With high-resolution data from ICESat-2’s laser altimeter, scientists will track changes to Earth’s polar ice caps – regions that are a harbinger of warming temperatures worldwide. The mission will also take stock of forests, map ocean surfaces, track the rise of cities and measure everything in between. ICESat-2 continues key elevation observations begun by ICESat-1 (2003 to 2009) and Operation IceBridge (2009 through present), to provide a portrait of change in the beginning of the 21st century.\n\nFor more information, please visit the  ICESat-2 website.",

The camera starts out at a global view of Antarctica before zooming into the Ross Archipelago region. RADARSAT DEM data is shown as the camera pushes in, showing the limits of the data resolution.  A wipe transition reveals the REMA data, exposing additional details as the camera moves down towards the surface.  Terrain is represented as a mesh to show the full resolution of the data. The camera flies up a valley, exploring the detailed REMA data.  LIMA imagery is revealed at the end of the visualization.

Rink Glacier in central west Greenland is one example of a 25-year-long time series of elevation changes.  In these visualizations, elevation data for each aircraft flight over the glacier are illustrated using spheres 1m in diameter, with each sphere representing a specific measurement.  When viewed together, the spheres form sheets defining the observed surface of the glacier for a given year.  The spheres are colored by year, and over time we can see how the glacier's elevation changes. Towards the end of the visualization, the study area of the Rink Glacier is compared to the future coverage of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), as represented by bright green crisscrossing ground tracks. || ",

                        "description": "The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. In these regions, the surface water becomes dense enough to sink to the ocean depths. This pumping of surface water into the deep ocean forces the deep water to move horizontally until it can find an area on the world where it can rise back to the surface and close the current loop. This usually occurs in the equatorial ocean, mostly in the Pacific and Indian Oceans. This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea. The surface ocean current brings new water to this region from the South Atlantic via the Gulf Stream and the water returns to the South Atlantic via the North Atlantic Deep Water current. The continual influx of warm water into the North Atlantic polar ocean keeps the regions around Iceland and southern Greenland mostly free of sea ice year round.The animation also shows another feature of the global ocean circulation: the Antarctic Circumpolar Current. The region around latitude 60 south is the the only part of the Earth where the ocean can flow all the way around the world with no land in the way. As a result, both the surface and deep waters flow from west to east around Antarctica. This circumpolar motion links the world's oceans and allows the deep water circulation from the Atlantic to rise in the Indian and Pacific Oceans and the surface circulation to close with the northward flow in the Atlantic.The color on the world's ocean's at the beginning of this animation represents surface water density, with dark regions being most dense and light regions being least dense (see the animation Sea Surface Temperature, Salinity and Density). The depths of the oceans are highly exaggerated to better illustrate the differences between the surface flows and deep water flows. The actual flows in this model are based on current theories of the thermohaline circulation rather than actual data. The thermohaline circulation is a very slow moving current that can be difficult to distinguish from general ocean circulation. Therefore, it is difficult to measure or simulate. || ",

                        "description": "Music: \"Overview Effect,\" \"All In Stride,\" Universal Production Music. NASA utilizes advanced satellite lidar technology to better understand and observe Earth’s forests—crucial ecosystems that absorb roughly 30 percent of atmospheric carbon. Remote sensing scientist, Laura Duncanson, explains the challenge of studying vast, remote regions where traditional field research is limited. For over 50 years, satellites like Landsat have tracked forest cover, but have lacked the ability to measure how much carbon these forests contain. That’s where NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission comes in. GEDI provides high-resolution 3D data on tree canopy height, canopy structure, and surface elevation, allowing scientists to determine forest biomass. However, based on GEDI’s orbit on the International Space Station (ISS), it is unable to capture data near Earth’s poles. To fill that gap, NASA uses the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2), which, although not originally designed for forests, provides complementary 3D forest data, especially in boreal regions. Together, the two lidar systems enable the first comprehensive global biomass map, revealing where and how much carbon is being lost or regained in forests. With this new understanding comes smarter conservation and restoration efforts, assisting in identifying carbon-rich areas to prioritize protection. With these NASA Earth science missions, we can see a clearer global picture of our planet and its carbon balance.

The results provide insights into how the polar ice sheets are changing, demonstrating definitively that small gains of ice in East Antarctica are dwarfed by massive losses in West Antarctica. The scientists found the net loss of ice from Antarctica, along with Greenland’s shrinking ice sheet, has been responsible for 0.55 inches (14 millimeters) of sea level rise between 2003 and 2019 – slightly less than a third of the total amount of sea level rise observed in the world’s oceans. || ",

The animation was created and produced by media art students from the Savannah College of Art in Design (SCAD) in Georgia, in collaboration with NASA’s Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) mission. Their goal was to communicate the science and engineering of the mission, slated for launch in 2018. ICESat-2, managed by NASA Goddard in Greenbelt, Maryland, will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. ICESat-2 will carry a photon-counting laser altimeter that will allow scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail. The workings of this laser helped inspire students to create the character of Pho and plot his adventure. Our planet's frozen and icy areas, called the cryosphere, are a key focus of NASA's Earth science research. ICESat-2 will help scientists investigate why, and how much, our cryosphere is changing in a warming climate. The satellite will also measure heights across Earth's temperate and tropical regions, and take stock of the vegetation in forests worldwide.

                        "description": "Next month, NASA will launch into space the most advanced laser instrument of its kind, beginning a mission to measure – in unprecedented detail – changes in the heights of Earth’s polar ice.NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second.“ICESat-2’s new observational technologies will advance our knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise while also helping us understand the connection of sea ice loss to the global system,” said Thomas Wagner, cryosphere program scientist in NASA’s Science Mission Directorate.ICESat-2 will extend and improve upon NASA's 15-year record of monitoring the change in polar ice heights, which started in 2003 with the first ICESat mission and continued in 2009 with NASA’s Operation IceBridge, an airborne research campaign that monitors the accelerating rate of change.ICESat-2 represents a major technological leap in our ability to measure changes in ice height. Its Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from the spacecraft to Earth and back.NASA will host a media teleconference at 1 p.m. EDT Wednesday, Aug. 22, to discuss the upcoming launch of the Ice, Cloud and land Elevation Satellite (ICESat-2), which will fly NASA's most advanced laser altimeter to measure Earth’s changing ice. The teleconference will stream live on NASA's website.ICESat-2 is scheduled to launch Sept. 15 from Vandenberg Air Force Base.The briefing participants are:    • Tom Wagner, cryosphere program scientist in the Science Mission Directorate (SMD) at NASA Headquarters    • Richard Slonaker, ICESat-2 program executive in SMD    • Doug McLennan, ICESat-2 project manager at NASA’s Goddard Space Flight Center    • Donya Douglas-Bradshaw, Advanced Topographic Laser Altimeter System (ATLAS) instrument project manager at Goddard    • Tom Neumann, ICESat-2 deputy project scientist at GoddardFor more information:Media AdvisoryICESat-2 Video Resources || ",
