Zachariae-79N
Mission Summary: 

Mission: Zachariæ-79N
Priority: Baseline
 
This mission reoccupies the centerlines of the Zachariæ Isstrøm and 79N glaciers, plus flies a grid of six ascending ICESat tracks similar to one originally flown by OIB in 2012, but moved upstream by two ICESat ground tracks to account for the breakup of the lower ice shelf. It also overflies a pair of PROMICE sites immediately north of 79N Glacier. We transit to the northeast region along a historical ATM line dating back to 1994. For 2019 we replace the east-west transit lines with new master grid lines, selected to fill gaps in knowledge of bedrock.
 
A clear forecast with moderate winds made for a relatively easy choice to survey northeast Greenland today. A stratus layer west of the ice divide near Camp Century obscured ATM recording for several minutes, but otherwise skies were mostly clear and the grounding line of Zachariæ Isstrøm and ice shelf of 79N were clearly visible. We completed the two flowlines and six across-track ICESat lines, passing over numerous frozen-over periglacial lakes, crevasse fields, capsized icebergs, dramatic cliffs and musk oxen. Brief thin clouds were occasionally encountered at the downstream end of the grid. We then passed over two PROMICE sites on our return to Thule along a new master grid line. After the main survey lines on our return to Thule AB, we surveyed an curious ice dome between Tracy and Heilprin Glaciers that a citizen scientist alerted us to, which was previously intended for the Northeast Grid 05 Prime mission. The Headwall VNIR channels and CAMBOT again experienced brief shutoffs, but otherwise all instruments performed well. We conducted a ramp pass at 1,200 ft AGL.
