On Nov. 4, 2012, Operation IceBridge flew an 11-hour mission over the Recovery Glacier and Filchner Ice Shelf in eastern Antarctica. On the transit back home, NASA scientist John Sonntag gave a two-minute breakdown of the mission over the aircraft headset, including the purpose of the day’s flight, the challenges of working with Antarctic weather forecasts, and what the team found when they arrived on site.

These missions gathered critical ice elevation and thickness data and gave those on the DC-8 spectacular views such as the Ellsworth Mountains—home of Antarctica's highest point, Vinson Massif (16,067 feet)—and the rift in the Pine Island Glacier that was discovered during last year's Antarctic campaign.

In the evening before every flight, mission planners decide on several options for the next day. This takes into account changes in the Antarctic weather that seem to happen with little notice. In this case, clouds over the Weddell Sea meant selecting high priority missions to survey sea ice in the Bellingshausen Sea and map ice streams in Recovery Glacier.

Over the next two days, IceBridge scientists carried out two more high priority land-ice flights, one over the Foundation Ice Stream and one over Thwaites Glacier. As earlier, plans to survey sea ice were put on temporary hold due to unfavorable weather conditions in the region.
