Topic: Glacier
The results provide insights into how the polar ice sheets are changing, demonstrating definitively that small gains of ice in East Antarctica are dwarfed by massive losses in West Antarctica. ![]() The Kangerdlugssup (pictured) and Jakobshavn glaciers in Greenland have lost roughly 14 to 20 feet (4 to 6 meters) of elevation per year over the past 16 years.

NASA Science continues from Home Offices, Video Conferencing in response to Coronavirus
With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to Coronavirus (COVID-19), the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers. «Read the rest of this article» Sections: Technology | No Comments
NASA study shows Denman Glacier vulnerable to Seawater Intrusion
Until recently, researchers believed East Antarctica was more stable than West Antarctica because it wasn’t losing as much ice compared to the glacial melt observed in the western part of the continent. ![]() This photograph shows ripples in the surface of Denman Glacier in East Antarctica that throw shadows against the ice. The glacier is melting at a faster rate now than it was from 2003 to 2008. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Operation IceBridge data shows Long-Term Sea Level Rise from Greenland Ice
The study, which used data from NASA’s Operation IceBridge airborne campaign, was published in Science Advances today. In the next 200 years, the ice sheet model shows that melting at the present rate could contribute 19 to 63 inches to global sea level rise, said the team led by scientists at the Geophysical Institute at the University of Alaska Fairbanks. ![]() The Greenland Ice Sheet is the second-largest body of ice in the world, covering roughly 650,000 square miles of Greenland’s surface. If it melts completely, it could contribute up to 23 feet of sea level rise, according to a new study using data from NASA’s Operation IceBridge.

NASA data reveals Greenland’s Jakobshavn Glacier has Grown for Third Straight Year
These images, produced using GLISTIN-A radar data as part of NASA’s Oceans Melting Greenland (OMG) mission, show how much mass the glacier gained from 2016-17, 2017-18 and 2018-19. ![]() These images show the mass Greenland’s Jakobshavn Glacier has gained from 2016-17, 2017-18 and 2018-19. Areas with the most growth – about 33 yards (30 meters) – are shown in dark blue. Red areas represent thinning. The images were produced using GLISTIN-A radar data as part of NASA’s Ocean’s Melting Greenland (OMG) mission.

NASA says Greenland’s fastest moving, fastest thinning Glacier is slowing, thickeningWritten by Carol Rasmussen
Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise – it continues to lose more ice to the ocean than it gains from snow accumulation – but at a slower rate. «Read the rest of this article» Sections: Technology | No Comments
NASA Finds Possible Second Impact Crater Under Greenland IceWritten By Maria-José Viñas
If the second crater, which has a width of over 22 miles, is ultimately confirmed as the result of a meteorite impact, it will be the 22nd largest impact crater found on Earth. ![]() Just 114 miles from the newly-found Hiawatha impact crater under the ice of northwest Greenland, lies a possible second impact crater. The 22-mile wide feature would be the second crater found under an ice sheet, and if confirmed, would be the 22nd-largest crater on Earth.

NASA study shows Thwaites Glacier in West Antarctica is disintegratingNASA Jet Propulsion Laboratory
The findings highlight the need for detailed observations of Antarctic glaciers’ undersides in calculating how fast global sea levels will rise in response to climate change. Researchers expected to find some gaps between ice and bedrock at Thwaites’ bottom where ocean water could flow in and melt the glacier from below. «Read the rest of this article» Sections: Technology | No Comments
NASA collects Meteorites in AntarcticaWritten by Bill Steigerwald
“There was just no sound; no air handling equipment, no leaves rustling, no bugs, no planes or cars. So quiet you just heard your heartbeat,” said Barbara Cohen, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Most of the time, however, there is a steady howl of bitter cold wind flowing down from the East Antarctic ice plateau. With a summer temperature hovering around zero Fahrenheit, “It’s the wind that makes you cold,” Cohen said. «Read the rest of this article» Sections: Technology | No Comments
NASA’s new simulator allows anyone to experiment with Sea Level ScienceWritten by Pat Brennan
Computer models are critical tools for understanding the future of a changing planet, including melting ice, rising seas and shifting precipitation patterns. But typically, these mathematical representations — long chains of computer code giving rise to images of dynamic change — are accessible mainly to scientists. «Read the rest of this article» Sections: Technology | No Comments
