MABEL: The ICESat-2 Demonstrator
01.28.11 – The Multiple Altimeter Beam Experimental Lidar (MABEL) has been developed to demonstrate the photon-counting altimetry approach chosen for the ICSat-2 mission. Operating from a high-altitude airborne platform, MABEL made initial demonstration flights last month. Matthew McGill, ICESat-2 instrument scientist, presented an overview of MABEL, its integration to NASA's ER-2, and initial results today at the SED Director's Seminar hosted by the Earth Sciences Division.

Scientists in the News
01.12.11 – Research and commentary by scientists appeared in numerous media outlets in recent months. Of particular interest was the Operation IceBridge mission, which received international coverage in both English and Spanish. Here are the highlights.
Puzzle of Antarctic Ice Melt Solved, December 15; Our Amazing Planet. Ted Scambos (NSIDC), Robert Bindschdler (NASA GSFC/GEST), and Michael Studinger (NASA GSFC/GEST) presented new findings at the fall meeting of the American Geophysical Union that revealed new pathways for ice loss in West Antarctica.
Antarctic Sea Ice Melting as Ocean Heat Rises, December 14; Discovery News. How fast West Antarctic ice will melt and in what locations depends largely on whether upwelling warm water comes in contact with the thick ice shelf that crowds the coast and holds back the glaciers from reaching the sea, which in turn depends on the winds which drive away the surface waters and make it possible for the deeper waters to rise to the surface, said Robert Bindschadler (NASA GSFC/UMBC).
A Glory-Ous Rainbow Over Antarctica, November 18; Our Amazing Planet. In an image taken Oct. 26 by Michael Studinger (NASA GSFC) over Antarctica's Brunt Ice Shelf, a glory surrounds the shadow of the DC-8 plane that is flying NASA's IceBridge mission to survey the state of Antarctic ice; the image was taken during the first flight of IceBridge's fall 2010 campaign.
How's Antarctica Faring? Experts Fly Over Ice to Find Out, November 15; MSNBC. Now in its second year, Operation IceBridge has been measuring ice at Earth's poles; Michael Studinger (NASA GSFC/UMBC), Chris Shuman (NASA GSFC/UMBC) and Seelye Martin (U. Washington) described the research flights over Antarctica during the 2010 field season.
Meltwater from Glaciers Could Warm Ice Even More, November 9; Our Amazing Planet. Researchers at the Colorado Center for Astrodynamics Research developed a model to show that meltwater flowing through cracks in glaciers and ice sheet spends more time inside the ice than scientists realized; Tom Neumann (NASA GSFC) said the new model introduces a possible mechanism to explain how changes in surface temperature can affect temperatures deep inside thick ice.
