NERC EDS UK Polar Data Centre. https://doi.org/10.5285/367435d1-b2fd-4692-9570-852f9a21ec02 An airborne radar survey was flown during the austral summer of 2015/16 over the Foundation Ice Stream, Bungenstock Ice Rise, and the Filchner ice shelf as part of the 5-year Filchner Ice Shelf System (FISS) project. This project was a NERC-funded (grant reference number: NE/L013770/1) collaborative initiative between the British Antarctic Survey, the National Oceanography Centre, the Met Office Hadley Centre, University College London, the University of Exeter, Oxford University, and the Alfred Wenger Institute 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. The 2015/16 aerogeophysics survey acquired ~7,000 line km of aerogeophysical data with a particular focus on the Foundation Ice Stream. Our Twin Otter aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, and a new ice-sounding radar system (PASIN-2). We present here the processed line aeromagnetic data collected using the Scintrex cs3 caesium magnetometer mounted in the BAS aerogeophysically equipped Twin Otter aircraft. Data are provided as XYZ ASCII line data.

Flights with 2.5 km line spacing. Standard ADMAP2 processing flow, including IGRF and Tip tank corrections. However, due to the opportunistic nature of the survey no compensation calibration for aircraft motion was performed. Base station correction based on local base station filtered with 30 minute filter, after removal of mean base station value across the survey period. Microleveling utilised gridded line data filtered with 10 km Butterworth How Pass, and cosine directional filter (with Azimuth 35, and degree 1.5). Filtered correction was sampled onto lines and low-pass filtered with 4 km Butterworth filter prior to subtraction. asNeeded completed
