OIB
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-1 tracks, similar to one originally flown by OIB in 2012, but moved upstream by two ICESat-1 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 2018 we return to Thule along a new master grid line, selected to cross some relatively large areas in the bedrock uncertainty map of Greenland. 

With a promising forecast across northern Greenland, we launched this mission. About two thirds of the way across the mission, we raised our AGL to deconflict from AWI’s Polar 6 Basler, which was also operating in the area, and then descended again. We never saw them, but got in contact with them after they landed at Station Nord. No instrument interference was experienced. Some fog materialized upstream of the terminus of Zachariæ Isstrøm as we were completing the transverse grid. All instruments performed well. A single channel in MCoRDS was out of alignment early in the mission but was quickly re-aligned.
