Purpose of Flight:Science
Comments:A mostly successful science flight completing the Bellinghausen Sea 2 mission. Low-level clouds resulted in loss of about 1/3rd of the planned science lines for ATM (not untypical to have clouds on part of this mission). All science instruments worked well and the aircraft returned in good condition with no writeups.

Mission Summary: 

Mission: Bellingshausen 2
Priority: Baseline
Today IceBridge completed the baseline mission Bellingshausen 2, which targeted the transition from open water to marginal ice to full ice pack over the Bellingshausen Sea.  The mission was modified to fly from the west to the east to allow time for potential cloudy conditions to dissipate by afternoon closer to the Antarctic Peninsula.  The forecasted clear skies unfortunately only lasted until about midway through the mission, compromising data quality and collection in some instances later in the day.
The ICESat-2 lines were flown directly along a real-time drift corrected ground track at 700’ - 1500’, depending on cloud conditions.  In a few instances during the entire flight, survey altitude was adjusted lower (between in order to move beneath the cloud deck.  The first leg of the mission coincided with a Sentinel 3a overpass with 75 minutes of latency between surveys. Latency is only provided for the contemporaneous ICESat-2 survey.
ICESat-2 ground track and survey latency:
0583, t = 0 at 20:13:24
1345, t > 0
0011, t > 0
Media: Romain Potoki and Florent Muller of France2 joined us for a final flight 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.
