OIB
Mission Summary: 

Mission: Foundation-Academy IS-2 A
Priority: High
 
The forecast last night once again gave IceBridge hope of completing a baseline mission over the Amundsen Sea Embayment, but deteriorating conditions over Pine Island and Thwaites took us east to Foundation-Academy IS-2 A. The team was greeted in the upper Foundation Ice Stream by monstrous crevasses, drifting snow, fields of blue ice, and lots of little peaks perforating the surface.  The conditions were absolutely perfect for IceBridge, and the variety of surface types and slopes should make for excellent validation data for ICESat-2. 
 
Due to the long survey latency, all flights were flown directly along the ground track (not offset) at 1500’. Underlined tracks below indicate that ICESat-2 surveyed prior to IceBridge.  All instruments reported excellent data quality, however, snow radar incurred minor issues on the final track where IceBridge’s survey altitude drifted too close the 1800’ Nyquist zone.
 
ICESat-2 ground track and survey latency:
0126, t = 62 days
0141, t = 63 days
0766, t = 13 days
1315, t = 49 days
 
Media: Romain Potoki and Florent Muller of France2 joined us again today, conducting interviews and collecting footage for a feature-length documentary.
 
Outlook: At the risk of sounding like a broken record, the forecast remains hopeful for two of the Pine Island and Thwaites baseline missions tomorrow. We are additionally watching the Bellingshausen Sea closely as cloudy conditions have largely cleared up for the first time this campaign.  A required down day will be used either tomorrow or Tuesday based on weather forecasts.
