Mission Report (Michael Studinger, Mission Scientist)

Today's flight is a new mission plan that is intended to collect altimetry, radar and gravity data over the lower Institute Ice Stream, entirely along ICESat-1 ground tracks straddling, and upstream of, the grounding line. This area has been traversed by only a single IceBridge line to date, an approximation of the grounding line flown in 2012. Prior geophysical work in the area included a SPRI/NSF/TU-Denmark airborne campaign in the 1970s, an AWI effort in the 1990s, and several ground traverses dating from the late 1950s.

Today we looked at Thwaites Glacier, the English Coast, Evans Ice Stream, and the Institute Ice Stream as candidates based on the weather forecasts. All remaining sea ice mission had unfavorable weather. Unfortunately, we had to drop all high priority land ice targets due to the high risk of loosing data and decided to fly the medium priority Institute 1 mission, which promised to have good conditions. On the way to the survey area we passed over Evans Ice Stream and saw widespread patches of low clouds that would have been impossible to underfly and a safety risk given some of the terrain along this mission.

The conditions over the Institute Ice Stream were good. ATM and DMS only lost 5 minutes of data along the last line due to a small patch of low clouds. A layer of haze was below us for most of the survey, which did not cause any problems.

We observed two almost vertical sidewalls in the bedrock topography on MCorDS over the Hercules Inlet. The steep sidewalls also have a clear expression in the ice surface as seen on DMS (Fig. 2).

LiDAR data collection started 11/15/2014 15:37 UTC and ended at 20:01 UTC. In total we collected 4.4 hours of LiDAR data.
