Mission Summary: 
Mission: South Peninsula IS-2
Priority: Baseline
 
This is a repeat flight, designed to assess dh/dt of four glaciers draining the Dyer Plateau. These are the Fleming, Maitland, Lurabee, and Clifford. We also refly a portion of the grounding line along the George VI Ice Shelf, which was last flown in 2011. For 2018 we replace a coast-parallel grid along the western flank of the Dyer Plateau with a similar grid of ICESat-2 ground tracks. We also fly a pair of lines across the northern edge of the George VI ice shelf, primarily to fill a small gap in gravity measurements there. The Fleming Glacier lines in this mission are supplemented by a 10 km grid over Fleming in the Alexander-Fleming flight.
 
Clouds in the Weddell Sea were more extensive than previously forecast for day, favoring a baseline mission on the southern Antarctic Peninsula rather than over the Weddell Sea. Following a delayed take-off, prior to beginning the survey we had to decrease the survey length by an hour to respect crew duty day limits. We opted to remove the highest two ICESat-2 tracks on the southern end of the survey, between Y03000 and Y03002, and between Z12453 and Z12450, so that we could fully preserve the gravity-focused lines over George VI Ice Shelf and the lower-elevation ICESat-2 tracks. Passing over clouds across the northern Peninsula, conditions were ideal for the duration of the mission, with weak winds and bluebird skies. Data collection proceeded very smoothly, although a bothersome IMU failed early in the flight that we are continuing to troubleshoot. We surveyed four flowlines, the Dyer Plateau, the location of the former Wordie Ice Shelf, the outlets east of George VI Ice Shelf along ICESat-2 tracks, and finally the northern end of the ice shelf itself. The crew from CBS News joined us for a second day, conducting additional interviews.
