Processed bed elevation picks from airborne radar depth sounding from the FISS 2016 survey covering the Filchner and Halley Ice Shelves (2016/2017)
This dataset contains bed and surface elevation picks derived from airborne radar collected in 2016/17 over the Filchner Ice Shelf and Halley Ice Shelf (West Antarctica) as part of the 5-year Filchner Ice Shelf System (FISS) project funded by NERC (grant reference number: NE/L013770/1) and awarded to the British Antarctic Survey with contribution from the National Oceanography Centre, the Met Office Hadley Centre, University College London, the University of Exeter, Oxford University, and the Alfred Wenger Institute.
The aim of this project was to investigate how the Filchner Ice Shelf might respond to a warmer world, and what the impact of sea-level rise could be by the middle of this century. This collaborative initiative collected ~15,000 line-km of new aerogeophysical data using the 150MHz PASIN radar echo sounding system (Corr et al., 2007) deployed on a British Antarctic Survey (BAS) Twin Otter.
The majority of flights were flown as part of FISS over the Support Force, Recovery, Slessor, and Bailey ice streams. Separate flights over Halley 6 research station and Brunt Ice Shelf were also collected as part of this season. The bed and surface elevation picks for the English Coast part of this season are available at: https://doi.org/10.5285/e07d62bf-d58c-4187-a019-59be998939cc.
