Mission Location: 
Antarctic Fall 2019: Hobart, Australia
Mission Summary: 

Flight Report: 11/04/19
OUTLOOK FOR TOMORROW: Weather again looks clear in the Cook-Ninnis area of East Antarctica where we have a bunch high priority science mission still needed to complete. A sea ice racetrack mission might be possible this weekend, weather permitting of course!
Mission: Matusevich-Cook IS-2         
Priority: High
The high priority land ice mission Matusevich-Cook IS-2 was flown by IceBridge today, marking the 9th mission of the campaign thus far in 12 possible fly days. Again, like the forecasts and satellite imagery implied, light katabatic flow off the ice sheet in Victoria Land and eastern Wilkes Land caused clear conditions in our survey area. There were some widespread low clouds offshore. Because the katabatic flow off the ice sheet was light no turbulence was experienced during the flight.
The mission today was of importance because it is an area where accumulation has discrepancies between both global reanalyses and regional climate models, like MERRA-2 and RACMO. The survey was situated over flow lines on either side of the Matusevich glacier on areas of the ice that are very slow moving so we can get the snow stratigraphy there from our snow radar. This data can then be used to assess the accuracy of these models. This mission also contains IS-2 tracks, one with a latency of 14 hours!
The gravity team was able to fix the issue with the gravimeter last night, and an operator flew on today’s flight to monitor how it was functioning. Luckily this was not a gravity centric mission so we were not risking collecting data if the instrument had issues. No issues were reported with the gravimeter during today’s flight, and we are glad that it’s not ‘cactus’ (Aussie slang for ‘broken’). All instruments performed well with 100% data collection, except for a 20 minute loss of data midway through the southbound IS-2 line due to a software crash.
Ramp pass was conducted at 1200 feet today post mission.
ICESat-2 RGT latencies (+/- indicates OIB surveyed after/before ICESat-2):
0573 (+ 14 hours)
0832 (- 16 days)
