Mission Location: 
Punta Arenas, Greenland
Mission Summary: 

Mission: Hull-Land 03 (priority: medium)

This is a new mission, one of a suite of five missions designed to map the coastal region encompassing the Hull and Land glaciers and surrounding areas to the west of the Getz Ice Shelf. The twofold purpose is to map the bathymetry and basal topography using the gravimeter and MCoRDS radar, and at the same time to establish surface topography measurements for dh/dt. This particular flight occupies the center of the area of study of the five planned flights. We also overfly LVIS grid lines in the Getz area during transits at high altitude, to obtain high-altitude data on an opportunistic basis.

Weather today was finally, but gradually, improving over our baseline-priority science targets in the vicinity of Pine Island and Thwaites Glaciers.  The weather over the northern Peninsula area today also had improved significantly.  However in our judgment these areas were still not sufficiently clear to risk a mission, so we selected the Ruppert Coast for yet another flight, since it was almost entirely clear.  We expect further clearing over the higher-priority areas late this week.  We encountered perfect weather over the entire Ruppert Coast segment of the missions, significant clouds below us on the westbound Getz (high-altitude) line, and mostly clear skies on the eastbound Getz (high-altitude) line.

Science instruments performed nominally, with the exception of the MCoRDS which apparently lost 18 minutes of data during the Ruppert Coast lines, due to intermittent digital connectivity between the instrument and its data management system.

We conducted a ramp pass at 1200' on departure.

Purpose of Flight:Science
Comments:Good flight. The aircraft came back in good condition. Science objective was a new mission, one of a suite of five missions designed to map the coastal region encompassing the Hull and Land glaciers and surrounding areas to the west of the Getz Ice Shelf. All science instruments had a good flight. MCoRDS had some issues, but got good data most of the flight. MiniRADS "best day ever" and this was their last flight. At start of the flight, an SCCI ramp overpass was flown at 1200 ft AGL.
