Mission Summary: 

OIB completed the baseline priority Thwaites A mission. This is a new mission, designed to collect dh/dt measurements over lower Thwaites Glacier. It re-occupies six flight lines first flown in 2011 and 2012 as part of an extensive grid, as well as two crossing lines last flown in 2009, and first flown in 2002 by ATM and CreSIS as part of the NASA-Chilean project.
The unlucky aspect of the 13th science mission appeared to strike us at the beginning with a late take-off due to troubleshooting of instrument issues, primarily the need to adjust ATM T6 laser power which inadvertently impacted the real time display of the ATM start pulse. DMS also showed a minor malfunction in their Applanix system—our most reliable system of the campaign—which was later found to be benign. Thanks to the quick work of the instrument teams these issues were fixed in time to prevent further problems. Overall, the mission was fully successful with no loss of data along the line due to instrument issues, late take-off time, or weather.
As a matter of long-term concern, the ATM lasers have begun showing degradation of power and we have opted to begin using the narrow scan system and high altitude data collections much more sparingly to preserve the systems for the remainder of the campaign. With this change, we will move towards using the wide scan system as the primary instrument on land ice flights and the narrow scan system as a backup. However, the narrow scan system was turned on shortly after the beginning of the data line on this mission to ensure data integrity while quality checking of the wide-scan system was undertaken in flight. Thankfully, these quality checks observed good data collection.

Comments:Good flight. The aircraft came back in good condition. This was a new mission, designed to collect dh/dt measurements over lower Thwaites Glacier. It reoccupies six flight lines first flown in 2011 and 2012 as part of an extensive grid, as well as two crossing lines last flown in 2009, and first flown in 2002 by ATM and CreSIS as part of the NASA-Chilean project. A ramp overpass calibration was flown at the start of the mission.
