Mission Report (Michael Studinger, Mission Scientist)

Today's mission is designed to sample sea ice along the north-south gradient in the southern Beaufort Sea. The leg flown along the 210th meridian facilitates a new collaboration between OIB and the Seasonal Ice Zone Reconnaissance Surveys (SIZRS) program, and it improves the temporal extent of the SIZRS time series into early spring. This is the primary flight in which to incorporate the NRL site overflights near Barrow, with North Beaufort Loop as the backup. In addition to Level-1 Requirements SI1 and SI2, this mission addresses sea ice level 1 projected requirement SIP2d by extending sea ice baseline observations to the southern Beaufort and Chukchi Seas; sea ice baseline level-1 requirement SI9 by coordinating with a field campaign the complements the IceBridge measurements.

The weather forecast, local observation and satellite images looked all very promising for the entire survey area including the ground site near Barrow. We coordinated an overflight with the NRL Twin Otter and CRREL personnel in Barrow. When we descended into the survey area we saw a thick cloud layer and the tower in Barrow reported overcast from 700 - 1200 ft. The cloud layer must have formed quickly after we took off since it was not reported before takeoff (Fig. 2). We did a pass over the 15 km long line at 1,500 ft without getting any LiDAR returns or DMS imagery. The cloud layer was wide spread and thick and too low to underfly. We will try again in a mission next week. As we moved away from the cost on our first outbound line, the cloud layer dissolved 20 nautical miles away from the cost and we surveyed the remainder of the day in perfect conditions as expected.

The snow and Ku-band radars experienced a failure of the NAS recording unit and temporarily switched to a local drive during the transit to the first data line between 18:30 and 19:57 UTC. A few minutes of data were lost at the start of the line in the area with dense cloud cover before the system was rebooted and ready to record data again. 

LiDAR data collection (that recorded surface returns) started 03/15/2014 18:41 UTC and ended at 03/15/2014 23:40 UTC. In total we collected 5.0 hours of science data. The lasers recorded 100% of the surface returns during that time.
