Mean gravity profiles have been obtained from gravity fields constructed using Geosat Geodetic Mission altimeter data for a number of areas over mid-ocean ridges. For spreading rates larger than about 60-65 mm/yr, an axial gravity high is observed with an almost constant amplitude (~12 mgal) that na...
