The dataset comprises digital element distribution maps based on geochemical analyses of stream sediments collected in West and South Greenland. The maps were produced as part of the geochemical mapping programme underlying the Geochemical Atlas of West and South Greenland. The data represent analyses of various elements in defined grain-size fractions and provide a regional overview of geochemical variations.

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.

The dataset represents a layered 3D geological model of the Danish subsurface based on integration of reflection seismic data, borehole data, wireline logs and lithological information. The model comprises 17 stratigraphic units from the Upper Permian to the Danian and is structured as a layered digital elevation model (LDEM) consisting of 17 grid surfaces with a spatial resolution of 400 x 400 metres. The underlying data have been interpreted from seismic profiles and calibrated against deep wells, enabling the construction of depth and isochore maps for each unit. The dataset covers onshore Denmark and the inner Danish waters and represents the structural and stratigraphic framework of the Danish Basin and the northern part of the North German Basin. The model provides a basis for analysis of the geological evolution and spatial variability of the subsurface.

The dataset contains basic information on the location of onshore and offshore drillholes in Greenland established for scientific research as well as mineral, oil and gas exploration. The dataset functions as a geographic reference layer and, where available, includes links to reports or summary sheets representing the original source of information. The dataset covers drillholes established between 1948 and 2019 and is subject to continuous updates as new information becomes available through scientific publications, press releases and company documentation.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Base Chalk’ and the Chalk Group in terms of two-way travel time, depth, interval velocity and vertical thickness (isochore). The map was published in 1995 as part of the DGU Map Series no. 48 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on regional interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea, and adjacent areas in the Norwegian, British and German sectors are included in order to define regional structural relationships. The map sheet consists of several thematic sub-maps that together describe the structure and stratigraphy of the area.
