ICESat First Light Release: Antarctica, from Coast to Coast |
| Abstract |
ICESat's first topographic profiles across the continent reveal the textured surfaces of Antarctic ice sheets in unprecedented detail. The following profile spans the entire Antarctic continent from coast to coast. The transect begins near Wrigley Gulf, crosses the Ross Ice Shelf and central Antarctica, finally tapering off at the Amery Ice Shelf. The high flat area in the center of the continent is called the East Antarctic plateau. |

Nadir View of Change in Elevation over Greenland with a Blue/Yellow Color Scale |
| Abstract |
Changes in the Greenland and Antarctic ice sheets are critical in quantifying forecasts for sea level rise. Since its launch in January 2003, the ICESat elevation satellite has been measuring the change in thickness of these ice sheets. This image of Greenland shows the changes in elevation over the Greenland ice sheet between 2003 and 2006. Gray areas indicate no change in elevation. The white regions indicate a slight thickening, while the blue and purple shades indicate a thinning of the ice sheet. |

| Title |
Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006 |
| Abstract |
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. |

ICESat First Light Release: Antarctica in Three Dimensions |
| Abstract |
ICESat's orbit was designed to maximize coverage over the great polar ice sheets, where ground tracks overlap to create an intricate grid of data points. The accumulation of these data points in the Southern Hemisphere results in a new three-dimensional elevation model of Antarctica. ICESat repeats its orbital pattern every eight days, allowing the GLAS instrument to measure changes over time in the same location. In order to measure ice sheet mass balance, the satellite's advanced technology is providing data on the critically important third dimension, elevation. |

| Abstract |
ICESat satellite laser altimeter elevation profiles from 2003-2006 collected over West Antarctica reveal numerous regions of temporally varying elevation. MODIS satellite imagery over roughly the same time period collaborates where these subglacial fluctuations have occurred. These observations have led scientists to conclude that subglacial water movement is happening in this lake region, revealing a widespread, dynamic subglacial water system that could provide important insights into ice flow and the mass balance of Antarctica's ice. |

ICESat First Light Release: From Sea Ice to Ice Streams |
| Abstract |
The following profile shows the dramatic change in elevation from coastal Antarctica, which is covered in sea ice for most of the year, to the center of the continent. It starts near the Amundsen Sea and travels inward, ending over the West Antarctic Ice Streams where we get a look at this dynamic portion of the polar landscape. (The green elevation profile in this animation is exaggerated vertically by a factor of 10x.) |

MODIS Mosaic of Antarctica view of Pine Island and Thwaites Glacier without ICESat Topography |
| Abstract |
NASA has released a digital image map of the Antarctic continent and surrounding islands. The Moderate Resolution Imaging Spectroradiometer (MODIS) Mosaic of Antarctica (MOA) image map is a composite of 260 swaths comprised of both Terra and Aqua MODIS images acquired between November 20, 2003 and February 29, 2004. MOA provides a cloud-free view of the ice sheet, ice shelves, and land surfaces at a grid scale of 125 m and an estimated resolution of 150 m. All land areas south of 60° S that are larger than a few hundred meters are included in the mosaic. Also included are several persistent fast ice areas and grounded icebergs. |

ICESat Aerosols over Africa |
| Abstract |
This is an animation showing data from ICESat's Geoscience Laser Altimeter System (GLAS). Aerosol data are shown spanning 80 passes over the Africa region from October 4 through October 28 2003. The data are initially shown in the time order collected using an 8 day moving time window. After that, the first 40 passes are all shown at once and a flown over. |

ICESat Cloud Walls (scripted camera path) |
| Abstract |
This is an animation showing data from ICESat's Geoscience Laser Altimeter System (GLAS). Cloud data can be seen over about 15 orbits on October 6, 2003. The data are initially laid out in the order that is was collected followed by continued movement around the scene. This version of the animation starts with the full globe, moves south to Antarctia, over the pole, then north to Africa, around the world near the equator and finally to the north pole. |
