Mission Summary: 

Mission: Northwest Coastal A
Priority: Baseline

This newer mission was created from the 2010-2012 Northwest Coastal suite of missions by sampling individual coast-parallel lines from those flights to form a grid spaced at 30-35 km from the coast to near the 2000-m contour line. This is one of three missions designed in this way, which together form a 10 km grid in the area. The others are Northwest Coastal B and C. We also add two additional bedrock-mapping lines in the Tracy/Heilprin catchment. This flight was assigned a baseline priority for 2016 because it continues an intra-annual time series with the spring and fall 2015 campaigns along these lines.

A strong and consistent bluebird forecast for this baseline mission made for an easy decision this morning. On the first coastal track, numerous calving fronts were observed along with polar bear tracks. Two airmen from the Thule AB finance office joined us on the flight. All instruments performed well, and expected turbulence was mild.
