on mountains above the snow line, also on lakes and ponds in winter. Most of the Earth's ice is at the Antarctic. About 90% of the earth's fresh water is locked up in the ice of the Antarctic ice shelf.
The original name for the ice shelf after it was discovered in the late 1940s was changed from the Lassiter Ice ShelfAccording to its Wikipedia entry:"... the Advisory Committee on Antarctic Names (US-ACAN) approved the name Ronne Ice Shelf for this large ice shelf, on the basis of first sighting and exploration of the ice shelf by Ronne and parties under his leadership. The shelf is therefore named for Edith Ronne, the wife of Finn Ronne and RARE Expedition member."This naming process took place after IGY during the late 1950s.Today, properly it is attached to the Filchner ice shelf and is referenced as the Filchner-Ronne Ice Shelf.
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.
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.
The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in Antarctica.The Ross Ice Shelf
The Ross Ice Shelf is bigger
an ice shelf is a shelf of ice, which is floating on the water. There are several large ice shelves around Antarctica.
the Ross ice shelf
A few are named below: Ross ice shelf Ronne/Filchner ice shelf Riiser-Larsen ice shelf Larsen ice shelf
A few of Antarctica's ice shelfs are as named below: Ross ice shelf Ronne/Filchner ice shelf Riiser-Larson ice shelf Larsen ice shelf
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.
The Ronne ice shelf
You may be thinking of ice shelves, one of which, the Ross Ice Shelf, is about the size of France. Ice shelves are attached to the Antarctic continent, but float in the sea and do not count in the total square kilometer measurements of it.
