Mission Location: 
Antarctica
Mission Summary: 

This mission roughly follows the southern leg of the baseline priority Seelye Loop mission (though about 300 km south of the nominal line), a mission flown almost every year of Operation IceBridge. It targets gradients in sea ice freeboard and thickness along the “gate” connecting the tip of the Antarctic Peninsula with Cape Norvegia – although we cannot reach all the way to Cape Norvegia in 2017 due to range constraints of the P-3. The mission was modified to coincide with an ascending TanDEM-X spacecraft ground track, in cooperation with Dr. Son Nghiem’s OTASC experiment as part of a joint collaboration between NASA and DLR.
 
This was a difficult call as only the western portion of the Weddell Sea was clear within the range limit of the P-3. Though we expected clouds on the southeastern portion of the line, model profiles from GFS indicated we may have been able to get under clouds to get data. Some clouds were present about 1/3 of the way through the line and we changed altitude intermittently to avoid icing conditions and maintain visibility while collecting data during clearer sections. About 2/3 of the way through the line we were forced to climb in altitude to stay above the cloud deck, though DMS was able to see down to the surface at some points we were not able to go back down due to fuel considerations.
 
ATM and DMS ran well during the flight, though both were impacted by clouds and altitude changes but otherwise performed well during the clear sections. The magnetometer was a bit noisy during the first portion of the flight as it was positioned more optimally for northern hemisphere flights, it will be adjusted to eliminate the issue for subsequent flights. The gravimeter experienced a data gap due to the use of a remote ground station (the nominal ground station being tied up in cargo). The snow radar was also experiencing low SNR due to an unknown source of noise, it will be investigated for future flights.
