Mission Summary: 

Mission: Ferrigno-Alison 01 (priority: baseline)

This flight is designed to collect dh/dt measurements on established OIB flight lines along the Eights Coast near the Ferrigno and Alison ice streams.

The Bellingshausen sector has experienced very poor weather during most of our campaign, but our weather models showed the clouds there clearing somewhat today.  This morning's satellite imagery showed the sea ice mission lines in the Bellingshausen were still mostly covered in thin and relatively low clouds.  They also showed the entire coastal area between Alexander and Thurston Islands covered in a mid-level stratus deck, with the altitude of the clouds discernible by their relatively cold temperature in infrared satellite imagery.  We could not see through this stratus to assess the near-surface conditions.  However, all three weather models we consulted this morning (GFS, ECMWF and WRF) showed the presence of moderately strong katabatic surface winds along this coast.  Katabatics can be depended upon to clear a coastal area because they had to blow a lengthy distance downhill in order to reach the coast, and thus are relatively warm and dry.  By the time we reached the survey area, the surface was indeed very clear, and the mid-level stratus had departed from about 2/3 of the area.  This gave us perfect conditions, and we achieved successful data collection across 100% of the science lines.

Science instruments performed well, with the exception of the snow radar.  The incoherent noise issue that cropped up late during the previous flight corrupted the data from that instrument throughout today's survey.  The CReSIS team believes that a component failure or loose connection is at fault and are currently working to isolate the problem.
