            "description": "On March 27, 2009, NASA released FROZEN, a twelve-minute show about the Earth's frozen regions designed for Science On a Sphere.  Science On a Sphere was created by NOAA and displays movies on a spherical screen, which is ideal for a show about the Earth or the planets.  The audience can view the show from any side of the sphere and can see any part of the Earth.  Making a movie for this system is challenging, and FROZEN was an exciting project to create.  Until now, only the \"trailer\" for FROZEN has been available for viewing from our site.  Here, for the first time, is an on-line version of the complete show, presented in several different formats that show different aspects of the movie. || ",

            "description": "On the margins of Antarctica, an ice shelve acts as a dam slowing the movement of outlet glaciers flowing toward the sea. However, the ice shelves are exposed to the underlying ocean and may weaken as a result of warm ocean currents. Scientists recently completed an expedition to the ice shelf buffering the Pine Island glacier, a major outlet of the West Antarctic Ice Sheet that has rapidly thinned and accelerated in recent decades. Drilling a shaft through the ice shelf, they submerged instruments beneath the ice to measure ocean velocity, temperature, and salinity. Their observations revealed a 600-m-wide 80-m-deep channel cut into the underside of the ice-shelf that incurs melting beneath the ice shelf of 0.06 m per day. See the paper here for details.This animation shows the ocean currents colored by their velocity circulating around and under the Pine Island ice shelf. Orange and yellow indicate faster currents while green and blue depict slower. A small red marker indicates the location of the drill site. In this animation, the Pine Island ice shelf is temporarily sliced away to reveal the ocean flows under the ice and subsequently restored up to the location of the drill site. A shaft penetrates through the ice sheet and the instrument is lowered through the shaft into the water that flows beneath the ice shelf. In this animation, the topography and ice shelf thickness is exaggerated by 15 times. || ",

            "description": "Water doesn't flow here; it freezes. Snow falls often, and if it melts it is likely to freeze again and add to the accumulation of ice that can date back thousands of millennia. If you can see the ground, it is frozen. If you cannot see the ground, it could be sitting under ice miles thick, like in Antarctica. This is the cryosphere, those regions of Earth from the North and South poles to mountain ranges near the Equator where water is found in solid form. The cryosphere covers many landscapes, but remains dominated by the polar regions. A cover of floating sea ice cracks, shrinks and expands constantly over the Arctic. Sheets of ice cover the bases of mountain ranges and cling to craggy bedrock in Antarctica and Greenland—the two ice sheets alone account for 90 percent of the fresh water on the planet. These regions of the cryosphere are important to scientists because they regulate global climate and are seeing more dramatic climate-driven changes than other regions. The Arctic is warming faster than any spot on Earth while receding and accelerating glaciers in Antarctica and Greenland raise the concern of sea level rise. Watch in the narrated tour below how NASA uses its satellite fleet to observe the remote reaches of the cryosphere. || ",

This is Antarctica, where ice sheets stretch across the eastern part of the continent like a frozen Great Plains, and mountains that would be at home in the Rockies crop up in nearly snow-free, dry regions. Otherwise experienced by only a small group of scientists and polar travelers, NASA, in partnership with the National Science Foundation, the U.S. Geological Survey, and the British Antarctic Survey, has made Antarctica accessible to all by piecing together Landsat 7 satellite images to create a mosaic that represents the first true-color, high-resolution map of the continent.

            "description": "Stretching off the edge of the continent, 1,400 miles west of Antarctica's McMurdo Station, is Pine Island Glacier (PIG)—a massive river of ice 190 miles wide and 30 miles long that satellite measurements reveal is rapidly shrinking in size. Much of the glacier rests on a bed below sea level and global sea levels could increase by three feet or more if the glacier melted completely. The rate of ice loss on the glacier has increased rapidly in recent years, and scientists believe shifting warm water rising from the adjacent deep ocean and circulating in the surrounding Amundsen Sea are rapidly melting the underside of the glacier's floating edge—the ice shelf. To be certain requires measurements taken beneath this floating ice. That's where NASA polar scientist Robert Bindschadler comes in. In 2008, Bindschadler led an expedition to the remote ice shelf by plane, but the dangers of landing on the crevassed surface prevented his team from collecting data. This fall Bindschadler will return via helicopter. The plan on arrival: drill 1,640 feet below the surface and deploy a specially designed instrument that will start continuous measurements of the shifting ocean waters beneath the glacier. || ",

The field expedition for this international partnership involves scientific investigations along two overland traverses in East Antarctica: one going from the Norwegian Troll Station to the United States South Pole Station in 2007-2008; and a return traverse by a different route in 2008-2009. This project will investigate climate change in East Antarctica.One of the most pressing environmental issues of our time is the need to understand the mechanisms of current global climate change and the associated impacts on global economic and political systems. In order to predict the future with confidence, we need a clear understanding of past and present changes in the Polar Regions and the role these changes play in the global climate system.For more information about this project go to http://traverse.npolar.no || ",

            "description": "Jakobshavn Isbrae is located on the west coast of Greenland at Latitude 69 N. The ice front, where the glacier calves into the sea, receded more than 40 km between 1850 and 2006. Between 1850 and 1964 the ice front retreated at a steady rate of about 0.3 km/yr, after which it occupied approximately the same location until 2001, when the ice front began to recede again, but far more rapidly at about 3 km/yr. As more ice moves from glaciers on land into the ocean, it causes a rise in sea level. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of the ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This may be due in part to the numerous melt lakes visible here near the top of the image. These are believed to lubricate the layer between the ice sheet and bedrock, causing the ice to flow faster toward the sea. See an animation illustrating this acceleration in item #10153. || ",

            "description": "The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each year. Since ice and snow exist relatively close to their melting point, they frequently change from solid to liquid and back again due to fluctuations in surface temperature. Although direct measurements of the cryosphere can be difficult to obtain due to the remote locations of many of these areas, using satellite observations scientists monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.This animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The animation begins in Antarctica, showing some unique features of the Antarctic landscape found nowhere else on earth. Ice shelves, ice streams, glaciers, and the formation of massive icebergs can be seen clearly in the flyover of the Landsat Image Mosaic of Antarctica. A time series shows the movement of iceberg B15A, an iceberg 295 kilometers in length which broke off of the Ross Ice Shelf in 2000. Moving farther along the coastline, a time series of the Larsen ice shelf shows the collapse of over 3,200 square kilometers ice since January 2002. As we depart from the Antarctic, we see the seasonal change of sea ice and how it nearly doubles the apparent area of the continent during the winter.From Antarctica, the animation travels over South America showing glacier locations on this mostly tropical continent. We then move further north to observe daily changes in snow cover over the North American continent. The clouds show winter storms moving across the United States and Canada, leaving trails of snow cover behind. In a close-up view of the western US, we compare the difference in land cover between two years: 2003 when the region received a normal amount of snow and 2002 when little snow was accumulated. The difference in the surrounding vegetation due to the lack of spring melt water from the mountain snow pack is evident.As the animation moves from the western US to the Arctic region, the areas affected by permafrost are visible. As time marches forward from March to September, the daily snow and sea ice recede and reveal the vast areas of permafrost surrounding the Arctic Ocean.The animation shows a one-year cycle of Arctic sea ice followed by the mean September minimum sea ice for each year from 1979 through 2008. The superimposed graph of the area of Arctic sea ice at this minimum clearly shows the dramatic decrease in Artic sea ice over the last few years.While moving from the Arctic to Greenland, the animation shows the constant motion of the Arctic polar ice using daily measures of sea ice activity. Sea ice flows from the Arctic into Baffin Bay as the seasonal ice expands southward. As we draw close to the Greenland coast, the animation shows the recent changes in the Jakobshavn glacier. Although Jakobshavn receded only slightly from 1964 to 2001, the animation shows significant recession from 2001 through 2009. As the animation pulls out from Jakobshavn, the effect of the increased flow rate of Greenland costal glaciers is shown by the thinning ice shelf regions near the Greenland coast.This animation shows a wealth of data collected from satellite observations of the cryosphere and the impact that recent cryospheric changes are making on our planet.For more information on the data sets used in this visualization, visit NASA's EOS DAAC website.Note: This animation is an update of the animation 'A Short Tour of the Cryosphere', which is itself an abridged version of the animation 'A Tour of the Cryosphere'. The popularity of the earlier animations and their continuing relevance prompted us to update the datasets in parts of the animation and to remake it in high definition. In certain cases, our experiences in using the earlier work have led us to tweak the presentation of some of the material to make it clearer. Our thanks to Dr. Robert Bindschadler for suggesting and supporting this remake. || ",

Viewers see the Earth suspended in darkness as if it were floating in space. Moving across the planet's face, viewers see the undulating wisps of clouds, the ephemeral sweep of fallen snow, the churning crash of shifting ice, and more.FROZEN brings the Earth alive. Turning in space, the sphere becomes a portal onto a virtual planet, complete with churning, swirling depictions of huge natural forces moving below. FROZEN features the global cryosphere, those places on Earth where the temperature doesn't generally rise above water's freezing point. As one of the most directly observable climate gauges, the changing cryosphere serves as a proxy for larger themes.But just as thrilling as this unusual—and unusually realistic—look at the planet's structure and behavior is the sheer fun and fascination of looking at a spherically shaped movie. FROZEN bends the rules of cinema, revealing new ways to tell exciting, valuable stories of all kinds. The movie may be FROZEN, but the experience itself rockets along. || ",

It is an area of Antarctica which is experiencing rapid changes. The grounding line of Pine Island Glacier is retreating, the glacier is thinning rapidly, and its ice flow is accelerating. Additionally, the sea ice cover in front of the glacier has been decreasing steadily for several decades.

            "description": "Antarctica is the highest, driest, coldest, windiest and brightest of the seven continents. It is roughly the size of the United States and Mexico combined and is almost completely covered by a layer of ice that averages more than one mile in thickness, but is nearly three miles thick in places. This ice accumulated over millions of years through snowfall. Presently, the Antarctic ice sheet contains 90% of the ice on Earth and would raise sea levels worldwide by over 200 feet were it to melt. The total surface area is about 14.2 million sq km (about 5.5 million sq mls) in summer, much larger then the continental United States, approximately twice the size of Australia, and fifty times the size of the UK. In this still image, Antarctica is shown using the Landsat Image Mosaic of Antarctica (LIMA) data with the continental United States overlaid on top for size comparison.

            "description": "Antarctica is a land mass surrounded by an ocean which allows the sea ice here to move more freely than it does in the Northern Hemisphere. Because there are no surrounding continents to limit its movement, the sea ice is free to float northward into warmer waters where it eventually melts. As a result, almost all of the sea ice that forms during the Antarctic winter melts during the summer. During the winter, up to 18 million square kilometers (6.9 million square miles) of ocean is covered by sea ice, but by the end of summer, only about 3 million square kilometers (1.1 million square miles) of sea ice remain. Both Arctic and Antarctic sea ice extent are characterized by fairly large variations from year to year. The monthly average extent can vary by as much as 1 million square kilometers (386,102 square miles) from the year-to-year monthly average. The area covered by Antarctic sea ice has shown a small increasing trend.The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor which is not so sensitive to atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfall. The false color in this animation of sea ice surrounding the South Pole is derived from the daily AMSR-E 6.25 km 89 GHz brightness temperature while the sea ice extent is derived from the daily AMSR-E 12.5 km sea ice concentration. The sea ice extent shown is generated using a three day moving average where the daily sea ice concentration is at least 15%. This animation progresses at a rate of four frames per day from June 4, 2005 through November 18, 2005. || ",

            "description": "Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier gradually receded until about 1950, where it remained stable for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase.
