Mission Report (Michael Studinger, Mission Scientist)

Today's flight is primarily a repeat flight, designed to assess dh/dt of four glaciers draining the Dyer Plateau. These are the Fleming, Maitland, Lurabee, and Clifford glaciers. We also refly a portion of the grounding line along the George VI Ice Shelf, which was last flown in 2011. Finally we establish a new grid uphill from the grounding line on the west side, with grid lines spaced at 20 km. This grid is intended to assess dh/dt in this area, and on its south end it connects with a similarly-designed grid in the English Coast 03 flight. The Fleming Glacier lines in this mission are supplemented by a 10 km grid over Fleming in the Alexander-Fleming flight.

The AMPS and GFS models predicted some patchy low clouds on the east side of the Peninsula, small enough to launch the mission (Fig. 2). The conditions in the survey area were exactly what we had expected.

LiDAR data collection started 11/10/2014 14:22 UTC and ended at 21:04 UTC. In total we collected 6.7 hours of LiDAR data. Conditions in the survey area were nearly perfect. Other than some small patches of low clouds on the east side of the Peninsula ATM and DMS were not impacted by low clouds.
