Gravity change, geoid change and remaining postglacial uplift of Fennoscandia

The result obtained hitherto on the Fennoscandian land uplift gravity line indicates that the postglacial uplift process might be more complicated than a pure horizontal flow of mantle (‘Bouguer model’). Simple formulae, valid for a more arbitrary model, are developed for the change of the geoid and for the remaining land uplift. Numerical applications yield a geoid change of about 0.4 mm yr^-1 and a remaining land uplift of the order of 50 m, but the latter quantity is very difficult to determine with reasonable accuracy.
