Included in the systematic mapping programme of the Hidrographic and Oceanographic Research Plan for the Spanish Exclusive Economic Zone (EEZ), gravity surveys have been carried up in Galicia margin. Using gravity data collected during the cruise carried out in 2001 aboard Hesperides Research Vessel, we have made the Free Air anomaly and Bouguer anomaly maps for this area. Sea bottom terrain correction has been calculated for all readings, -45.60 as maximum value and 36.86 mGal as medium value have been obtained. Typical oceanic Bouguer anomaly values, between 70 and 320 mGal, can be observed in the map, being located the highest values in the southwestern area.
