David B
Mission Summary: 

Mission: David B (plus David A mop-up)

Priority: Low (mop-up medium)



This mission is designed to refly ICECAP flightlines over the David Glacier and Drygalski Ice Tongue, which were adversely affected by instrumentation problems in those earlier flights. flowline down the Reeves Glacier. 



We transited the southwestern Ross Sea, crossed perpendicular to the Drygalski Ice Tongue and started up the Reeves Glacier flowline just north of David Glacier. Our pilots spotted blowing snow shortly before moderate turbulence hit us, and we had to clear the line and gain altitude several times before the winds smoothed out higher up past the steep drops into the lower glacier. We lost altimetry over about a third of that flowline due to the altitude gain. We then began and completed all six cross-glacier fluxgates that are part of the David A and B missions, repeatedly grazing David Glacier’s spectacular icefall over undoubtedly dramatic bed topography (aka, David’s Cauldron). We were previously unable to collect David A’s two cross-glacier lines due to clouds. We then opted to descend along David A’s centerline, rather than David B’s, because the former was previously only partially complete (also clouds) and was oriented closer to the centerline of the glacier. Because of the potential for ice fog at Williams Field, we did not opt to refly the Reeves Glacier centerline or the David B centerline. All instruments reported good data collection, except for the portions of Reeves that the laser missed. We operated the radar in narrowband mode (180-210 MHz) all day to ensure thickness measurements in relatively rough terrain.
