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": "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.
