Nationwide geophysical database for environmental and raw material data, also known as GERDA (GEophysical Relational DAtabase). The database contains various types of geophysics, including geoelectrics, electromagnetics, borehole logs and seismic. All data is freely available for download on the GEUS website. The database is updated continuously.

The National well database (Jupiter) among other things contains water level measurements from Danish wells. The database contains water level measurements from the municipalities, the groundwater-monitoring program, the regions soil pollution investigations and from the establishment of new wells.

The dataset comprises more than 6,400 oblique aerial photographs acquired during the systematic 1:500,000 geological mapping programme in North Greenland carried out by the Geological Survey of Greenland (now GEUS) between 1978 and 1985. The photographs document steep fjord and valley walls and were collected as part of geological field investigations. The images have been digitised and made available through a web-based interface, allowing users to access individual photographs, their geographic locations and associated geological coding linked to the regional geological map. The dataset represents a systematic visual documentation of geological features in North and Northeast Greenland.

The dataset consists of three different datasets with combined place names in various geological maps: Geological map of Greenland 1:2.500.000, Geological maps of Greenland 1:500.000 and Topographic map of Greenland 1:250.000. The dataset has not been updated or maintained since 2014.

The dataset represents a nationwide mapping of buried valleys in Denmark. The map depicts the occurrence, distribution and general geometry of mapped buried valleys in the Danish subsurface. Buried valleys are elongated depressions in the subsurface that are today fully or partly infilled with younger sediments. In Denmark, the majority of mapped buried valleys are interpreted to have formed during repeated glaciations in the Quaternary period. The valleys are typically 0.5–2 km wide and may reach depths of up to approximately 400 m. The dataset is based on interpretation of geophysical data, primarily TEM and SkyTEM surveys, supplemented by seismic data and borehole information. The mapping provides a national overview of buried valleys and forms a key basis for understanding the geological framework of the subsurface.

The MARTA database contains shallow seismic and acoustic data, information and geological samples. MATRA shows the distribution of marine sand and gravel resources and gives access to reports on raw material surveys. MARTA shows the distribution of marine sand and gravel resources and gives access to reports on raw material surveys. Data has primarily been acquired by GEUS and our partners., MARTA is the official Danish marine raw material database for data reported in accordance with the Danish Raw Material Act. MARTA is used by the raw materials industry and authorities and as a planning tool in connection with raw material extraction and marine construction projects including beach nourishment.

The Samba database contains information about geophysical investigations made in the Danish sector, acquired according to the Danish Act on the Use of the Subsoil. The data is acquired in relation to investigation for oil/gas, geothermal energy, the storage of gas or salt. That is: Seismic (2D & 3D) acquisitions, CSEM as well as other magnetic and gravity acquisitions shipborne as well as airborne. The dataset also contains geophysical measurement performed in the deep wells and meta data about the seismic surveys. The data has been submitted by the licensees. The database is updated on an ongoing basis.

This dataset represents the structure and topography of the Top Chalk surface, i.e. the top of the Chalk Group (including Upper Cretaceous to Danian), in the Danish subsurface. The map illustrates regional variations in the depth and structural configuration of the chalk surface from the central North Sea to the eastern Danish areas. It is based on an integrated geological and geophysical interpretation of seismic profiles, well data and earlier mapping. The map provides an essential basis for geological, geophysical and subsurface reservoir analyses.

This dataset depicts the depth to the top of the pre-Zechstein succession in the Danish subsurface. The map represents the structural surface beneath the Zechstein evaporites and provides a regional overview of the geological framework of the subsurface. The dataset is based on interpretation of seismic data, deep boreholes and previous geological mapping and was produced as part of the Geological Survey of Denmark map series no. 45. The map is used as a reference for regional structural geology and subsurface modelling.

The database contains information on deep drilling, carried out under a permit, cf. the Subsoil Act, as well as geophysics (especially seismic), licenses and reports. These are exploration, estimation, delineation and production drillings concerning oil/gas, geothermal energy, gas storage and salt, as well as scientific drillings. The dataset contains technical, administrative and geological information from the drillings and about geophysical measurements in the drillings.
