Mission Summary: 

F10 Getz Ice Shelf #07


  • Low-altitude survey (1,500 ft AGL) upstream of the Getz Ice Shelf in Marie Byrd Land.
  • Completed all planned survey lines.
  • ATM, MCoRDS, snow and Ku-band radars, gravimeter, and DMS were operated on the survey lines.
  • Collected additional ATM and DMS high-altitude data over sea ice during transit.
  • Conducted pitch maneuvers for time stamp verification of snow and Ku-band radars.
  • Conducted ramp pass (1,000 ft AGL) at Punta Arenas airport after takeoff for DMS, ATM, snow and Ku-band radar instrument calibration.
  • Satellite Tracks: none
  • Repeat Mission: partial repeat of 2011 NCAR G-V surface altimetry with LVIS

Mission Report (Michael Studinger, Mission Scientist)

The forecast for all remaining high priority missions in high priority areas remained poor today and we chose the mission with the next highest priority on the list that indicated suitable weather conditions for a science flight. The forecast for the Getz Ice Shelf area and Marie Byrd Land looked good. The western end of the survey area was close to a system that was moving in, but we were fairly confident from satellite images and models that we would only encounter the high clouds that are ahead of the bad weather. We encountered excactly the conditions that we had expected and we were able to complete all planned survey lines at low altitude. In addition we recorded high altitude data over sea ice during the transits to and from the main survey area.

The Getz #07 mission is a new design. Its purpose is to supplement the IceBridge missions flown between 2009-2011 over the Getz Ice Shelf and upstream. The goals are to continue mapping the sub ice-shelf bathymetry using gravity data, and to continue mapping the ice surface and bedrock upstream of the grounding line. This particular flight focuses on the area inboard of the grounding line, and it includes a tie line for leveling all existing gravity profiles that we have flow. The two coast-parallel lines are a dh/dt repeat of two lines that have been surveyed from high altitude with the NCAR G-V and LVIS in 2011.

We also completed a ramp pass at Punta Arenas airport at 1,000 ft AGL after takeoff to ensure data collection during daylight for DMS and ATM instrument calibration and also for snow and Ku-band radar calibration.
