Mission Summary: 

Mission: Helheim-Kangerdlugssuaq (priority: baseline)

This is a repeat mission, and is very similar to missions flown in 2010, 2011, 2012 and 2013. It captures centerline surveys of the two main branches of Helheim, of Kangerdlugssuaq, Fenris and of several branches of Midgard glaciers. We also refly the centerline of the Hutchinson Glacier, and establish a new centerline of a glacier which empties into the fjord of Kangerdlugssuaq Glacier just beyond its terminus.

The high pressure system over the Denmark Strait and southeastern Greenland strengthened further overnight, leaving all of southeastern Greenland from Scoresby Sund to Cape Farewell clear and with light winds today - a perfect day to fly.  We experienced broken stratus clouds across the western portion of the transit lines from Kangerlussuaq, plus a small isolated fog bank that unfortunately obscured the lowest 2000' feet of elevation of Kangerdlugssuaq Glacier, but otherwise the science targets were clear.  The cloudiness over the greater Jakobshavn Glacier basin persisted again today, preventing us from considering a flight in that area.

We observed a large rift at the front of Helheim Glacier today.  It appeared that several hundred linear meters of the entire front of the glacier had recently separated, leaving a wide rift.  See the attached figures for more detail.  Unlike some other recently-observed calving events at Helheim, this one did not result in an overturning of the new iceberg, at least not yet.

All instruments performed normally today, and the ATM experienced no noticeable fouling of its window from hydraulic fluid.  Oddly, however, the DMS operators did note that the aft portion of their frames were "hazy" during at least the latter part of the flight, which would be consistent with hydraulic oil partially obscuring their window.  

Overall, we estimate successful data collection across 95% of the mission.

We conducted a ramp pass over Kangerlussuaq at 2000' AGL.
