Mission Report (Michael Studinger, Mission Scientist)

We decided to take advantage of the unusually good conditions over the Thwaites Glacier area and chose Thwaites Glacier Grounding Line #2, which is a high priority mission in a high priority area. The AMPS model and satellite imagery where consistent with the forecast we got at the weather office at Punta Arenas airport and we were confident that this would be a successful day. The conditions where exactly what we had anticipated, with a strong offshore wind (25 – 30 kts) that provided slightly bumpy but cloud-free conditions in the survey area. Today’s mission and last year’s mission are both aligned with the UTIG AGASEA grid, and one of the lines (E05-W05) is co-located with one of the UTIG cross-flow lines to facilitate intercomparison of the OIB and UTIG measurements. Each of these two missions creates a grid with 5 km spacing offset from each other by 2.5 km, so that once both missions are flown the resulting grid will be spaced at 2.5 km. The data intended as input for ice sheet models. All instruments worked well and we collected 4 hours of science data. We also completed a ramp pass at Punta Arenas airport at 1,500 ft AGL after takeoff to ensure good data for DMS and ATM instrument calibration.
