Abstract
The geoid height in continental domains can be determined by comparing levelling data with GPS positioning. We apply this method along a N-S transect in the Alpes-Maritimes, between the Ligurian basin and the M ercantour range. A modelling of the geoid profile indicates a very thi n continental crust under the Ligurian sea margin and a 35 km deep cru stal root under the southern Alps, shifted to the N-E relative to the Mercantour range.
