Mission: 
OIB
Mission Summary: 

This line was designed to survey a set of lines passing over three undersea moorings from the Beaufort Gyre Experiment project and transit as far north into the main pack ice as possible along the 150 degree line of longitude to coordinate with the flight of the SIZRS (Seasonal Ice Zone Reconnaissance) project C-130.
We started out under clear skies from Barrow and obtained some data at high altitude during transit over patchy thin clouds over areas of highly varying ice concentration. Data was collected until the descent to the GAM1 mooring waypoint when clouds became thicker and the laser was not able to penetrate through. We passed over undersea mooring waypoint GAM1 at 20:07Z and NBGOSB at 20:43Z. After the GAM1 waypoint the ATM was not able to range through the clouds, during this time the ATM system malfunctioned and the system was brought back after the NBGOSB waypoint, during this time we descended down to 1100 feet to get under the cloud deck. After waypoint SZR770 the ATM system began to range through to the surface again through a mixture of thin and thick clouds along the line, generally clearing out as we headed south. The Coast Guard C-130 with the SIZRS experiment passed near at 21:33Z, after that we diverted the line towards a large sea ice floe towards the east to get measurements of compact pack ice under clear skies, much good data was collected during this portion of the flight. We continued south along the 150 longitude line past the SZR740 waypoint until 21:59Z as there was still substantially large ice floes encountered and almost no clouds.

Overall, it was a successful first mission with a wide variety of data (pack ice, melt ponds, refrozen melt ponds, snow-covered ice, snow-free ice, and ridges) collected under cloud free conditions in concentrated sections of the pack ice. ATM collected about 1 hour of good data along the flight line.
