If the West Antarctic Ice Sheet were to completely melt into the ocean, it would raise sea levels worldwide by around 3 meters (10 feet). Although that amount of melt is unlikely in the coming decades, even four inches of sea-level rise can double the frequency of flooding on the U.S. West Coast. The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million square km and contains 30 million cubic km of ice.
A team of scientists and engineers has for the first time successfully drilled over two kilometres through the ice sheet in West Antarctica using . The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martin in Argentina, and originally as the Palmer Peninsula in the US and Graham Land in the United Kingdom, is the northernmost part of the mainland of Antarctica.. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding 1, km ( miles) from a line between Cape Adams (Weddell Sea.
Because it’s a group of islands, much of the West Antarctic Ice Sheet (WAIS, in jargon) is actually sitting on the floor of the Southern Ocean, not on dry land. Parts of it are more than kilometers (1 mile) below sea level. Pine Island is the largest of these islands and the largest ice stream in West Antarctica is called Pine Island Glacier. Scientists have long worried that the West Antarctic ice sheet is a place where climate change might tip toward catastrophe. The ice sheet holds enough water to .

West Antarctica [i.e., the AP toward the West Antarctic Ice Sheet (WAIS)] in austral winter and spring and weak all-season warming over the East Antarctic Ice Sheet (EAIS), which has been suggested by reconstructed datasets (5, 7, 12).
To resolve this limitation, new mechanisms relying on the. The Western Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West (or Lesser) Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains which lies in the Western WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves.
The Antarctic ice sheet is one of the two polar ice caps of the covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth. It covers an area of almost 14 million square kilometres ( million square miles) and contains million cubic kilometres (6, cubic miles) of ice.

Award #: Jennifer Martin, Poet, An Ark of Questions Sent Sailing South: Poetry from Antarctica Award #: Ocean-ice interactions have exerted primary control on the Antarctic Ice Sheet and parts of the Greenland Ice Sheet, and will continue to do so in the near future, especially through melting of ice shelves and calving cliffs.
Retreat in response to increasing marine melting typically exhibits threshold behavior, with little change for forcing below the threshold but a rapid, possibly delayed. The Marie Byrd Land mantle plume formed 50 to million years ago, long before the West Antarctic ice sheet came into existence. At the end of the last ice age aro years ago, the ice sheet went through a period of rapid, sustained ice loss when changes in global weather patterns and rising sea levels pushed warm water closer to the.
The West Antarctic ice sheet was stable in but up to a quarter of its expanse is now thinning. More than metres of ice thickness has been lost in the worst-hit places.
Mass melting of the West Antarctic ice sheet, driven by warmer ocean temperatures, was a major cause of extreme sea level rise more thanyears ago, according to.

A new study connects the dots between climate change and faster melting of the West Antarctic Ice Sheet, which has consequences for sea level rise. By. The Antarctic ice sheet is losing six times as much ice each year as it was in the s and the pace is accelerating, one of the most comprehensive studies of climate change effects on the.
A new paper suggests that the East Antarctic ice sheet may not be as stable as we thought. Looking at ancient melting, the study finds evidence that this piece of the Antarctic experienced meltingyears ago when the world was to degrees Fahrenheit (1 to 2 degrees Celsius) warmer.
Enough ice melted could have occurred here to raise the sea by about 10 to 13 feet. The South Korean research vessel Araon in front of West Antarctica’s Getz Ice Shelf, viewed from a helicopter after researchers deployed on-ice instruments during summer (Photo courtesy of Pierre Dutrieux).The average annual temperature ranges from about minus 10C on the Antarctic coast to minus 60C at the highest points of the interior.
Its immense ice sheet is up to kilometres thick and contains 90 per cent of the world’s fresh water, enough to raise sea level by around 60 metres, were it all to melt. He called it "the weak underbelly of the West Antarctic ice sheet." Here's the cause for concern: When the ice sheet is attached to a bed below sea level, ocean currents can deliver warm water to glacier grounding lines, the location where the ice attaches to the bed.
Scientists recognized that this is the first step in a potential chain reaction.
