Mission Summary: 

F15 Weddell Sea - Twisted


  • Low-altitude survey (1,500 ft AGL) over sea ice in the Weddell Sea. 
  • Completed all planned survey lines.
  • ATM, snow and Ku-band radars, gravimeter, and DMS were operated on the survey lines.
  • MCoRDS collected high altitude data over the Antarctic Peninsula.
  • Collected additional ATM and DMS high-altitude data on transit lines.
  • Conducted pitch maneuvers for time stamp verification of snow and Ku-band radars.
  • Conducted one ramp pass (1,500 ft AGL) at Punta Arenas airport before landing for ATM, snow and Ku-band radar instrument calibration.
  • Hosted a question and answer session on x-chat during the flight with students and teachers from New Mexico, Kansas, New Hampshire and Punta Arenas. We reached a total of 68 middle and high school students.
  • Satellite Tracks: none
  • Repeat Mission: October 18, 2011

Mission Report (Michael Studinger, Mission Scientist)

Today, the mission "Twisted" was our best choice in the Weddell Sea. We had some sunny parts, but mostly flew below a cloud deck often changing altitude to main visibility down to the surface for the optical instruments. We were able to collect data along the entire survey line without any significant data loss due to clouds.

The known wildlife colonies along the transit route were at safe vertical separation from the flight path of the DC-8.

The low ceiling and rain showers prevented a ramp pass after takeoff, but we were able to fly a 1,500 ft ramp pass in darkness before landing for ATM instrument calibration.

We hosted another question and answer session on x-chat during the flight with students and teachers from New Mexico, Kansas, New Hampshire and Punta Arenas. We reached a total of 68 middle and high school students.
