Comments:Depart SCCI at 1517Z. Did not perform calibration ramp pass due to low overcast weather conditions. Climb to cruise altitudes of FL330 to FL350. Perform gravity data line at FL350 starting earlier than initial point at 1738Z, cross original gravity line start waypoint at 1802Z, start descent at 1901Z, and ending 1922Z. Cross first low altitude science waypoint at 1922Z at 1500 ft. Continue to fly ground track pattern of six parallel lines over Filchner Ice Shelf. Pass over final low altitude waypoint at 2201Z. Perform radar pitch maneuvers at 2000 ft AGL at 2104Z. Perform second high altitude gravity line starting at climb north bound at 2202Z and ending at 2311Z at FL400. High altitude ATM data collected during transit segments. Climb to FL400 for transit to Punta Arenas. Land SCCI at 0153Z.

Mission Report (Michael Studinger, Mission Scientist)

This morning a familiar pattern repeated itself again: a desperate look into the weather conditions over the Weddell Sea followed by the conclusion that a science mission over the Weddell Sea is a no go today. At least we were able to choose one of the remaining high-priority land ice missions with regional high priority.

Before starting engines an issue with one of the fuel gage indicators was identified. The crew was able to quickly locate the cause for the problem and replaced the fuse in the power supply of the fuel gage indicator. Thanks to such an experienced and dedicated crew we were able to take off with only a one hour delay, which allowed us to complete the entire survey as planned. Great job everyone!   

The weather in the target area was what we had expected from the model forecast. Shortly before takeoff we downloaded the latest MODIS satellite image (Fig. 2). The image showed two layers of clouds in the area, with the colors and shadows indicating that one layer was high with an intermediate layer below. The satellite image was acquired roughly 15 hours before we reached the survey area. Based on the satellite image and the model forecast we felt confident that we could work below the two layer of clouds. The conditions in the area were exactly what we had expected and we were able to complete the entire survey as planned and only had to climb for the last 2 minutes due to clouds below us.

We hosted a question and answer session on x-chat with a school from Punta Arenas.
