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": 174 }, { "id": 13471, "url": "https://svs.gsfc.nasa.gov/13471/", "result_type": "Produced Video", "release_date": "2019-12-09T14:00:00-05:00", "title": "Operation IceBridge - Icebergs", "description": "Icebergs start as land ice—snow that has accumulated on land and, over the course of many years, has been compacted into ice.

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 advance and retreat of the front of this ~35-kilometer (~22-mile) wide outlet glacier can be seen in this 6-day interval image series. The rapid flow of inland ice causes the glacier front to advance and two major calving events cause the ice front to retreat.Combined, the 2015 and 2017 calving events have led to the glacier’s ice front being fully disconnected from the North Ice Shelf. The changes to this large outlet from West Antarctica could signal additional sea level contributions from this glacier and the even larger outlet to the west, Thwaites Glacier.Credit: Stef Lhermitte, Delft University of Technology, NetherlandsContains modified Copernicus Sentinel data (2017), processed by ESA || pine_island_1080p.00001_print.jpg (1024x576) [180.8 KB] || pine_island_1080p.00001_searchweb.png (320x180) [98.2 KB] || pine_island_1080p.00001_thm.png (80x40) [6.7 KB] || pine_island_1080p.mp4 (1920x1080) [54.5 MB] || pine_island_720p.mp4 (1280x720) [26.3 MB] || pine_island_1080p.webm (1920x1080) [5.0 MB] || 4104x2304_16x9_30p (4104x2304) [0 Item(s)] || pine_island_2304p.mp4 (4096x2304) [156.5 MB] || ", "hits": 175 }, { "id": 12666, "url": "https://svs.gsfc.nasa.gov/12666/", "result_type": "Produced Video", "release_date": "2017-08-11T16:00:00-04:00", "title": "Scientists Bury GPS in Antarctic Ice to Measure Effects of Tides", "description": "NASA scientists and ice sheet modelers, Ryan Walker and Christine Dow, traveled to a remote location on the coast of Antarctic to investigate how tides affect the movement and stability of the Nansen Ice Shelf, a 695-mile extension of ice protruding into Antarctica’s Ross Sea.

By tracking displacement of local surface features through the seasons on outlet glaciers from the large ice sheets, researchers from the University of Alaska, the University of Bristol, and the University of Colorado have been able to show that each glacier around Greenland has a unique pattern of flow variation through the seasons. 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.

In a paper in April, Rignot's research group discussed the steadily increasing flow speeds of these glaciers over the past 40 years. This new study examines the other two lines of evidence.As glaciers flow out from land to the ocean, large expanses of ice behind their leading edges float on the seawater. The point on a glacier where it first loses contact with land is called the grounding line. Nearly all glacier melt occurs on the underside of the glacier beyond the grounding line, on the section floating on seawater. The Antarctic glaciers studied have thinned so much they are now floating above places where they used to sit solidly on land, which means their grounding lines are retreating inland.—>
