Comments:Depart SCCI at 1229Z. Perform calibration ramp pass to the SE and overfly targets at 1235Z at 1500 ft AGL. Climb to cruise altitudes of FL310 & FL330. Descend to 1500 ft for initial part of low altitude data route for mission. Cross first science waypoint at 1532Z in the vicinity of Wirth Peninsula. Climb to 2000 ft AGL due to turbulence at 1612Z and complete remainder of low altitude route at that altitude. Six parallel ground tracks in roughly east/west direction flown covering the length of the glacier area. Complete mapping at 2056Z. Perform radar instrument calibration pitch maneuvers at 2056Z, 200 ft AGL, and then climb to FL390 for transit to Punta Arenas. Xchat with school children in class rooms across USA during mission. U.S. Ambassador to Chile, Alex Wolff, flew with us. Land SCCI at 2353Z.

Mission Summary: 

F09 Ferrigno Alison 01


  • Low-altitude survey (2,000 ft AGL) in the Ferrigno and Alison Ice Stream area.
  • Completed all planned survey lines.
  • Collected additional high altitude ATM and DMS data over sea ice in the Bellingshausen Sea during transits.
  • Conducted pitch maneuvers for time stamp verification of snow and Ku-band radars.
  • Conducted ramp pass (1,500 ft AGL) at Punta Arenas airport after takeoff for DMS, ATM, snow and Ku-band radar instrument calibration.
  • ATM, MCoRDS, snow and Ku-band radars, gravimeter, and DMS were operated on the survey lines.
  • Hosted several question and answer sessions on x-chat during the flight with students and teachers from the US. We're up to 495 students and 33 teachers total on this deployment.
  • Satellite Tracks: none
  • Repeat Mission: none

Mission Report (Michael Studinger, Mission Scientist)

Today, we flew 6 grid lines spaced 10 km apart along the coast covering the Ferrigno and Alison Ice Streams. The weather in the area was perfect. We slighlty adjusted our flight elevation from 1,500 ft AGL to 2,000 ft AGL to make for a smoother ride in the east of the survey area. This part of the grid experienced winds between 20 and 30 kts, causing significant amounts of wind-blown snow on the surface. The wind-blown snow did reduce the return signal strength of the ATM lasers, but the lasers were able to see the ice surface without problem. 

We flew a ramp pass at Punta Arenas airport at 1,500 ft AGL after takeoff to ensure data collection during daylight for DMS and ATM instrument calibration.

We hosted again several question and answer sessions on x-chat during the flight with students and teachers from across the United States.
