            "description": "This visualization depicts changes in Antarctic land ice thickness as measured by the ICESat (2003-2009) and ICESat-2 (2018-) satellites. The camera zooms into a region near the Kamb ice stream to compare ICESat and ICESat-2 beam tracks.  The beam intersections are highlighted to explain how the data at these points are used to measure how land ice has changed over time.  After exploring a few regions in detail, the camera moves out to a global view and an ocean temperature dataset is revealed. || land_ice_antarctica.2870_print.jpg (1024x576) [70.5 KB] || land_ice_antarctica.2870_searchweb.png (320x180) [61.2 KB] || land_ice_antarctica_1080p30.mp4 (1920x1080) [48.6 MB] || land_ice_antarctica_1080p30.webm (1920x1080) [8.8 MB] || land_ice_antarctica (3840x2160) [0 Item(s)] || land_ice_antarctica (5760x3240) [0 Item(s)] || land_ice_antarctica_2160p30.mp4 (3840x2160) [129.9 MB] || land_ice_antarctica_1080p30.mp4.hwshow || ",

            "description": "Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years. 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. || ",

            "description": "This animation shows glacier changes detected by ATM, ICESat and ice bridge data in the highly dynamic Pine Island Glacier. We know that ice speeds in this area have increased dramatically from the late 1990s to the present as the ice shelves in this area have thinned and the bottom of the ice has lost contact with the bed beneath. As the ice has accelerated, ice upstream of the coast must be stretched more vigorously, causing it to thin. NASA-sponsored aircraft missions first measured the ice surface height in this region in 2002, followed by ICESat data between 2002 and 2009. Ice Bridge aircraft have measured further surface heights in 2009 and 2010, and these measurements continue today. Integrating these altimetry sources allows us to estimate surface height changes throughout the drainage regions of the most important glaciers in the region. We see large and accelerating elevation changes extending inland from the coast on Pine Island glacier shown centered here. The changes on Pine Island mark these as potential continuing sources of ice to the sea, and has been surveyed in 2011 by Ice Bridge aircraft and targeted for repeat measurements in coming years. || ",

            "title": "West Antarctica's Weak Spot",
            "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. || ",
