Aeromagnetic data provides important constraints on the sub-surface geology of a region. This dataset contains aeromagnetic line data collected by the British Antarctic Survey during the second aerogeophysical survey carried out as part of the International Thwaites Glacier Collaboration (ITGC). Data were collected using a caesium magnetometer system, and have been corrected to total field values following the approach laid out by the SCAR ADMAP working group (https://www.scar.org/science/admap/about/). In total 8688 km of data is presented, of this ~6052 km was collected in the main survey area, while other data was collected on input transit flights. The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL. Data are available as an ASCII table (.csv). The Thwaites 2019/20 aerogeophysical survey was carried out as part of the BAS National Capability contribution to the NERC/NSF International Thwaites Glacier Collaboration (ITGC) program. Data processing was supported by the BAS Geology and Geophysics team.

This data set contains aeromagnetic data collected opportunistically during an airborne radar survey of the Brunt Ice Shelf as part of the NERC/BAS Life Time of Halley project. The survey was flown draped with an average height above the ice surface of 420m, and includes 4716 km of new data. The aircraft used was the BAS aerogeophysically equipped twin otter VP-FBL. Data are available include all data streams from raw to fully processed, following the ADMAP 2 naming convention, and are provided in both Geosoft database (.gdb) and ASCII file formats (.xyz). Base station data is also provided.

Data were collected using a caesium magnetometer system, and have been corrected to total field values following the approach laid out by the SCAR ADMAP working group https://www.scar.org/science/admap/about/. Across flow flights were generally flown at a constant altitude ~450 m above the ice surface, but data was also collected along draped sections flown along the ice flow direction. In total 9872 km of data is presented, of this 6033 km was collected in the main survey area, while other data was collected on input transit flights. The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL. Data are available in ASCII file format (.xyz).
