OIB - DC-8 - AFRC 11/03/18 Science Report
Mission: Hamilton Line – Amery Sector
Priority: High
The forecasts last night gave IceBridge hope of completing its 3rd baseline mission in a row, but deteriorating conditions over Pine Island and Thwaites led us back to the far south: Hamilton Line – Amery Sector. Cloudy conditions over the Bellingshausen Sea and Antarctic Peninsula gradually transitioned into clear blue skies as we approached the start of the 1.3-hour long survey at nearly 88°S.
Due to the location of this sector, on the return transit we passed directly over Amundsen-Scott South Pole Station much to the excitement of all on board!! IceBridge was able to capture a clear shot of the entire station with CAMBOT.
Most impressively, the well-orchestrated teamwork displayed by the entire IceBridge team (both in air and on the ground) led to a perfectly on time departure from Ushuaia. This feat is extremely impressive considering it was our first flight attempt at our new destination and that we encountered a few unexpected bumps in the morning.
All instruments reported excellent data collection and quality. The design of the Hamilton Line – Amery Sector covers about one-third of the southernmost extent of the ICESat-2 ground tracks; thus, latency is variable. Our newest guest, ICESat-2 Project Scientist Thorsten Markus, could barely contain his excitement as he experienced first hand the coordination between these two missions.
As of today, IceBridge has surveyed 6,572 nautical miles of ICESat-2 ground tracks. Way to go team!
Media: Romain Potoki and Florent Muller of France2 joined us today, conducting interviews and collecting footage for a feature-length documentary.
Outlook: Tomorrow’s forecast over the IceBridge Amundsen Sea Embayment baseline targets is favorable. Weather in Ushuaia was not an issue today, and we look forward to many more flights over the remaining weeks.
