Abstract

We studied the solid Earth rheology using observations in the North American and Fennoscandian uplift regions, in the form of horizontal and vertical velocities from Global Navigation Satellite System (GNSS) permanent stations. For North America the dataset from Sella and co-workers and for Fennoscandia the BIFROST dataset were used respectively. We performed GIA (Glacial Isostatic Adjustment) modelling with the SELEN program, varying model parameters in order to find the best fit, in the chi-square sense, to the GNSS-derived velocity values. In the GIA modelling, the ice models ICE-5G and KL05 were used. The main results from this research were fitted Earth model parameters for these ice models using data from the North American and Fennoscandian uplift areas. The application of this method to the North American uplift region for these two different ice models is novel.
