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

Flight Report: 11/03/19
OUTLOOK FOR TOMORROW: Some clouds are forecasted to move back into the Rennick glacier area tomorrow, so another Rennick land ice mission is not viable, however there are a few IS-2 and coastal land ice missions that are viable. There are still no areas/options for a sea ice mission for tomorrow.
Mission: Rennick 01   
Priority: High
Today IceBridge successfully completed the high priority land ice mission Rennick 01. This mission is of importance because it overflies three ICESat-2 tracks with low latency, one track with 20 hours of separation between OIB and IS-2. This mission also flies the centerline of Rennick Glacier, the same line that was previously flown by OIB in 2013. Rennick glacier is almost 200 miles long, and is one of the largest in Antarctica. This glacier also flows directly out into the sea ice pack and ocean and is thought to be more sensitive to oceanic forcing than other glaciers and is also retreating. The data collected today, especially the gravity data will be of great use in understanding of the bathymetry of the ocean surface at this glacier’s outlet affects the amount and how it retreats.
Just as forecasted, and confirmed with satellite imagery this morning, OIB was met with clear skies and light winds in the area of Rennick Glacier. There were some clouds located a bit off shore, however they were not forecasted to move towards the continent, and this was also confirmed during the mission. Conditions throughout the mission were ideal, with clear skies and no turbulence.
All instruments performed well today with 100% data collection. However, on the transit back to Hobart a few problems were noted with the gravimeter and the impact is unknown as of this email. The gravity crew in the field are currently working on the issue, and we hope it’s not ‘mucked up’ (Aussie slang for ‘broken’). Possible missions for tomorrow are not gravity-centric missions.
ICESat-2 RGT latencies (+/- indicates OIB surveyed after/before ICESat-2):
