Mission: 
OIB
Mission Summary: 

Mission: Holmes-Frost 01
Priority: Medium
 
This mission is designed to survey the lower portions of the Holmes, De Haven and Frost Glaciers, their ice shelves, and the upper portion of Porpoise Bay beyond, all on a 10 km grid. This grid is designed to supplement earlier airborne measurements collected by the ICECAP Project. We also fly a tie line, designed along an ICESat-2 track. This grid is supplemented by the grid flown in the companion Holmes-Frost 02 mission.
 
Light to moderate katabatic flow in the Holmes and Frost catchment areas led to clear skies in this area today. We observed completely clear skies and light winds and little turbulence. Due to fuel concerns, we did not fly the outboard/northerly-most grid line, similar to the compromise for Holmes-Frost 02. All instruments performed well, with 100% successful data collection aside from the skipped last grid line over the course of 2.5 hours of survey time. We performed a ramp pass at 1200 ft AGL on arrival at Hobart.
