Mission Summary: 

Mission: Zigzag East
Priority: High
This mission is a repeat or near-repeat of an OIB flight flown in prior years. It is intended to sample the thick multi-year ice near the Greenland coast as well as the gradient to thinner ice closer to the pole. The eastern- and westernmost gradient lines are CryoSat-2 ground tracks. In addition to Level 1 Requirements SI1 and SI2, the mission addresses sea ice level 1 baseline requirement SI3b by sampling thick multi-year ice near the northern coast of Greenland and the poleward gradient towards thinner ice.
A nearly clear satellite image of this region made for an easier decision today. We selected two low-latency CryoSat-2 underpasses and surveyed those. We had great views of the northern margin of the Greenland Ice Sheet on our transit to the survey line. We encountered intermittent clouds and fog at the beginning of the survey line, which soon cleared, and which we encountered again on the southwestern end of the main survey. The survey lines otherwise proceeded uneventfully over what appeared to be mostly first-year ice. We returned via Nares Strait and passed over Inglefield Land to get back to Thule. Snow radar briefly had a loose connection, and Headwall continued to experience shutdown issues but good progress was made, but otherwise all instruments performed well. ATM reported 95% altimetry coverage, limited only by brief cloudy periods. We flew a ramp pass at 2,000 ft AGL.
