IceBridge utilizes a highly specialized fleet of research aircraft and the most sophisticated suite of innovative science instruments ever assembled to characterize annual changes in thickness of sea ice, glaciers, and ice sheets. In addition, IceBridge collects critical data used to predict the response of earth’s polar ice to climate change and resulting sea-level rise. IceBridge also helps bridge the gap in polar observations between NASA’s ICESat satellite missions.The below clips represent a miscellaneous collection of instruments used during the Arctic campaigns. || ", "hits": 14 }, { "id": 4706, "url": "https://svs.gsfc.nasa.gov/4706/", "result_type": "Visualization", "release_date": "2019-07-28T00:00:00-04:00", "title": "Greenland's Hiawatha Crater", "description": "This visualization shows the location of the Hiawatha Glacier near Inglefield Land in northwest Greenland. The surface of the ice sheet fades away to show the impact crater discovered beneath the ice sheet. A red cylinder shows the best-fit rim of the impact crater and a measuring stick shows that the diameter of the crater is more than 31 kilometers across. The size of the crater is compared to the cities of Washington, DC and Paris, France.The visualization also shows how the scientists from Germany's Alfred Wegener Institute (AWI) flew the Polar 6 aircraft (a DC-3T) to collect radar data over the Hiawatha impact crater. The radar data is shown in detail as curtains of the radar data are dissolved away to display the layers of the ice sheet in the interior of the crater. || Hiawatha.0590_print.jpg (1024x576) [150.4 KB] || Hiawatha.0590_searchweb.png (320x180) [88.4 KB] || Hiawatha.0590_thm.png (80x40) [6.2 KB] || 4706_Hiawatha_Crater.webmhd.webm (1080x606) [23.5 MB] || 4706_Hiawatha_Crater.mp4 (1920x1080) [228.6 MB] || 3840x2160_16x9_30p (3840x2160) [0 Item(s)] || 4706_Hiawatha_Crater.en_US.vtt [2.1 KB] || 4706_Hiawatha_Crater.en_US.srt [2.0 KB] || Hiawatha_Prores_4k.mp4 (3840x2160) [566.2 MB] || 4706_Hiawatha_Crater.mov (1920x1080) [1.9 GB] || Hiawatha_Prores_4k.mov (3840x2160) [7.6 GB] || ", "hits": 56 }, { "id": 13146, "url": "https://svs.gsfc.nasa.gov/13146/", "result_type": "Produced Video", "release_date": "2019-02-11T11:00:00-05:00", "title": "NASA Finds Second Massive Greenland Crater", "description": "Text-on-screen video about a possible new impact crater under Greenland's ice || C2_TOS_Final.00768_print.jpg (1024x576) [142.6 KB] || C2_TOS_Final.00768_searchweb.png (180x320) [98.7 KB] || C2_TOS_Final.00768_thm.png (80x40) [7.3 KB] || C2_TOS_Final.mp4 (1920x1080) [67.0 MB] || C2_TOS_Final.webm (1920x1080) [6.9 MB] || C2_TOS_Final.en_US.srt [1.2 KB] || C2_TOS_Final.en_US.vtt [1.2 KB] || ", "hits": 40 }, { "id": 4572, "url": "https://svs.gsfc.nasa.gov/4572/", "result_type": "Visualization", "release_date": "2018-11-14T14:00:00-05:00", "title": "The Hiawatha Impact Crater", "description": "The series of visualizations below are derived from satellite imagery and radar sounding. They portray both the location and size of the 31-kilometer-wide impact crater beneath Hiawatha Glacier. They also portray the structure of the glacier ice that flows into and fills the crater.The Hiawatha impact crater was first suspected to exist in the summer of 2015, from examination of a compilation of Greenland's sub-ice topography radar measurements made by NASA over two decades. The visualizations of the subsurface shown below are derived from a spring 2016 airborne survey by Germany's Alfred Wegener Institute, using a new ultrawideband radar sounder developed by the Center for Remote Sensing of Ice Sheets at The University of Kansas. Subsequent helicopter visits to the deglaciated terrain in front of Hiawatha Glacier by scientists from the Natural History Museum in Denmark recovered sediment samples from the main river that discharges water from beneath Hiawatha Glacier, through the northwestern rim breach. Laboratory examination revealed that these sediment samples contained shocked quartz and elevated platinum-group-element concentrations, both signs that the sediment records evidence of the impact of an iron asteroid more than one kilometer wide. The Hiawatha impact crater is potentially one of the youngest large impact craters on Earth.In the visualizations below, the elevation of the topography of the bed, the ice surface and the radar curtains have been exaggerated ten times in order to better illustrate their structure. || ", "hits": 192 }, { "id": 12941, "url": "https://svs.gsfc.nasa.gov/12941/", "result_type": "Produced Video", "release_date": "2018-11-14T13:50:00-05:00", "title": "Massive Crater Discovered under Greenland Ice", "description": "It took the combined efforts of an international team of scientists to unravel the mystery of the Hiawatha crater.
