    NASA Prepares for New Science Flights Above Coastal Louisiana

    Delta-X, a new NASA airborne investigation, is preparing to embark on its first field campaign in the Mississippi River Delta in coastal Louisiana. Beginning in April, the Delta-X science team, led by Principal Investigator Marc Simard of NASA's Jet Propulsion Laboratory in Pasadena, California, will be collecting data by air and by boat to better understand why some parts of the delta are disappearing due to sea-level rise while other parts are not.

    NASA Flights Detect Millions of Arctic Methane Hotspots

    The Arctic is one of the fastest warming places on the planet. As temperatures rise, the perpetually frozen layer of soil, called permafrost, begins to thaw, releasing methane and other greenhouse gases into the atmosphere. These methane emissions can accelerate future warming—but to understand to what extent, we need to know how much methane may be emitted, when and what environmental factors may influence its release.

    NASA Snow-Chasers Set to Fly Into East Coast Winter Storms

    This month NASA is sending a team of scientists, a host of ground instruments, and two research aircraft to study the inner workings of snowstorms. The Investigation of Microphysics Precipitation for Atlantic Coast-Threatening Snowstorms, or IMPACTS, has its first deployment in a multi-year field campaign from Jan. 17 through March 1. It will be the first comprehensive study of East Coast snowstorms in 30 years.

  • NASA to Study East Coast Snowstorms from VA. Skies

    NASA has announced it will use Wallops Island Flight Facility, just south of Chincoteague Island, as a jumping-off point to study Atlantic snowstorms starting in January.

    It’s the first major field campaign to study East Coast snowstorms in 30 years.

    The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) study will send a high-altitude aircraft (flying from Savannah, Georgia) and a cloud-sampling aircraft (flying from Wallops Island) to look closer at how snow is distributed in the clouds.

    NASA explains that the “cloud processes” responsible for snowstorms are difficult to measure, and forecast models can’t reproduce them very well. That makes for poor snowfall predictions.

    “People see pictures of these big swaths of clouds and think they’re snowing everywhere, but they’re not,” said IMPACTS principal investigator Lynn McMurdie at the University of Washington in Seattle. “Inside the clouds are these long narrow regions of more intense snow bands. We’re trying to understand why they form and how they evolve with the developing storm.”

    Since the last time East Coast snowstorms were studied from the air, instruments have become much more advanced. NASA says now is “an ideal time to conduct a well-equipped study to identify key processes and improve remote sensing and forecasting of snowfall.”

    NASA’s ER-2 and P-3 aircraft will fly for three six-week deployments.

    IceBridge Takes Flight from Down Under

    IceBridge has been gathering data on Arctic and Antarctic ice sheets, glaciers and sea ice for 10 years. It was designed to ‘bridge the gap’ in between the Ice, Cloud and land Elevation Satellite (ICESat), which stopped collecting data in 2009, and ICESat-2, which launched in September 2018. Over the past decade, IceBridge has been based out of airports in Alaska, Greenland, Chile, Argentina and Antarctica – but for this final polar campaign, it has a new base at Hobart in Tasmania, Australia.

  • 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.

    Study Predicts More Long-Term Sea Level Rise from Greenland Ice

    Greenland’s melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study. The study, which used data from NASA’s Operation IceBridge airborne campaign, was published in Science Advances today.

    Cold Water Currently Slowing Fastest Greenland Glacier

    NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. 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.

Though the newly found impact sites in northwest Greenland are only 114 miles apart, at present they do not appear to have formed at the same time.
