Gravity anomalies have been recovered in the North Atlantic and the Indian Ocean regions. Comparisons of 63 2° × 2° mean free air gravity anomalies recovered in the North Atlantic area and 24 5° × 5° mean free air gravity anomalies in the Indian Ocean area with surface gravimetric measurements have shown agreement to ±8 mGal for both solutions. Geoids derived from the altimeter solutions are consistent with altimetric sea surface height data to within the precision of the data, about ±2 m.
