NASA’s Operation IceBridge Surveys Greenland and Earth’s Polar Ice Sheets

NASA’s Operation IceBridge has begun the 2013 research season of Ice Science flights in Greenland and the Arctic to survey the regions ice sheets and land and sea ice using a specially equipped P-3B research aircraft from NASA’s Wallops Flight Facility in Wallops Island, Va.

Operation IceBridge began in 2009 as part of NASA’s six-year long effort to conduct the largest airborne survey of Earth’s polar ice ever flown.

The goal is to obtain an unprecedented three-dimensional, multi-instrument view of the behavior of Greenland, Arctic and Antarctic ice sheets, ice shelves and sea ice which have been undergoing rapid and dramatic changes and reductions.

“We’re starting to see how the whole ice sheet is changing,” said Michael Studinger, IceBridge project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “Thinning at the margins is now propagating to the interior.”

The airborne campaign was started in order to maintain a continuous record of measurements in changes in polar ice after NASA’s Earth orbiting ICESat (Ice, Cloud and Land Elevation Satellite) probe stopped collecting data in 2009.

ICESat-2 won’t be launched until 2016, so NASA’s IceBridge project and yearly P-3 airborne campaigns will fill in the science data gap in the interval.

IceBridge is operating out of airfields in Thule and Kangerlussuaq, Greenland, and Fairbanks, Alaska.

The P-3B survey flights over Greenland and the Arctic will continue until May. They are conducted over Antarctica during October and November.

The measurements collected by IceBridge instruments will characterize the annual changes in thickness of sea ice, glaciers, and ice sheets. The data are used to help predict how climate change affects Earth’s polar ice and the resulting rise in sea-levels.

Researchers with the U.S. Army Corps of Engineers are collaborating with the IceBridge project to collect snow depth measurements near Barrow , Alaska. High school science teachers from the US, Denmark and Greenland will fly along on the P-3B survey flights to learn about polar science.

NASA Wallops has a wide ranging research and development mission and is home to the Virginia launch pad for the new Antares/Cygnus commercial ISS resupply rocket set for its maiden launch in mid April 2013; detailed in see my new story - here.
