In Images: IceBridge Investigates Antarctica

Operation IceBridge

NASA's Operation IceBridge is a six-year mission to survey land and sea ice at the poles. The program's DC-8 research plane, loaded with remote-sensing equipment, captured spectacular images of Antarctica's mountains and glaciers in October 2012, the first half of this year's campaign. Combining new measurements with previously gathered data gives researchers a more detailed view of ice dynamics. The resulting information will help improve computer models that predict how ice sheets change over time.

This complex mixture of Antarctic sea ice was photographed on Oct. 13 in the Bellingshausen Sea with the Digital Mapping System (DMS) onboard the IceBridge research plane. Different types of sea ice in the Southern Ocean include dark black (open water), a thin grease-like covering (grease ice), and thicker grey ice.

An iceberg embedded in sea ice in the Bellingshausen Sea, photographed from the IceBridge research plane on Oct. 19. "Thickness in the Bellingshausen has increased slightly while area has decreased. We're looking at why that is," said sea ice scientist Nathan Kurtz of NASA's Goddard Space Flight Center.
