Mission: 
OIB
Mission Summary: 
Mission: Blackwall-Recovery IS-2
Priority: High
 
This new flight is designed to survey the channel of Blackwell Glacier and portions of lower Recovery Glacier along ICESat-2 ground tracks. For these tracks, we specifically target the strong beam of the beam pairs, which in the case of this flight are all center beam pairs.
 
A similar set of meteorological conditions and forecast as yesterday favored a similar mission again today. While conditions improved somewhat in the Stancomb-Willis region, winds abated in the Slessor region and skies were yet clearer there, so we selected the highest priority mission available there. The Weddell Sea was clearer than yesterday, with extensive sea ice and leads readily visible from high altitude. The Blackwall Ice Stream in particular is underexplored relative to its larger neighbors, but our survey today significantly improved radar coverage in this region, with a large majority of today's survey lines also along ICESat-2 ground tracks, except for the across-flow lines. The ice stream's surface itself is relatively mellow compared to its neighbors, with somewhat fewer and less intense crevasse fields, but we observed a variety of surface erosional patterns. We continue to experiment with optimization of data collection for the Headwall hyperspectral imager, but collected a significant volume of hyperspectral imagery data today. Data collection for all instruments went very well, with no issues, and altimetry collection was 100%.
