Mission: English Coast 01 (priority: medium)
This is a new flight, primarily designed to map the bathymetry beneath the Stange Ice Shelf, and the western extremity of the George VI Ice Shelf, along a 20 km coast-parallel grid. This grid spacing improves to 10 km with the addition of the companion English Coast 02 mission. This grid connects with the Ferrigno-Alison coast-parallel grid in the west, and overlaps with the George VI grid in the east. We also fly a tie line along ICESat-1 track 0361.
Another straightforward weather decision today, with English Coast 01 being the strongest candidate with clear-sky observations (from the newly available satellite imagery) and forecast. A light off/cross-shore flow forecast held. PIG Arch was tempting, but a large front moving in from the north threatened the northern half of that survey. A higher stratus layer was observed at the southeastern end of today’s survey, as predicted, but did not affect data collection. A cloud layer below our survey altitude at the northern end of the Stange Ice Shelf limited data collection there for ATM/FLIR/CAMBOT/DMS. ATM estimated 94% data coverage. Radar systems and gravimeter all performed well, which will lead to generation of vital new boundary conditions for these ice shelves. Together with the English Coast 02 mission last week, and ongoing collaborations with the British Antarctic Survey, we will have significantly advanced our understanding of this region during 2016 field campaigns.
All instruments performed well.
We conducted a ramp pass at 1200' on departure from PUQ.

|Comments:||Overall the flight went well. DMS backup camera had issues staying online at the start of the flight but after up at altitude for a bit it came on and stayed on for the duration of the flight. Only lost a little bit of data on the last two lines of the mission due to some clouds but it was clear skies for the majority. They say 94% data collected. Media folks got a lot of video. Another successful flight with plenty of smiling folks onboard.|
