Jakobshavn is Greenland’s fastest-moving glacier, and the flow rate is variable with spurts of speed in the summer and additional variation from year to year.When an ice tongue such as the Jakobshavn calves, the glacier feeding that ice tongue typically accelerates. Reduced friction between the intact glacier and the bedrock, and reduced buoyancy from the seawater (which partially offsets the glacier’s downhill flow) mean less resistance to glacier movement. Warming conditions in the Arctic contribute to glacier acceleration in multiple ways. Warmer conditions can send meltwater to the glacier’s base, increasing lubrication and consequently glacier speed. During the winter, the rate of iceberg calving usually slows significantly; the glacier tongue advances, and its flow speed drops. Warm winters, however, may allow iceberg calving and high flow rates to continue.Since 2000, Greenland has lost some 739 gigatons of ice, and approximately 30 percent of that loss came from Jakobshavn and four other glaciers || ", "hits": 32 }, { "id": 13472, "url": "https://svs.gsfc.nasa.gov/13472/", "result_type": "Produced Video", "release_date": "2019-12-09T14:00:00-05:00", "title": "Operation IceBridge - Northern Greenland", "description": "4K B-roll of snowy northern Greenland landscape filmed during the 2016 Arctic campaign.

Rising atmosphere and ocean temperatures have led to an ice loss equivalent to over a centimeter increase in global mean sea-level between 1991 and 2015. Large outlet glaciers, rivers of ice moving to the sea, drain the ice from the interior of Greenland and cause the outer margins of the ice sheet to recede. Improvements in measuring the ice thickness in ice sheets is enabling better simulation of the flow in outlet glaciers, which is key to predicting the retreat of ice sheets into the future.Recently, a simulation of the effects of outlet glacier flow on ice sheet thickness coupled with improved data and comprehensive climate modeling for differing future climate scenarios has been used to estimate Greenland’s contribution to sea-level over the next millennium. Greenland could contribute 5–34 cm (2-13 inches) to sea-level by 2100 and 11–162 cm (4-64 inches) by 2200, with outlet glaciers contributing 19–40 % of the total mass loss. The analysis shows that uncertainties in projecting mass loss are dominated by uncertainties in climate scenarios and surface processes, followed by ice dynamics. Uncertainties in ocean conditions play a minor role, particularly in the long term. Greenland will very likely become ice-free within a millennium without significant reductions in greenhouse gas emissions.Three visualizations of the evolution of the Jakobshavn region of the Greenland Ice Sheet between 2008 and 2300 based on three different climate scenarios are shown below.

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 heat, accompanied by moist air, is entering the Arctic not only through the sector of the North Atlantic Ocean that lies between Greenland and Europe, as it has done in previous years, but is also coming from the North Pacific through the Bering Strait. “We have seen winter warming events before, but they’re becoming more frequent and more intense,” said Alek Petty, a sea ice researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Scientists are waiting to see how much this heat wave will impact the wintertime sea ice maximum extent, which has been shrinking in the past decades and has hit record lows each of the past three years. The sea ice levels are already at record lows or near-record lows in several areas of the Arctic. Another exceptional event this winter is the opening up of the sea ice cover north of Greenland, releasing heat from the ocean to the atmosphere and making the sea ice more vulnerable to further melting. “This is a region where we have the thickest multi-year sea ice and expect it to not be mobile, to be resilient,” Petty said. “But now this ice is moving pretty quickly, pushed by strong southerly winds and probably affected by the warm temperatures, too.” || ", "hits": 20 }, { "id": 12849, "url": "https://svs.gsfc.nasa.gov/12849/", "result_type": "Produced Video", "release_date": "2018-02-13T09:00:00-05:00", "title": "Sea Level Rise Accelerates Over Time", "description": "Music: Contemporary Art Daily by Laurent Dury [SACEM]Complete transcript available. || Screen_Shot_2018-02-09_at_2.43.17_PM.png (1670x937) [935.6 KB] || Screen_Shot_2018-02-09_at_2.43.17_PM_print.jpg (1024x574) [63.9 KB] || Screen_Shot_2018-02-09_at_2.43.17_PM_searchweb.png (320x180) [45.9 KB] || Screen_Shot_2018-02-09_at_2.43.17_PM_thm.png (80x40) [4.1 KB] || 12849_SLR_Final.webm (960x540) [27.5 MB] || 12849_SLR_Final_appletv.m4v (1280x720) [37.4 MB] || YOUTUBE_1080_12849_SLR_Final_youtube_1080.mp4 (1920x1080) [107.4 MB] || 12849_SLR_Final_large.mp4 (1920x1080) [69.8 MB] || 12849_SLR_Final_appletv_subtitles.m4v (1280x720) [37.4 MB] || SLR_NoText.mp4 (1918x1080) [68.1 MB] || SLR_Acceleration.en_US.srt [958 bytes] || SLR_Acceleration.en_US.vtt [971 bytes] || ", "hits": 238 }, { "id": 12860, "url": "https://svs.gsfc.nasa.gov/12860/", "result_type": "Produced Video", "release_date": "2018-02-13T09:00:00-05:00", "title": "Big Year for NASA’s IceBridge in 2017", "description": "All seven campaigns are captured in this highlight video. || Big_Year_OIB_2017_final_web.00840_print.jpg (1024x576) [100.5 KB] || Big_Year_OIB_2017_final_web.00840_thm.png (80x40) [5.1 KB] || Big_Year_OIB_2017_final_web.00840_searchweb.png (320x180) [60.4 KB] || Big_Year_OIB_2017_final_web.00840_web.png (320x180) [60.4 KB] || Big_Year_OIB_2017_final.mov (1920x1080) [5.5 GB] || Big_Year_OIB_2017_final_web.mp4 (1920x1080) [213.4 MB] || Big_Year_OIB_2017_final.webm (1920x1080) [22.8 MB] || Big_Year_OIB_2017_final_web.en_US.srt [1.6 KB] || Big_Year_OIB_2017_final_web.en_US.vtt [1.6 KB] || ", "hits": 13 }, { "id": 12830, "url": "https://svs.gsfc.nasa.gov/12830/", "result_type": "Produced Video", "release_date": "2018-01-18T12:00:00-05:00", "title": "Dr. Piers Sellers in Greenland", "description": "A short video featuring Dr. Sellers' views on Greenland, climate, and IceBridge. || Piers_OIB_3_1.00240_print.jpg (1024x576) [19.3 KB] || Piers_OIB_3_1.00240_searchweb.png (320x180) [9.7 KB] || Piers_OIB_3_1.00240_thm.png (80x40) [1.5 KB] || Piers_OIB_3_1.mov (1280x720) [211.9 MB] || Piers_OIB_3_1.webm (1280x720) [8.5 MB] || Piers_OIB.en_US.srt [1.4 KB] || Piers_OIB.en_US.vtt [1.4 KB] || ", "hits": 18 }, { "id": 30882, "url": "https://svs.gsfc.nasa.gov/30882/", "result_type": "Hyperwall Visual", "release_date": "2017-06-07T12:00:00-04:00", "title": "Breakdown of an Ice Arch", "description": "Ice arch collapse at the Nares Strait || ice_arch_collapse_lincoln_print.jpg (1024x574) [137.9 KB] || ice_arch_collapse_lincoln.png (4104x2304) [11.1 MB] || ice_arch_collapse_lincoln_searchweb.png (320x180) [90.7 KB] || ice_arch_collapse_lincoln_thm.png (80x40) [6.3 KB] || breakdown-of-an-ice-arch.hwshow [298 bytes] || ", "hits": 18 }, { "id": 12608, "url": "https://svs.gsfc.nasa.gov/12608/", "result_type": "Produced Video", "release_date": "2017-05-17T11:00:00-04:00", "title": "IceBridge tackles Svalbard, North Pole, and Greenland in One Day", "description": "Complete transcript available. || Zigzag_East_final_youtube.00480_print.jpg (1024x576) [170.1 KB] || Zigzag_East_final_youtube.00480_searchweb.png (180x320) [108.4 KB] || Zigzag_East_final_youtube.00480_web.png (320x180) [108.4 KB] || Zigzag_East_final_youtube.00480_thm.png (80x40) [7.7 KB] || Zigzag_East_final_youtube.mp4 (1920x1080) [257.3 MB] || Zigzag_East_final.mov (1920x1080) [3.2 GB] || Zigzag_East_smaller.mov (1280x720) [1.6 GB] || Zigzag_East_smaller.webm (1280x720) [26.3 MB] || Zigzag_East_final_youtube.en_US.srt [4.2 KB] || Zigzag_East_final_youtube.en_US.vtt [4.1 KB] || ", "hits": 30 }, { "id": 30879, "url": "https://svs.gsfc.nasa.gov/30879/", "result_type": "Hyperwall Visual", "release_date": "2017-05-02T00:00:00-04:00", "title": "Greenland Ice Loss 2002-2016", "description": "The mass of the Greenland ice sheet has rapidly declined in the last several years due to surface melting and iceberg calving.

Seasonal variations, seen in this animation on the lower 25 kilometers of Heimdal Glacier in southeast Greenland, are caused by a combination of processes. For Heimdal, the largest forcing for flow variation is likely the input of increasing amounts of surface melt water through the Spring and Summer, but there is also an interplay between calving of ice from the end of the glacier, flow acceleration as shown in the animation, and thinning of the ice due to the extra stretching from the faster flow. By measuring these changes in flow on seasonal timescales, scientists can develop a better understanding of what controls the flow of these glaciers where they meet the ocean.

This visualization shows the sea level change between 1992 and 2014. Since 1992, seas around the world have risen an average of nearly 3 inches. Regional differences in sea levels are caused by ocean currents and natural long-term ocean cycles.2. Scientists estimate one-third of the ocean rise is caused by the melting of the Greenland and Antarctic ice shelves. The big concern now is that the ice sheets are ‘waking up’ to the warming climate and will contribute more and more to sea level rise in the coming decades.3. An intense research effort by NASA and others is now underway to measure and analyze how Greenland and Antarctica will respond to Earth's warmer air temperatures and the changing ocean currents along the edges of the ice shelves.TAG: Faster melting of the polar ice caps could mean sea rise of 3 feet or more by the end of the century. || NASAONAIR_Sea_Level_Rise-10-iPad3_print.jpg (1024x576) [92.3 KB] || NASAONAIR_Sea_Level_Rise-10-iPad3_searchweb.png (320x180) [67.4 KB] || NASAONAIR_Sea_Level_Rise-10-iPad3_thm.png (80x40) [5.9 KB] || NASAONAIR_Sea_Level_Rise-1_Weather_Channel_30_fps.mov (1920x1080) [493.1 MB] || NASAONAIR_Sea_Level_Rise-2_Weather_Channel_60_fps.mov (1280x720) [592.5 MB] || NASAONAIR_Sea_Level_Rise-3_NBC_Today.mov (1920x1080) [232.3 MB] || NASAONAIR_Sea_Level_Rise-4-WeatherChannel.wmv (1280x720) [8.8 MB] || NASAONAIR_Sea_Level_Rise-5-Accuweather.avi (1280x720) [6.7 MB] || NASAONAIR_Sea_Level_Rise-6_Baron_Services_MP4.mp4 (1920x1080) [23.8 MB] || NASAONAIR_Sea_Level_Rise-7_APR_422_1920_30.mov (1920x1080) [464.0 MB] || NASAONAIR_Sea_Level_Rise-8-iPad1.m4v (960x540) [13.7 MB] || NASAONAIR_Sea_Level_Rise-9-iPad2.m4v (1280x720) [7.2 MB] || NASAONAIR_Sea_Level_Rise-10-iPad3.m4v (1920x1080) [7.2 MB] || NASAONAIR_Sea_Level_Rise-10-iPad3.webm (1920x1080) [3.4 MB] || ", "hits": 41 }, { "id": 11987, "url": "https://svs.gsfc.nasa.gov/11987/", "result_type": "Produced Video", "release_date": "2015-08-26T15:45:00-04:00", "title": "Greenland Icebergs", "description": "GreenlandReel_Icebergs_720H264_print.jpg (1024x576) [90.9 KB] || GreenlandReel_Icebergs_720H264_searchweb.png (320x180) [85.7 KB] || GreenlandReel_Icebergs_720H264_web.png (180x320) [85.7 KB] || GreenlandReel_Icebergs_720H264_thm.png (80x40) [5.7 KB] || GreenlandReel_Icebergs_720H264.mp4 (1280x720) [466.5 MB] || GreenlandReel_Icebergs_1080H264.mp4 (1920x1080) [467.9 MB] || GreenlandReel_Icebergs_720H264.webm (1280x720) [29.8 MB] || GreenlandReel_Icebergs_2160H264.mp4 (3840x2160) [1.1 GB] || GreenlandReel_Icebergs_2160APR.mov (3840x2160) [30.8 GB] || ", "hits": 24 }, { "id": 4325, "url": "https://svs.gsfc.nasa.gov/4325/", "result_type": "Visualization", "release_date": "2015-08-26T10:00:00-04:00", "title": "NASA GSFC MASCON Solution over Greenland from Jan 2004 - Jun 2014", "description": "Visualization of the mass change over Greenland from January 2004 through June 2014.

Recent analysis of seven years of surface elevation readings from NASA's ICESat satellite and four years of laser and and ice-penetrating radar data from NASA's airborne mission Operation IceBridge shows us how the surface elevation of the ice sheet has changed.The colors shown on the surface of the ice sheet represent the accumulated change in elevation since 2003. The light yellow over the central region of the ice sheet indicates a slight thickening due to snow. This accumulation, along with the weight of the ice sheet, pushes ice toward the coast. Thinning near coastal regions, shown in green, blue and purple, has increased over time and now extends into the interior of the ice sheet where the bedrock topography permits. As a result, there has been an average loss of 300 cubic kilometers of ice per year between 2003 and 2012.This animation portrays the changes occurring in the surface elevation of the ice sheet since 2003 in three drainage regions: the southeast, the northeast and the Jakobshavn regions. In each region, the time advances to show the accumulated change in elevation from 2003 through 2012.—>
