Mission Report (Michael Studinger, Mission Scientist)

Today we flew 6 grid lines spaced 20 km apart over the grounding line area of the Foundation Ice Stream. The weather conditions in the Weddell Sea forced us again to fly a land ice mission, but at least we were able to choose a high priority mission with regional high priority. The weather in the Foundation Ice Stream area was perfect. We only experienced some occasional moderate to light turbulence. We collected an additional 2.9 hours of high altitude data with ATM and DMS on the transits with beautiful and rare views of the Antarctica Peninsula.

We flew a ramp pass at Punta Arenas airport at 2,000 ft AGL after takeoff to ensure data collection during daylight for DMS and ATM instrument calibration.
