Abstract: Abstract Free-air, Bouguer and isostatic gravity anomalies of the Arctic regions, derived from 350,000 irregularly distributed gravity observations, were gridded at a 10 km interval and plotted against rock-equivalent topography. All of these anomalies show various degrees of correlation with topography, depending on the type of anomaly, which tend to mask the geological source of the anomalies. As an aid to gravity interpretation, a new type of gravity anomaly, the enhanced isostatic anomaly (EIA), was developed. The EIA emphasizes anomalies r...
