To determine the effect of crustal thickness variation on satellite-altitude geopotential anomalies we compared two regions of Europe with vastly different values, CentraVSouthern Finland and the Pannonian Basin. Crustal thickness exceeds 62 km in Finland and is < 26 km in the Pannonian Basin. Heat-flow maps indicate that the thinner and more active crust of the Pannonian Basin has a value nearly three times that of the Finnish Svecofennian Province. Ground based gravity mapping in Hungary shows that the free-air gravity anomalies across the Pannonian Basin are near 0 to +20 mGal with shorter wavelength anomalies from +40 to <+60 mGal and some 0 to >-20 mGal. Larger anomalies are detected in the mountainous areas. The minor value anomalies can indicate the isostatic equilibrium for Hungary (the central part of the Pannonian Basin). Gravity data over Finland are complicated by de-glaciation. CHAMP gravity data (400 km)indicates a west-east positive gradient of >4 mGal across CentraVSouthern Finland and an ovoid positive anomaly (-4 mGal) quasi-coincidental with the magnetic anomaly traversing the Pannonian Basin. CHAMP magnetic data (425 km) reveal elongated semicircular negative anomalies for both regions with South-Central Finland having larger amplitude (<-6 nT) than that over the Pannonian Basin, Hungary (<-5 nT). In both regions subducted oceanic lithosphere has been proposed as the anomalous body.
