            "description": "The NASA-funded Nationwide Eclipse Ballooning Project allows teams of students from across the U.S. to get a unique view of total solar eclipses with scientific balloons. Before, during, and after a total solar eclipse, teams of college and high-school students use balloons to fly cameras and scientific instruments — either off-the-shelf weather sensors or instruments they built themselves — into the stratosphere to investigate the Sun, the eclipse’s effects on our atmosphere, and other phenomena that are best studied at high altitudes. Started in 2014, the project has not only produced new discoveries but provided hundreds of students with hands-on science and engineering experience along the way.Learn more about the project: https://science.nasa.gov/science-research/heliophysics/nasa-science-soars-during-august-total-solar-eclipse/ || ",

Spanning 11 years, IceBridge produced an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, glaciers and sea ice. Dozens of flights every year provided regular, multi-instrument insights into the behavior of Earth’s rapidly changing cryosphere.\n\nData collected by IceBridge helped scientists bridge the gap in polar observations of ice height between NASA's Ice, Cloud and Land Elevation Satellite (ICESat), which launched in 2003, and ICESat-2, which launched on September 15, 2018. ICESat stopped collecting science data in 2009, making IceBridge critical for ensuring a continuous series of observations. IceBridge surveyed the Arctic and Antarctic areas once a year, typically in the springtime before summer melting began. The first Operation IceBridge flights were conducted in March/May 2009 over Greenland and in October/November 2009 over Antarctica. Other smaller airborne surveys around the world, in particular Alaska, were also part of the IceBridge mission.\n\nLearn More",

The advance and retreat of the front of this ~35-kilometer (~22-mile) wide outlet glacier can be seen in this 6-day interval image series. The rapid flow of inland ice causes the glacier front to advance and two major calving events cause the ice front to retreat.Combined, the 2015 and 2017 calving events have led to the glacier’s ice front being fully disconnected from the North Ice Shelf. The changes to this large outlet from West Antarctica could signal additional sea level contributions from this glacier and the even larger outlet to the west, Thwaites Glacier.Credit: Stef Lhermitte, Delft University of Technology, NetherlandsContains modified Copernicus Sentinel data (2017), processed by ESA || pine_island_1080p.00001_print.jpg (1024x576) [180.8 KB] || pine_island_1080p.00001_searchweb.png (320x180) [98.2 KB] || pine_island_1080p.00001_thm.png (80x40) [6.7 KB] || pine_island_1080p.mp4 (1920x1080) [54.5 MB] || pine_island_720p.mp4 (1280x720) [26.3 MB] || pine_island_1080p.webm (1920x1080) [5.0 MB] || 4104x2304_16x9_30p (4104x2304) [0 Item(s)] || pine_island_2304p.mp4 (4096x2304) [156.5 MB] || ",

Relatively understudied, Nansen’s manageable size lends itself to becoming a proxy for predicting how larger ice shelves will contribute to sea level rise in the decades and centuries to come. By studying the impact of tides, Walker and Dow are able to determine how the rise and fall of floating ice sheets may impact the likelihood of an eventual ice shelf collapse.Complete transcript available.Music: Tiptoe Marimba by Brightside Studio || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_print.jpg (1024x576) [78.0 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_searchweb.png (320x180) [57.6 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_thm.png (80x40) [4.4 KB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.00001_web.png (320x180) [57.6 KB] || APPLE_TV-Nansen_0711217_FINAL_V3_appletv.m4v (1280x720) [129.6 MB] || FACEBOOK_720-Nansen_0711217_FINAL_V3_facebook_720.mp4 (1280x720) [302.8 MB] || LARGE_MP4-Nansen_0711217_FINAL_V3_large.mp4 (1280x720) [244.4 MB] || Nansen_0711217_FINAL_V3.mov (1280x720) [2.6 GB] || TWITTER_720-Nansen_0711217_FINAL_V3_twitter_720.mp4 (1280x720) [53.9 MB] || WEBM-Nansen_0711217_FINAL_V3.webm (960x540) [97.5 MB] || YOUTUBE_1080-Nansen_0711217_FINAL_V3_youtube_1080.mp4 (1920x1080) [403.4 MB] || YOUTUBE_720-Nansen_0711217_FINAL_V3_youtube_720.mp4 (1280x720) [404.4 MB] || APPLE_TV-Nansen_0711217_FINAL_V3_appletv_subtitles.m4v (1280x720) [129.7 MB] || 12666_Nansen_080717.en_US.srt [4.4 KB] || 12666_Nansen_080717.en_US.vtt [4.4 KB] || Nansen_0711217_FINAL_V3_lowres.mp4 (480x272) [32.5 MB] || ",

            "description": "Coccolithophores, a type of phytoplankton, are one-celled, microscopic marine plants that live in large numbers throughout the upper layers of the ocean. They surround themselves with minute calcium carbonate plates called “coccoliths,” which are highly reflective such that populations of these plants can be seen from space. Near the Patagonia Shelf, located east of Argentina and Uruguay, ocean waters thrive with high concentrations of microscopic phytoplankton—e.g., coccolithiphores, dinoflagellates, and diatoms to name a few. That is because in this region the warm, saline, southward-flowing Brazil Current flows past and mixes with the cool, less-saline, nutrient-rich northward-flowing Falklands/Malvinas Current, creating an ideal environment for biological productivity. Scientists use true color satellite images like these, taken by Aqua/MODIS from December 15, 2010 to February 15, 2011, to observe the recurring coccolithophore blooms in the Patagonia Shelf region and study the impacts of ocean acidification on these microscopic organisms. Imagery from these two months shows a coccolithophore bloom (turquoise) near the shelf break. The shelf's unique ecosystem supports important fisheries in the region, providing a favorable reproductive habitat for anchovies and sardines. || ",

            "description": "A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea according to glaciologist and lead author Eric Rignot, of UC Irvine and NASA's Jet Propulsion Laboratory in Pasadena, California.Three major lines of evidence point to the glaciers' eventual demise: the changes in their flow speeds, how much of each glacier floats on seawater, and the slope and depth of the terrain they are flowing over.  In a paper in April, Rignot's research group discussed the steadily increasing flow speeds of these glaciers over the past 40 years. This new study examines the other two lines of evidence.As glaciers flow out from land to the ocean, large expanses of ice behind their leading edges float on the seawater. The point on a glacier where it first loses contact with land is called the grounding line. Nearly all glacier melt occurs on the underside of the glacier beyond the grounding line, on the section floating on seawater.  The Antarctic glaciers studied have thinned so much they are now floating above places where they used to sit solidly on land, which means their grounding lines are retreating inland.—><!——><!—Above: Move bar to compare the grounding line of the Smith Glacier from 1996 (left) to the location in 2011 (right) which has retreated inland 35 km during this time. The green line indicates the location of the 1996 grounding line.  Download HTML to embed this in your web page.The bedrock topography is another key to the fate of the ice in this basin. All the glacier beds slope deeper below sea level as they extend farther inland. As the glaciers retreat, they cannot escape the reach of the ocean, and the warm water will keep melting them even more rapidly.Below are two edited versions of narrated stories released by JPL to explain this research.  In addition are the two versions of the unedited animations provided to JPL to support the release.  The unedited animations show the region of study by the JPL researchers, identifying by name the glaciers that terminate in the Amundsen Sea. One of the animations includes data showing the velocity of the glaciers in the region, flow vectors showing the movement of the glaciers colored by their velocity and a difference image showing the change in velocity between 1996 and 2008.  The second animation does not include these datasets.  Both versions of the animation draw close to the Smith Glacier and show how the grounding line of this glacier has moved inland 35 kilometers between 1996 and 2011.

            "description": "To assess the influence of thermal anomalies on coral communities, the NOAA Coral Reef Watch program in partnership with the University of South Florida, NASA Ames Research Center, UNEP World Conservation Monitoring Center, and the University of Colorado has developed a suite of products that help monitor and forecast global coral bleaching at high spatial resolutions. Thermal anomaly products at 1 km spatial resolution have been developed for the West Florida Shelf using both Advanced Very High Resolution Radiometer (AVHRR) and MODIS Aqua satellite imagery. These products were derived as follows. AVHRR Pathfinder (version 5.0) nighttime-only sea surface temperature (SST) data were used to create a gap-filled climatology from 1985 – 2006 and from it a maximum monthly mean climatology was derived. AVHRR HotSpots are the difference between the AVHRR nighttime-only SST and the AVHRR climatology, while MODIS HotSpots are the difference between the MODIS Aqua 11 µm nighttime-only SST and the AVHRR climatology. Both Degree Heating Weeks (DHWs) products count positive HotSpots equal or higher to 1°C in a 12-week window. When DHW values are between 4 - 8, significant coral bleaching is likely, and the potential for coral disease increases. DHWs values higher than 8 indicates where mass coral bleaching and significant mortality are likely. Maria Vega-Rodriguez of USF || ",

Much of the color likely comes from resuspended sediment dredged up from the sea floor in shallow waters. The sediment-colored water transitions to clearer dark blue near the edge of the continental shelf, where the water becomes deeper. The ocean turbulence that brought the sediment to the surface is readily evident in the textured waves and eddies within the tan and green waters. Tropical Storm Ida had come ashore over Alabama and Florida, immediately east of the area shown here, a few hours before the image was acquired. The storm’s wind and waves may have churned up waters farther west. A second source of sediment is visible along the shore. Many rivers, including the Mississippi River, drain into the Gulf of Mexico in this region. The river plumes are dark brown that fade to tan and green as the sediment dissipates. || ",

These bright swirls of green occur along a continental shelf bustling with biological activity. Phytoplankton blooms often occur along coastlines where nutrient-rich waters well up from ocean depths. The light color of this ocean water suggests the calcite plating of coccolithophores.Farther south along the coast of Namibia, hydrogen sulfide eruptions occur fairly frequently. According to a study published in 2009, ocean currents deliver oxygen-poor water from the north, while the bacteria that break down phytoplankton also consume oxygen, depleting the supply even more. In this oxygen-poor environment, anaerobic bacteria produce hydrogen sulfide gas. When the hydrogen sulfide reaches oxygen-rich surface waters, sulfur precipitates into the water. The sulfur’s yellow mixes with the deep blue ocean to make bright green. So this swirl of bright green could contain phytoplankton, sulfur, or a combination of the two. || ",

Bright greens of plant-life have replaced the deep blues of open ocean water. The Ross Sea is a relatively shallow bay in the Antarctic coastline and due south from New Zealand. As the spring weather thaws the sea ice around Antarctica, areas of open water surrounded by ice—polynyas—open up on the continental shelf. In this open water, sunlight provides the fuel and various current systems provide nutrients from deeper waters to form blooms that can stretch 100 to 200 kilometers (60 to 120 miles).

They had never witnessed such a large area—1250 square miles (~3237 square kilometers)—disintegrate so rapidly. The collapse of the Larsen-B Ice Shelf was captured in this series of images between January 31 and April 13, 2002. At the start of the series, the ice shelf (left) is tattooed with pools of meltwater (blue). By February 17, the leading edge of the C-shaped shelf had retreated about 6 miles (~10 kilometers). By March 7, the shelf had disintegrated into a blue-tinged mixture, or mélange, of slush and icebergs. The collapse appears to have been due to a series of warm summers on the Antarctic Peninsula, which culminated with an exceptionally warm summer in 2002. Warm ocean temperatures in the Weddell Sea that occurred during the same period might have caused thinning and melting on the underside of the ice shelf. || ",

            "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": "Pine Island Glacier was first called the \"weak underbelly\" of the West Antarctic Ice Sheet almost 30 years ago. The nickname stuck in glaciology circles because scientists still fear it is true. Pine Island, or PIG, as it's often called, drains about 10 percent of the entire West Antarctic Ice Sheet. In 2006, the glacier began losing ice mass at an even faster rate than it had before. For scientists concerned with how much PIG could contribute to sea level rise if it lives up to its moniker, there are two key questions. First, why is it changing? Scientists are investigating, among other causes, how the circulation of warming waters under the ice shelf could lead to thinning. Second, how much is it changing? Following the end of the laser altimetry mission ICESat in 2009, NASA launched an airborne campaign called Operation IceBridge to measure critical polar regions. A laser altimeter onboard NASA's DC-8 research airplane has observed PIG continuing the rapid ice loss—measured as a change in elevation—that began to accelerate in 2006. Watch in the visualization below, an analysis partly based on satellite and aircraft data, how NASA has charted PIG's increasing changes. || ",

            "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. || ",

            "description": "The magnitude 9.0 undersea earthquake that occurred off the coast of Japan on March 11, 2011 was one of the five most powerful earthquakes since the modern record began in 1900. A NASA-led team of scientists found another way to observe its might. By closely watching satellite imagery in the aftermath of the tsunami the earthquake created, scientists made the first direct observation of tsunami waves causing icebergs to break off an Antarctic ice shelf. Multiple icebergs broke off of the Sulzberger Ice Shelf, 8,000 miles from the earthquake's epicenter, after the sea swell from the tsunami reached the ice. The first swell took about 18 hours to reach the shelf and was only about a foot high by then. But it caused enough flex in the floating tongue of ice to let loose two large icebergs and several smaller ones that had a combined surface area of two Manhattan islands. Scientists had suspected this could happen, but in this case quickly and correctly predicted where the tsunami swell would hit and then began watching satellite imagery vigilantly. When NASA and European satellite images revealed what they had been looking for, tide data and other models helped confirm that only the tsunami could have been the cause. || ",

            "description": "This animation shows the motion of ice in Antarctica as measured by satellite data from CSA, JAXA and ESA processed by a NASA Research Team at UC Irvine. The background image from Landsat (visible imagery) is progressively replaced by a map of ice velocity color coded on a logarithmic scale, with values varying from 1 m/yr (brown to green) to 3,000 m/yr (green to blue and red). The animation does not show where ice is melting but how ice is naturally transported from the interior regions where it accumulates from snowfall to the coastal regions where it is discharged into the ocean as tabular icebergs and ice-shelf melt water. For the purpose of the animation, we are representing hundreds to thousands of years of motion. In the first animation, the dynamic range of the flow has been compressed, with slower flows scaled up in velocity to make visible how the flows feed from the interior of the continent. In the second, the flows speeds are in scale to each other.The result illustrates that zones of enhanced motion take their source far into the interior regions of Antarctica, at the foothills of the ridges formed by the ice tops of the continent. This pattern of motion has never been observed on that scale before. These observations have vast implications on our understanding of the flow of ice sheets and how they might respond to climate change in the future and contribute to sea level change. || ",

            "description": "Once known for its size, the Jakobshavn Glacier in Greenland is now studied for its speed. In 1997 Jakobshavn ended a decades-long period of stability as it began to thin, accelerate and eject ice into the sea at a rapid rate. The glacier thinned by as much as 50 feet (15 m) per year between 1997 and 2003, according to NASA laser altimetry measurements, while other Greenland glaciers were thinning by about three feet (1 m) per year. The glacier now moves at more than nine miles (15 km) per year, doubling its speed from a decade ago. The glacier's calving front has retreated more than six miles (10 km) in the past decade alone. Scientists point to several warming-related causes for the increase in speed and retreat: meltwater can trickle through cracks in the ice and lubricate the friction point between ice and bedrock, and warmer ocean waters underneath the ice shelf also cause thinning. The thinner ice shelf and meltwater reduce resistance to glacier movement. As a glaciology case study and the greatest potential contributor to sea level rise in the Northern Hemisphere, scientists will continue to watch Jakobshavn closely. || ",

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.

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 mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.Data from campaigns flown prior to the inception of IceBridge will also be archived at NSIDC. These include data from the Airborne Topographic Mapper (ATM) instrument; mountain glacier data from the University of Alaska Fairbanks; and deep radar bedmap data from University of Kansas radar instruments. Combined with NSIDC's existing complete archive of data from the Geoscience Laser Altimeter System (GLAS) instrument aboard ICESat, researchers will be able to access a rich repository of complementary measurements.IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. These flights will provide a yearly, multi-instrument look at the behavior of the rapidly changing features of the Greenland and Antarctic ice.Data collected during IceBridge will help scientists bridge the gap in polar observations between NASA's ICESat — in orbit since 2003 — and ICESat-2, planned for late 2015. ICESat stopped collecting science data in 2009, making IceBridge critical for ensuring a continuous series of observations. || ",

A century later, they're still at it, albeit with a different set of tools. This fall, a team of modern explorers will fly over Earth's southern ice-covered regions to study changes to its sea ice, ice sheets, and glaciers as part of NASA's Operation Ice Bridge.Operation Ice Bridge is a six-year campaign of annual flights to each of Earth's polar regions. The first flights in March and April carried researchers over Greenland and the Arctic Ocean. This fall's Antarctic campaign, led by principal investigator Seelye Martin of the University of Washington, will begin the first sustained airborne research effort of its kind over the continent. Data collected by researchers will help scientists bridge the gap between NASA's Ice, Cloud and Land Elevation Satellite (ICESat) — which is operating the last of its three lasers — and ICESat-II, scheduled to launch in 2014.The Ice Bridge flights will help scientists maintain the record of changes to sea ice and ice sheets that have been collected since 2003 by ICESat. The flights will lack the continent-wide coverage that can be achieved by satellite, so researchers carefully select key target locations. But the flights will also turn up new information not possible from orbit, such as the shape of the terrain below the ice.Six flights are scheduled along Antarctica's peninsula, one along the Getz Ice Shelf, two over the Pine Island Glacier, and two others along the Amundsen coast to include the Thwaites, Smith, and Kohler glaciers. || ",

Many more images of this area will be obtained by the NAC over the coming months as the lunar south pole emerges from the shadows of winter. At meter scales, the geology of this region reminds us that the polar regions of the Moon are still waiting to be explored. The rim of Shackleton crater is a prime candidate for future human exploration due to its proximity to permanently shadowed regions and nearby peaks that are illuminated for much of the year.Last year, Japan's Selene and India's Chandrayaan spacecraft gave us our first high resolution look at the lunar south pole, which includes Shackleton crater. For its size, Shackleton has an exceptionally deep and rugged interior. Usually craters fill in with time as their walls slump and material from afar is thrown in by distant impacts. Much of Shackleton's rim appears rounded and is peppered with smaller craters, indications of a relatively ancient age. Right now it is not clear if Shackleton crater is relatively old or young. This NAC image reveals a shelf on the southeast flank of the crater that is more than two kilometers across and perfectly suitable for a future landing. The extreme Sun angle exaggerates the apparent roughness, however if you look closely at this scale any area that is between small craters could be good candidates for a potential landing site. || ",

            "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. || ",

            "title": "A Tour of the Cryosphere",
            "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. || ",
