Mission: 
OIB
Mission Summary: 

Mission: Southwest Glaciers 01 + parts of Southwest Coastal 

Priority: High + Baseline



This mission incorporates previously-flown lines over Sukkertoppen Ice Cap and over four glaciers near Nuuk, including Kangiata Nunaata Sermia, Tasersuaq, Narsap Sermia, and Akugdlersupasermia. We also refly a series of ICESat lines covering the southernmost lobe of the Greenland Ice Sheet. We return to Kangerlussuaq along a lengthy ICESat track over southern Greenland. For 2018 we modify this flight to include overpasses of three in-situ experiment sites (DYE-2, SITEJ, and KAN-U) at the request of Mike MacFerrin. 



This mission was an easy choice today, given the forecast elsewhere in Greenland. We experienced nearly completely clear skies and relatively light winds. A lowpass approach over Narssarssuaq (one of our emergency alternate airfields) was performed, with laser and radar instruments briefly turned off. Mild turbulence was experienced, as expected, which was a relief given the significant terrain we crossed during the southeastern part of the mission. We then were able to survey the four southernmost grid lines of Southwest Coastal A, which were missed previously due to clouds, as well as some sites requested by Jason Box. We than completed the four flowlines that are normally part of this mission, but not the survey of Sukkertoppen, for which we had run out of time. All instruments performed well overall, and only a few minutes of clouds were encountered. MCoRDS experienced a malfunction early in flight that caused the loss of about a couple of kilometers of data. We flew a ramp pass at 1500 ft.
