05.16.13 - 99% of all of Earth’s land ice is locked into the Greenland and Antarctic ice sheets. But from 2003 to 2009, the world’s other glaciers contributed just as much to sea level rise as the two ice sheets combined.
05.01.13 - NASA will test a new robotic explorer, dubbed GROVER, in Greenland from early May to early June 2013.
04.01.13 - Nathan Kurtz is a physical scientist working with NASA's Operation IceBridge.
04.03.13 - The Arctic Ocean's icy cover reached its annual maximum extent on February 28. At 5.82 million square miles, the 2013 sea ice winter extent is the fifth lowest in the satellite era.
12.19.12 - Sea ice thickness data gathered in April 2012 by NASA's Operation IceBridge has been used in seasonal sea ice forecasts for the first time.
11.12.12 - While Arctic sea ice cover is declining dramatically under the effects of climate change, Antarctic sea ice cover has increased in recent years. A new study examines why.
10.23.12 - While the Arctic Ocean ice cap has diminished over the last three decades, the sea ice cover at the opposite pole of the planet has expanded.
10.15.12 - The rift in Antarctica's Pine Island Glacier that was discovered by NASA's Operation IceBridge in 2011 has been monitored by researchers around the world.
10.11.12 - Two weeks after a record low sea ice minimum in the Arctic Ocean, the ice around Antarctica reached its annual winter maximum—and set a record for a new high.
09.19.12 - The floating, frozen sea ice covering the Arctic Ocean melted to a record low extent on Sept. 16, 2012, continuing a long-term trend that has seen the summer size of the ice cap shrink dramatically in the past three decades.
09.17.12 - Over the next few weeks, an ER-2 high altitude research aircraft will take part in the development of two future satellite instruments.
08.27.12 - The declining sea ice in the Arctic Ocean has melted down to its smallest size since satellite observations began in the late 1970s. The current size of the polar cap surpassed the previous record set in 2007.
07.24.12 - For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations.
07.23.12 - In 2007, more than 1,100 Landsat 7 images were used to create the first ever, high-resolution, true color map of Antarctica. The Landsat Image Mosaic of Antarctica is a virtually cloud-free, 3-D view of Antarctica's frozen landscape.
06.17.12 - A new study with NASA participation finds ancient Antarctica's climate was much warmer and wetter than previously suspected, supporting substantial vegetation along its edges.
06.07.12 - Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rain forest in the middle of a desert.
05.01.12 - The weather, the aircraft and the science instruments cooperated to successfully validate data from the MABEL laser altimeter planned for IceSat-2.
04.25.12 - Warm ocean currents attacking the underside of ice shelves are the dominant cause of recent ice loss from Antarctica, based on data from ICESat.
04.03.12 - A NASA ER-2 Earth science aircraft has arrived in Keflavik, Iceland, to begin a series of flights to confirm the accuracy of a new laser altimeter.
03.15.12 - A NASA ER-2 Earth Resources aircraft will fly a number of high-altitude missions this spring to validate the accuracy of a new laser altimeter.› View Photos
