Under the Antarctic Ice - Documentary
Under the Antarctic Ice - Documentary
The Antarctic ice sheet is one of the two polar ice caps of the Earth. It 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 km and contains 26.5 million cubic km of ice. That is, approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to 70 m of water in the world's oceans. In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level. The land in this area would be seabed if the ice sheet were not there. The icing of Antarctica began with ice-rafting from middle Eocene times about 45.5 million years ago and escalated inland widely during the Eocene - Oligocene extinction event about 34 million years ago. CO2 levels were then about 760 ppm and had been decreasing from earlier levels in the thousands of ppm. Carbon dioxide decrease, with a tipping point of 600 ppm, was the primary agent forcing Antarctic glaciation. The glaciation was favored by an interval when the Earth's orbit favored cool summers but Oxygen isotope ratio cycle marker changes were too large to be explained by Antarctic ice-sheet growth alone indicating an ice age of some size. The opening of the Drake Passage may have played a role as well though models of the changes suggest declining CO2 levels to have been more important. Ice enters the sheet through precipitation as snow. This snow is then compacted to form glacier ice which moves under gravity towards the coast. Most of it is carried to the coast by fast moving ice streams. The ice then passes into the ocean, often forming vast floating ice shelves. These shelves then melt or calve off to give icebergs that eventually melt. If the transfer of the ice from the land to the sea is balanced by snow falling back on the land then there will be no net contribution to global sea levels. A 2002 analysis of NASA satellite data from 1979 - 1999 showed that while overall the land ice is decreasing, areas of Antarctica where sea ice was increasing outnumbered areas of decreasing sea ice roughly 2:1. The general trend shows that a warming climate in the southern hemisphere would transport more moisture to Antarctica, causing the interior ice sheets to grow, while calving events along the coast will increase, causing these areas to shrink. A 2006 paper derived from satellite data, measures changes in the gravity of the ice mass, suggests that the total amount of ice in Antarctica has begun decreasing in the past few years. Another recent study compared the ice leaving the ice sheet, by measuring the ice velocity and thickness along the coast, to the amount of snow accumulation over the continent. This found that the East Antarctic Ice Sheet was in balance but the West Antarctic Ice Sheet was losing mass. This was largely due to acceleration of ice streams such as Pine Island Glacier. These results agree closely with the gravity changes. The estimate published in November 2012 and based on the GRACE data as well as on an improved glacial isostatic adjustment model indicates that an average yearly mass loss was 69 ± 18 Gt/y from 2002 to 2010. The West Antarctic Ice Sheet was approximately in balance while the East Antarctic Ice Sheet gained mass. The mass loss was mainly concentrated along the Amundsen Sea coast.- published: 11 Feb 2014

Antarctic ice sheet past 'point of no return'
A study released by NASA and others offers the most definitive evidence that parts of the ice sheet in West Antarctica are melting and the damage is irreversible. The collapse will take more than a century, and the melting will lead to rising sea levels. Judy Woodruff talks to Thomas Wagner of NASA, one of the team's lead members, about the larger consequences of these projections.- published: 13 May 2014

Videofile: West Antarctic Glacier Loss Appears Unstoppable
A new study by researchers at NASA's Jet Propulsion Laboratory and the University of California, Irvine, finds that a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the entire glacial basin from melting into the sea. Three major lines of evidence point to the glaciers' eventual demise: their flow speeds and how they change with time, how much each glacier is floating on seawater rather than lying on land, and the slope of the terrain they are flowing over and its depth below sea level. These glaciers already contribute significantly to sea level rise, releasing as much ice into the ocean each year as the entire Greenland Ice Sheet does.- published: 12 May 2014

WORLD FLOOD: West Antarctic Ice Sheet Melting [Breaking News]
Breaking News: For years, scientists have feared the collapse of the West Antarctic ice sheet—a vast swath of ice that could unleash a slow but unstoppable 10-foot rise in sea levels if it melted. So here is today's terrible news: we now know the ice sheet is melting. And there's pretty much nothing we can do to about it. Ice is melting in the western Antarctic at an unstoppable pace, scientists said Monday, warning that the discovery holds major consequences for global sea level rise in the coming decades. The speedy melting means that prior calculations of sea level rise worldwide made by the Intergovernmental Panel on Climate Change will have to be adjusted upwards, scientists told reporters.

Animals in the Antarctic Ice
Animals in the Antarctic Ice
Animals in the Antarctic Ice The wildlife of Antarctica are extremophiles, having to adapt to the dryness, low temperatures, and high exposure common in Antartica. The extreme weather of the interior contrasts to the relatively mild conditions on the Antarctic Peninsula and the subantarctic islands, which have warmer temperatures and more liquid water. Much of the ocean around the mainland is covered by sea ice. The oceans themselves are a more stable environment for life, both in the water column and on the seabed. The Antarctic ice sheet is one of the two polar ice caps of the Earth. It 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 km and contains 26.5 million cubic km of ice.[2] That is, approximately 61 percent of all fresh water on the Earth is held in the Antarctic ice sheet, an amount equivalent to 70 m of water in the world's oceans. In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level. The land in this area would be seabed if the ice sheet were not there.- published: 16 Nov 2013

When Xavier de Le Rue convinced his main partners The North Face and Swatch to help him set up a dream trip he had in mind, he didn't think it would end up being that good. The expedition with Lucas Debari, on a small boat, to seek the best playground down in Antarctic was a great success. The movie will come out next Fall, here is a Sneak Preview of what happened down there. Captured by TimeLine Films crew and Renan Ozturk from Camp 4 Collective. Next Mission Antarctic episode will be premiered at Verbier during Freeride World Tour final ( march 23rd) and put online right after.

Antarctic glaciers 'melted past point of no return' - This is REAL Genius
A group of scientists from NASA, University of California Irvine and University of Washington have published research suggesting that the West Antarctic ice sheet has melted past the point of no return, and in the next couple of centuries could be directly responsible for sea level rises of several metres worldwide. Their findings were published in the journals Science and Geophysical Research Letters.
