EMAG2_V3: Earth Magnetic Anomaly Grid (2-arc-minute resolution) has been added to the World Magnetic datasets on the Geosoft Public DAP Server.
EMAG2 V3 includes new ship and airborne data, and excludes the modelled sea-floor spreading anomalies that were used to supplement areas of sparse marine coverage in v2. The impact of excluding the sea-floor anomalies can be seen in this image of the Indian ocean offshore Somalia and Kenya.
