Over land, continuous permafrost is shown in a dark pink while discontinuous permafrost is shown in a lighter shade of pink. Over much of the northern hemisphere's land area, a semi-transparent white veil depicts the regions that are affected by snowfall at least one day during the perion 2000-2012. The bright green line along the southern border of this region shows the maximum snow extent while a black line across the North America, Europe and Asia shows the 50% snow extent line. Glaciers are shown as small golden dots in mountainous areas and in the far northern and southern latitudes. Over the water, ice shelves are shown around Antarctica along with sea ice surrounding the ice shelves. Sea ice is also shown at the North Pole, where the 30 year average sea ice extent is shown by a yellow outline. In addition, the ice sheets of Greenland and Antarctica are clearly visible. || ",

In 2001, the British Antarctic Survey (BAS) released a map of the bed under the Antarctic Ice Sheet and the seabed extending out on to the continental shelf derived from data collected by an international consortium of scientists over the prior fifty years. The resulting dataset was called BEDMAP (or BEDMAP1).In 2013, BAS released an update of the topographic dataset called BEDMAP2 that incorporates twenty-five million measurements taken over the past two decades from the ground, air and space. This visualization compares the new BEDMAP2 dataset to the original BEDMAP1 dataset showing the improvements in resolution and coverage. <!——><!—Above: Move bar to compare the Bedmap1 topography (left) to the Bedmap2 topography (right).

This visualization highlights the contribution that OIB has made to this important dataset.The topography in this visualization is exaggerated to emphasize the topographic relief. The amount of exaggeration varies based on the viewpoint, from twenty times in distant views down to nine times when near the Pine Island Bay. || ",

Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season.

This animation first shows the advance and retreat of the Arctic sea ice followed by same for the Antarctic sea ice. The sea ice changes from day to day showing a running 3-day average sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running miniimum of the AMSR-E 89 GHz brightness temperature. The animation ends by flying over the Antarctic Peninsula.This was created for a planetarium dome show called Dynamic Earth and is produced in 'domemaster format'. The domemaster format was created by rendering 7 separate 2048x2048 camera tiles. The tiles were then stitched together to form final domemaster at 4096x4096 resolution. Both the tiles and the domemaster were rendered with 16 bits per channel with no gamma correction. Two domemaster layers were generated for this animation: the Earth showing sea ice advancing or retreating rendered with transparency and the star background without transparency.This visualization was shown in the \"VR Village\" at SIGGRAPH 2015. || ",

            "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. 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 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 portrays the changes in the sea ice from May 26, 2009 through July 29, 2010. || ",

            "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.

            "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. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006.This animation is an update of, and extension to, animation IDs #3374 and #3434.In this version, the pause on the approach to the Jakobshavn glacier where the meltwater lakes on the Greenland ice sheet are visible is shortened. In addition, the colors showing regions of elevation increase and decrease over the Greenland ice sheet are modified. || ",

            "description": "Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover.  The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade.  But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. 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.  This animation progresses at a rate of six frames per day from January 1, 2007 through the minimum extent which occurred on September 14, 2007. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures or divergence areas in the sea ice cover by warm brightness temperatures (in blue) while cold brightness temperatures, shown in brighter white, represent consolidated sea ice. The sea ice edge is defined by the 15% ice concentration contour in the three-day moving average of the AMSR-E 12.5 km sea ice concentration data while ice extent is the sum of all pixels with at least 15% ice.An image of the sea ice on September 14, 2007 is included below, along with a corresponding image from September 21, 2005 showing the previous minimum sea ice extent. || ",

            "title": "Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006",
            "description": "Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point 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. This animation shows the glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006.This animation is an update of and extension to animation ID #3374. In this version, a pause is added on the approach to the Jakobshavn glacier in order to highlight the meltwater lakes visible on the Greenland ice sheet. In addition, semi-transparent overlays and text indicate different regions of the glacier before the calving lines are shown. After the calving front retreat, an additional segment shows a zoom to a global view. During the pull out, historic calving front locations are shown followed by a color overlay showing regions of increase and decrease in the Greenland ice sheet. || ",

The two-hour television special, broadcast on the Discovery Channel in the spring of 2007, explores how the world changes over different timescales ... from billionths of seconds to billions of years. This animation portrays a variety of remotely sensed data elements at different temporal resolutions.Initially, the animation shows cloud cover in motion over North America in half-hour increments from Nov. 26 to Dec. 7, 2005. The temporal pace quickens to show a 5-day moving average of daily MODIS snow cover along with daily AMSR-E sea ice from Dec. 7, 2005 to Mar. 15, 2006. As the view swings south over the Gulf of Mexico, the AMSR-E Sea Surface Temperature reveals warming ocean temperatures from March through August, 2006. As it passes over the Atlantic Ocean, the biosphere fades into view, showing both chlorophyll concentration in the ocean along with Normalized Difference Vegetation Index over the land areas. The biosphere animates over time while the view pans over northern Africa and Europe, showing data collected from September 2002 through February 2006.This program was also broadcast in Japan through a partnership with the NHK international broadcasting service and in France through a partnership with the ARTE television network. || ",

            "description": "A new HD version of this animation is available here.Click here to go to the media download section.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 ice thickness ranging from 2.7 to 4.8 kilometers thick along with swaths of polar stratospheric clouds. In a tour of this frozen continent, the animation shows 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. 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 size of the continent during the winter.From Antarctica, the animation travels over South America showing areas of permafrost over 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 effected by permafrost are visible. In December, we see how the incoming solar radiation primarily heats the Southern Hemisphere. As time marches forward from December to June, the daily snow and sea ice recede as the incoming solar radiation moves northward to warm the Northern Hemisphere.Using satellite swaths that wrap the globe, the animation shows three types of instantaneous measurements of solar radiation observed on June 20, 2003: shortwave (reflected) radiation, longwave (thermal) radiation and net flux (showing areas of heating and cooling). Correlation between reflected radiation and clouds are evident. When the animation fades to show the monthly global average net flux, we see that the polar regions serve to cool the global climate by radiating solar energy back into space throughout the year.The animation shows a one-year cycle of the monthly average Arctic sea ice concentration followed by the mean September minimum sea ice for each year from 1979 through 2004. A red outline indicates the mean sea ice extent for September over 22 years, from 1979 to 2002. The minimum Arctic sea ice animation clearly shows how over the last 5 years the quantity of polar ice has decreased by 10 - 14% from the 22 year average.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 1042 to 2001, the animation shows significant recession over the past three years, from 2002 through 2004.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. || ",
