OUTLOOK FOR TOMORROW: Today was the last possible science mission for the Arctic summer 2019 campaign. Tomorrow the OIB team will transit from Thule Greenland to Houston Texas and begin de-installation of the instruments.
 
Mission: Helheim-Kangerdlugssuaq
Priority: Medium
 
Again, due to the G-V’s range and speed, IceBridge was able to redesign a science mission that was originally only accessible from Kangerlussuaq to depart from Thule. Today’s final science mission of the summer 2019 Arctic campaign was a medium priority land ice mission focused on multiple southeast glaciers. Specifically, this mission surveys Helhiem, Kangerdlugssuaq, Fenris and several branches of Midgard glaciers. For the mission today we removed all Midgard-area glacier centerlines to allow time for transit from Thule. This mission was last flown in 2018 and not in Spring 2019.
 
 Weather forecasts this morning and satellite imagery again showed that the Arctic Ocean and sea ice missions were not an option due to low cold coverage. Another possible mission for today was Penny Ice Cap, however we would have to wait until 11am local to get satellite imagery for that region, and forecasts disagreed. If the imagery was not clear, then we would not be able to do any other missions today due to the delay. However, southeast Greenland had off shore winds, causing clear skies in the survey areas of our mission. This is exactly what we experienced along with some mild turbulence.
 
We saw a lot of melt conditions at Helhiem Glacier.
 
All instruments performed well today. We lost only ~70 nm of ATM laser data on the northern east-west crossing.
 
ICESat-2 RGT latencies (+/- indicates OIB surveyed after/before ICESat-2):
