Mission Report (Michael Studinger, Mission Scientist)

The local weather was suitable again today for science flight number five and we went through our prioritized list of mission plans during the early morning weather brief in order to decide which mission with the highest priority has the best chance of successful data collection given the weather situations in the target areas. Even without the government shutdown we knew that sea ice missions would be a challenge because we are simply too late in the season. The delay caused by the government shutdown has made the situation worse. The eastern Ross Sea was clouded in today but two thirds of the sea ice off the coast of Oates Land from the Terra Nova mission plan looked clear. Likewise, the segments from McMurdo along the Transantarctic Mountains looked fairly clear, however, the satellite image showed mostly open water there. The strong southerly winds over the past couple of days have pushed much of the sea ice out of this area. All in all we would have gotten very little data over sea ice if we had flown this mission. In order or maximize data collection we decided to fly the Dome C – Vostok mission today and hope to get some opportunistic sea ice data on the transit home.

We started the flight with the ICESat-2 cal/val site in Barwick Valley in the Transantarctic Mountains. Unfortunately, the ATM T3 laser (narrow swath) failed shortly after takeoff and was declared dead. Luckily, the ATM T4 laser (wide swath) performed very well and recorded almost all of the returns over the cal/val site despite the high flight elevation and dark target site. Matt Linkswiler from ATM processed the data during the flight and it was very comforting to know on the plane that we have collected the necessary data for ICESat-2 cal/val despite the ATM T3 failure.

We turned towards the East Antarctic ice sheet, collecting data over subglacial lakes before we flew over the French-Italian Concordia Station and the drill site of the EPICA Dome C deep ice core. We continued along the ice divide towards subglacial Lake Vostok and turned towards the Russian base Vostok along a flowline that goes over the lake and through the legendary deep ice core 5G. The main goal was to connect the two deep ice cores at Dome C and Vostok with ice penetrating radar data in order to track internal layers (or isochrones) in the ice from one core site to another.

We continued our flight towards the Transantarctic Mountains connecting several ice core sites that have been drilled during the ITASE traverse. We also completed the 3rd out of three ICESat-2 cal/val tracks over the Transantarctic Mountains. Before landing we collected data over sea ice and flew over a corner reflector on a CryoSat-2 ground track that had been installed on sea ice in McMurdo Sound by colleagues from the New Zealand Antarctic Program a few days ago. We will use the data to validate the snow and Ku-band radar data over sea ice. We also did a pass over the ATM ground calibrations site over Black Island and a ramp pass before landing.

Data collection started 11/26/2013 19:51 UTC and ended at 11/27/2013 03:45 UTC. In total we collected 7.9 hours of science data.
