Mission Summary: 

Mission: Sea Ice - TanDEM-X B (priority: N/A)

This is a coordinated flight with the TanDEM-X spacecraft, and is also similar to the baseline-priority Seelye Loop North flight.  It is intended both to improve spatial coverage of sea ice conditions in the west-central Weddell Sea, and also to gain additional near-synchronous data collection with TanDEM-X in coordination with the OTASC experiment.

A very persistent storm system in the eastern Weddell Sea has frustrated all of our efforts to obtain any sea ice coverage in that area, and it did so again today.  The entire Bellingshausen sector was clouded today as well, and weather over the northern Peninsula and Larsen-C was marginal.  However the western half of the Weddell Sea was almost entirely clear, with only a few cirrus clouds extending into the area from the storm system to the east.  Once again the HRPT satellite imagery provided by our friends at Rothera Station was extremely helpful in confirming this, as was our own MODIS Rapidfire imagery.  Thus well-informed, we launched this mission confident of obtaining science data over most or all of the flight line.  In the event we experienced excellent conditions throughout the flight, with just a few dozen miles of wispy fog near the south end which had little effect on the instruments.

Science instruments mostly performed well, but the snow radar apparently was degraded by incoherent noise for portions of the last 25% of the survey line.  ATM T7 experienced a few unplanned shutdowns, perhaps due to higher-than-normal cabin temperatures, but an insignificant amount of data was lost as a result.  Successful data collection over the entire line was very near 100%.
