Description
Summary:<!--!introduction!--> To facilitate geological studies of the Antarctic region south of 60 o S, Kim et al. (2022) used equivalent point magnetic dipole inversion to produce the comprehensive airborne-to-satellite altitude ADMAP-2s magnetic anomaly model. The ADMAP-2s spherical coordinate anomaly predictions jointly match crustal magnetic anomaly observations from the Swarm satellite mission (Haagmans et al., 2010) and the Antarctic Digital Magnetic Anomaly Project’s (ADMAP) second-generation magnetic anomaly grid (ADMAP-2), which was compiled from over 3.5 million line-km of aeromagnetic and shipborne survey data (Golynsky et al., 2017). The present study investigates the utility of point dipole modeling for differentially reducing the magnetic anomalies to the pole, as well as estimating their first and second order vertical gradient and pseudo gravity anomalies. These anomaly attributes facilitate characterizing the remanent components and correlating the anomalies with possible subsurface sources ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
