Geoidal Change and Shore-Level Tilt Along Holocene Estuaries: Sénégal River Area, West Africa

An expedition under "Projet Rheomarge" traced marine deposits along the Senegal estuary. Leveled and dated samples have made it possible to reconstruct portions of paleogeoids of 6500, 5500, and 1800 years before present. The surfaces of these geoids show that the tilt across continental margins predicted by mathematical models is less than 1 meter from the coast to 120 kilometers inland.
