| Resumo: | In this paper we address the comparison among grids from different altimetry derived global gravity anomaly datasets with marine gravity anomalies from cruises in the Argentinean continental margin and adjacent oceanic areas in order to determine if there are significant differences among these data sources, particularly in areas near the coast where there are steep horizontal gravity gradients as over the continental slope, and to identify and delimit those areas. We also analyze the information of ship-borne data from different campaigns carried out at different times and organize them in a consistent database, in a compilation process in which improved versions, new corrections have been created. We investigate which satellite altimetry-derived gravity anomaly grid depicts the optimal fit to the marine data compilation in order to find the one to recommend for use in subsequent applications. The results here presented are the first completed series due to the scope of these reached goal. |
