Operation IceBridge, NASA's longest-running airborne mission to monitor polar ice change, concluded this year's springtime survey of Arctic sea and land ice on May 2.

According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began.
