Mission Summary: 

F10 Thwaites Glacier A

 

Accomplishments

 

  • Low-altitude survey (1,500 ft AGL) over Thwaites Glacier.
  • ATM, albedo, KT-19, snow, Ku-band, MCoRDS, gravimeter, and DMS were operated on the survey lines.
  • Collected high altitude data on transit to and from the survey area.
  • Ramp pass at Punta Arenas airport after takeoff at 2,000 ft AGL.
  • Satellite tracks: none.
  • Repeat Mission: portions of 2002, 2009, 2011 and 2012 missions.

 

Instrument Operated Data Volume Instrument Issues/Comments
ATM yes 38 GB A fluid streak outside the T4 window (wide scanner) developed during the flight and reduced 30-40% of the scan on the receive signal, but elevations are expected to be recoverable from the recorded waveforms.
CAMBOT yes 65 GB None.
DMS yes 66 GB None.
Snow Radar yes 407 GB DC-8 radar altimeter interference above 8,500 ft but not on survey lines.
Ku-band Radar yes 407 GB DC-8 radar altimeter interference above 8,500 ft but not on survey lines.
MCoRDS yes 1.1 TB None.
KT-19 yes 10 MB None.
Albedo yes 2.3 GB None.
Albedo camera yes 280 MB None.
Gravimeter yes 2.0 GB None.

 

Mission Report (Michael Studinger, Mission Scientist)

Today's flight is a new mission plan, designed to collect dh/dt measurements over lower Thwaites Glacier. It re-occupies six flight lines first flown in 2011 and 2012 as part of an extensive grid, as well as two crossing lines last flown in 2009, and first flown in 2002 by ATM and CreSIS as part of the NASA-Chilean project.

The areas with promising forecasts for today were the Slessor Glacier and Thwaites Glacier. Thwaites Glacier had much better conditions and higher priority and we therefore decided to fly this baseline mission today.

The conditions in the survey area were good. ATM got 100% surface returns during the low altitude portion of the survey and collected 30 minutes on the way in and 30 minutes on the way out from high altitude. The clouds on the southern end of the survey area stayed just were the models predicted them to be. LiDAR data collection started 11/03/2014 15:15 UTC and ended at 21:15 UTC. In total we collected 5.0 hours of combined high and low altitude LiDAR data.
