Adelie-Clarie Gap 01

OIB completed the land ice “Adelie-Clarie Gap 01”, designed to fill gaps in bedrock topography along the Adelie and Clarie Coasts, on a 10 km grid. The gaps are between previous ICECAP surveys in the region.

According to the NASA mission report; “A calm wind today in Hobart and a promising forecast for the Adelie and Clarie coasts let to this mission selection, our first low-priority mission of this campaign. An impressive headwind (at one point exceeding 80 kt) slowed our arrival slightly. The flight proceeded uneventfully under broken skies with occasional moderate turbulence. We completed the whole mission with 100% data collection and no issues reported. A ramp pass at 1,500 ft AGL was performed upon return to Hobart.

OIB hopes to attempt another mission tomorrow, weather permitting.
