UNSTABLE ANTARCTICA: WHAT’S DRIVING ICE LOSS?
New results based on data from airborne and satellite missions show a clear picture of mechanisms driving ice loss in West Antarctica. Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear. Now, using data from a range of NASA’s Earth observing satellites and from the ongoing Operation IceBridge airborne mission, scientists have pinpointed ice loss culprits above and below the ice. Continued monitoring of Antarctica’s rapidly changing areas is expected to improve predictions of sea level rise. Related Sessions: C22B, C13D, C11A, C44A

West Antarctica is seeing dramatic ice loss particularly the Antarctic Peninsula and Pine Island regions. Ice loss culprits include the loss off buttressing ice shelves, wind, and a sub-shelf channel that allows warm water to intrude below the ice. Credit: NASA/NSIDC
