  • We present a 3D crustal model of density and susceptibility distribution in the Wilkes Subglacial Basin and the Transantarctic Mountains (TAM) based on joint inversion of airborne gravity and magnetic data. The applied 'variation of information' technique enforces a coupling between gravity and magnetic sources to give an enhanced inversion result. Our model reveals a large-scale body located in the interior of the Wilkes Subglacial Basin interpreted as a batholithic intrusive structure, as well as a linear dense body at the margin of the Terre Adelie Craton. We provide six netCDF files, which include the input gravity and magnetic data, the inverted gravity and magnetic data, and inverted crustal density and susceptibility distribution. Additionally, a simple jupyter notebook that loads and plots the provided data can be found here: https://doi.org/10.5281/zenodo.8304170 Funding for this research was provided by NERC through a SENSE CDT studentship (NE/T00939X/1)

  • We present a petrophysical catalogue of new density and susceptibility measurements conducted on 320 rock samples from northern Victoria Land, East Antarctica. The rock samples are stored by the Federal Institute for Geosciences and Natural Resources (BGR) in Berlin-Spandau and Hanover, Germany. Funding for this research was provided by NERC through a SENSE CDT studentship (NE/T00939X/1)

  • We present a 3D crustal model of susceptibility distribution in the Messa Range in northern Victoria Land, East Antarctica. The inversion is based on airborne magnetic data with a line spacing of 500m conducted by the Federal Institute for Geosciences and Natural Resources (BGR) in 2010. The inverted susceptibility allows to discriminate the three dominant rock types in the area namely Kirkpatrick Basalt, Ferrar rock and Granit Harbour intrusive. We provide three netCDF files, which include the input magnetic data, the inverted magnetic field, and inverted crustal susceptibility distribution.
