            "description": "<!——><!—Above: Move bar to compare the bedrock topography (left) to the ice sheet surface (right).Download HTML to embed this in your web page.The topography of the bedrock under the Antarctic Ice Sheet is critical to understanding the dynamic motion of the ice sheet, its thickness and its influence on the surrounding ocean and global climate. In 2001, the British Antarctic Survey (BAS) released a map of the bed under the Antarctic Ice Sheet and the seabed extending out on to the continental shelf derived from data collected by an international consortium of scientists over the prior fifty years. The resulting dataset was called BEDMAP (or BEDMAP1).In 2013, BAS released an update of the topographic dataset called BEDMAP2 that incorporates twenty-five million measurements taken over the past two decades from the ground, air and space. This visualization compares the new BEDMAP2 dataset to the original BEDMAP1 dataset showing the improvements in resolution and coverage. <!——><!—Above: Move bar to compare the Bedmap1 topography (left) to the Bedmap2 topography (right). Download HTML to embed this in your web page.Since 2009, NASA's mission Operation IceBridge (OIB) has flown aircraft over the Antarctic Ice Sheet carrying laser and ice-penetrating radar instruments to collect data about the surface height, bedrock topography and ice thickness. This visualization highlights the contribution that OIB has made to this important dataset.The topography in this visualization is exaggerated to emphasize the topographic relief. The amount of exaggeration varies based on the viewpoint, from twenty times in distant views down to nine times when near the Pine Island Bay. || ",

            "description": "Operation IceBridge — a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice — is soon to embark on its fourth field season in October. 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. || ",
