Mission Report (Michael Studinger, Mission Scientist)

This is a new mission, designed to accomplish a number of goals. First, we flew a radar tomography grid on the fast-flowing part of the Humboldt Glacier trunk, with 10 lines spaced at 2 km and 85 km long. We had to skip the part of a coastal flux line which connects with and is continued by the 2012 North Flux 01 mission because we had to land at 15:00 LT at Thule Air Base because of Saturday operations. Third, we flew a pair of historical ATM longitudinal lines down the trunk of the Petermann Glacier for dh/dt purposes. The central-most of these two was flown in 2010 and 2011, while the western line was last flown in 2002. The Petermann lines are extended 50 km farther inland than flown previously. We transit between Thule and between the survey areas on a combination of ICESat ground tracks and one master grid line immediately to the north of the Petermann grid established in 2010 and 2011. The MCoRDS radar was configured in tomographic mode (beamwidth +/- 35 deg, chirp length 10 us, one waveform with 10 us chirp) for the Humboldt grid, and in normal profiling mode for the rest of this flight. Flight elevation for the tomography portion was 800 m, or 2600 ft AGL. We skipped the westernmost ICESat line at the beginning of the flight to fly over sea ice at 10,000 ft AGL in order to do collect phase calibration data for MCoRDS for the tomography processing. We did +/- 25 degree rolls. We carefully choose a heading that did not have much impact on the GPS satellite coverage. We saw one spacecraft being shadowed by the left wing tip during rolls, but this space craft was so low above the horizon that it would likely be excluded from data processing anyway.

The weather in the survey area was perfect. We had to break off the last ICESat line near Thule over rocks due to clouds.

Near Petermann Gletscher we flew over one of the many plane wrecks that Greenland has, a reminder that safety is more important than anything else we do. The plane wreck near Petermann Glacier is a B-29 named Kee Bird, that crash landed there in 1947 (see photo below). The aircraft was repaired in 1995 and ready to be flown out. During taxi, the aircraft caught fire and burned down. PBS covered the repair attempt in a NOVA special in 1996.
 
Data collection started 12:02 UTC and ended at 16:56 UTC. We collected 4.9 hours of science data.
