Mission Summary: 

Flight Report: 10/30/19
OUTLOOK FOR TOMORROW: The forecasts tomorrow show bad weather and clouds in all areas of our East Antarctic science missions, thus we will take a hard down day. Weather looks more promising beginning Friday and we plan to fly then. All the team members have been ‘flat out like a lizard drinking’ (Aussie slang for ‘busy as a bee’) and we are all looking forward to a day off tomorrow.
Mission: Denman 01
Priority: High
Today IceBridge flew about 40% of the high priority land ice mission Denman 01. Besides gathering this valuable data in a region of East Antarctica which has been largely under sampled, this mission was also used as a test of the range of the GV with our lighter load (only 3 non- GV crew OIB onboard) and fuel restraints and forecasted turbulence stress on the GV aircraft. Since the Denman missions are the farthest to the east  of where we can fly, we were able to sample the northernmost line and flux gate of this mission and because of this plan to go back to this area throughout our campaign to survey the remaining lines of the Denman missions when other areas of East Antarctica are socked in.
Despite forecasts of strong winds in the Denman area this morning, turbulence was not as bad as predicted and thus the GV was able to fly the lines without any issues. Just as forecasted by 3 weather models, MODIS imagery and also very low-latency AVHRR imagery, OIB was greeted with clear skies in the Denman area. This AVHRR imagery has been shared with us by the Australian Bureau of Meteorology and from those located at Casey station and has been a great help thus far.
Denman glacier ice shelf is likely exposed to warm ocean waters similar to Totten Glacier and thus is an interesting area that needs to be further surveyed. The radar and gravity data collected today will help constrain the ice shelf thickness and the unknown cavity shape, giving us more information on the ocean-ice shelf interactions here.
