Umanaq B

IceBridge successfully completed the medium priority land ice mission Umanaq B today. This mission was the only viable option due to poor weather and low clouds in Northeast Greenland and also in the Arctic Ocean for high-priority sea ice flights. This mission was redesigned to be flown out of Thule (instead of Kanger) for this campaign and had to be slightly adjusted based on the GV range.  The mission is designed to encounter varying degrees of surface melt and refreezing conditions sampling from lower elevations to higher elevations on the ice sheet.

From Matt in the field, “OIB had another smooth and successful flight in Greenland.  We returned to the western coast of Greenland between Thule and Kangerlussuaq to fly the Umanaq B mission.  Only a couple minutes of data was lost by the optical sensors in the northwestern corner of the survey, but otherwise, all instruments operated with no issues.
