Mission: 
OIB
Mission Summary: 

OIB began the second phase of its summer deployment with the LaRC HU-25A Falcon, based out of Kangerlussuaq, Greenland. With ATM, CAMBOT and FLIR onboard, we’ll be re-surveying portions of the Greenland Ice Sheet that were surveyed this past spring and also surveying a few baseline missions that we weren’t able to survey with the NOAA P-3. Up to 16 flights are planned at a nominal altitude of 28,000', with the possibility of two flights per day under optimal conditions.

Today, we flew Falcon NW Coastal B, which surveys two parallel fluxgates along the northwest coast, inland of NW Coastal A. Cloud cover cross Greenland’s mid-section limited our options. A front in west central Greenland is forecast to dissipate and open up more options for this coming week.

Heading north, cloud cover at the southern end of the transect limited data collection until near Risk Isbræ, but otherwise data collection with ATM T5 was as expected. Numerous supraglacial lakes were observed, but nearly all were in the process of freezing over. There was little sign of active surface melting, suggesting a good match between the campaign timing and overall objective (surface elevation repeats at the conclusion of the melt season).
