Bouguer and free-air gravity anomalies over Denmark
The dataset presents Bouguer gravity anomalies on land and free-air gravity anomalies in Danish marine areas based on gravity measurements from the national gravity database. The Bouguer anomaly is terrain corrected and is used to investigate variations in subsurface mass distribution, while the free-air anomaly at sea reflects variations in the gravity field without full terrain correction. Gravity anomalies are expressed in milligals (mGal). The dataset was produced by DTU Space and represents a consolidated gravimetric foundation for geological and geophysical analyses in Denmark.

-
The dataset is based on gravity measurements provided by DTU Space from the national gravity database. Bouguer anomalies were calculated for land areas using terrain correction, while free-air anomalies were applied in marine areas. Gravity anomalies are expressed in milligals (mGal). A uniform and strictly defined datum is not available for the entire dataset. The projection is defined in UTM based on the WGS84 ellipsoid, while marine data in Danish waters are predominantly related to the ED50 datum. The dataset was finalised on 12/12/2011.
