Mission Summary: 

IceBridge successfully completed the high priority Dotson-Crosson mission. This is a new mission, designed to collect surface dh/dt measurements over the Dotson and Crosson Ice Shelves and over the lower Smith, Kohler and Pope Glaciers. Most lines were previously flown by OIB, and the two primarily cross-flow lines in the western part of the survey were first flown by ATM and CreSIS during the NASA-Chilean 2002 project. We added a new line crossing the northwestern corner of the Crosson Ice Shelf to investigate a possible overdeepened region in the sea floor there, and we also added a central flowline of the Smith Glacier.

ATM suffered a chiller failure before the start of the data line causing the wide-scan system to be inoperable for the flight. The ATM narrow scan instrument operated successfully during flight such that the laser altimetry time series in the region can be maintained.

All other instruments performed well during the flight with no loss of data due to clouds or other instrument issues. Some high altitude ATM and DMS data was also collected over sea ice and land ice during the transits.

Purpose of Flight:Science
Comments:Good flight. The aircraft came back in good condition. A ramp overpass calibration was flown 1500 ft AGL at the start of the mission. This wa a new mission designed to collect surface dh/dt measurements over the Dotson and Crosson Ice Shelves and over the lower Smith, Kohler and Pope Glaciers. Many of the lines had been flown in previous years, but new ones added this year. All the sceince instruments performed well with the exception of ATM laser T6. The chiller failed prior to descent to the target area so no data for this flight. The T5 laser did perform well throughout the mission. Post-flight, the chiller unit was replaced and the lasers in T6 & T5 were swapped to increase maximize probability for a good laser in the higher priority T6 measurement for the next flight. Weather was ideal for all science data lines.
