3D density and susceptibility distribution model derived from 2024 gravity and magnetic surveys of Marguerite Bay, West Antarctica

We present a 3D crustal model of density and susceptibility distribution in Marguerite Bay, west Antarctica. The inversion is based on airborne gravity and magnetic data collected with a Windracers Ultra UAV (2023/2024 Antarctic season) with a line spacing of 2 km and a ground clearness of 500m. The inverted densities and susceptibilities allow us to contain and identify large scale 3D intrusion in Marguerite Bay. We provide a CSV file, which contains the coordinates, the depth and the inverted density and susceptibility distribution.
