Comments:Successful data flight flown in support of Operation IceBridge Thule deployment. Data flight plan was a shortened version of the North Glaciers 01. Flight was shortened to accomodate the normal shorter Friday workday observed by Thule flight operations. No squawks on the aircraft. Next flight tentatively scheduled for Saturday, April 27.

Mission Report (Michael Studinger, Mission Scientist)

A low pressure system centered over the Davis Strait prevented us from flying any of the remaining high priority mission plans today. We had to stay over the northern most part of Greenland to avoid dense cloud cover and decided to fly North Glaciers 01. This mission is designed to resurvey historical ATM longitudinal surveys of several glaciers in northern Greenland, including Steensby, Ryder, and Hagen Glaciers. It also re-occupies ATM lines on the Flade Ice Cap, near Station Nord, and returns to Thule along the British North Greenland Expedition traverse line, which was also flown by ATM in 2002.

On Fridays we have to wait for fuel until the DC-8 rotator has been serviced and we need to be back on the ground one hour earlier than usual at 15:00 LT. This leaves us less than 7 hours for a mission. We had to shorten several of the glacier runs in order to save time. We also skipped waypoint A05 near NEEM and flew high for the transit from A03 to Camp Century to Thule.

Over the Flade Ice Cap we flew over a depression in the ice surface that must have formed over the past several years. Mike Willis had discovered this feature that is almost one hundred meters deep and a few kilometers in size. We slightly offset our planned survey line to collect data over this feature that seems to have similarities with sink holes. A photo and preliminary processed ATM data are attached to this report.

The weather in the survey area was good and we didn't have any issues with clouds as expected.

Low-altitude data collection started 11:11 UTC and ended at 17:20 UTC. 6.1 hours. We also collected an addition 30 minutes of data from high altitude at the end. In total we collected 6.6 hours of science data.
