Popis: The paper presents the comparison and validation of currently available gravity anomalies from the satellite altimetry models with the shipborne and airborne gravity anomalies along the Polish coast and in the Baltic Sea. The mean value of differences between the investigated DTU10 and GMG V24.1 altimetry-derived models is equal to 0.02 mGal. However, significant differences can be seen in the coastal areas. Shipborne and airborne marine gravity datasets, collected over the past 65 years by various institutions, were also compared.
