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 dataset comprises regional airborne radiometric measurements acquired in Greenland during 1975–1982 as part of systematic geophysical mapping programmes. The measurements were collected using aircraft-mounted gamma spectrometers and record natural gamma radiation from potassium (K), thorium (Th) and uranium (U). The surveys covered large parts of Greenland and were conducted to support regional geological mapping and mineral exploration. The data constitute a historical geophysical reference dataset for analyses of near-surface lithological variations and the distribution of radioactive elements.

The dataset contains aeromagnetic measurements acquired during 1993–1996 in East and North-East Greenland as part of the AWI-AEROMAG project conducted by the Alfred Wegener Institute (AWI). The measurements represent regional airborne magnetometry and include total magnetic field intensity corrected for diurnal variations and the main geomagnetic field. The survey was carried out to support geological mapping and tectonic analysis of eastern Greenland. The dataset constitutes an important geophysical reference for studies of crystalline basement rocks, sedimentary basins and structural features in the region.

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 comprises a geological structural map of the Danish Basin at a scale of 1:500,000 showing the structure of the chalk surface (Top Chalk). The map was published in 1991 as part of the DGU Map Series no. 7 and is based on regional geological interpretation of borehole data and seismic data. The data basis includes deep onshore boreholes, seismic profiles from hydrocarbon exploration, and seismic surveys from the inner Danish waters. The map covers Denmark and adjacent marine areas and was produced to support regional geological understanding of the structure of the chalk surface in the Danish Basin.

This repository contains maps of the thickness of late glacial and Holocene deposits in the Danish sea area, prepared as a basis for planning offshore wind. These are unconsolidated sediments that have not been overrun by the ice sheets of the ice ages, and therefore may have low geotechnical strength parameters. This is a large-scale and very general mapping, and no detailed interpretation of the distribution of sand and clay/mud/silt, respectively, has been made. In relation to the foundations of offshore wind turbines, sandy deposits will typically not pose a challenge, while soft deposits of clay, mud and silt in large thicknesses are assumed to pose foundation challenges. In addition to separate maps of the thickness of late glacial and Holocene deposits, a map of the total thickness of these two units has also been prepared, which thus constitutes a map of the total thickness of potentially soft sediments. Finally, the thickness of potentially soft sediments is used to divide the Danish sea area into categories in relation to the probability of larger thicknesses of soft sediments that could give rise to foundation challenges. Other maps are the thickness of potentially soft glacial lake sediments in the North Sea, the depth to the Pre-Quaternary surface in the waters around Bornholm, as well as the depth to the base of the Holocene deposits and the depth to the base of the late glacial deposits/top of the glacial deposits in the Danish sea area. As a supplement to the maps, a number of themes show where the late glacial and Holocene deposits are primarily expected to consist of sandy sediments. In addition, a number of themes show the Danish exclusive economic zone (EEZ), the location of conceptual geological models that can be seen in the overall report, all interpreted seismic lines, areas with near-surface gas in the sediments, interpreted distribution of the Palaeo-Elbe Valley in the North Sea, distribution of the Weichsel ice and ice-affected sediments in the North Sea, buried valleys (Prins & Andresen 2019; van der Vegt et al. 2012; Ottesen et al. 2020; Kirkham et al. 2024; Sandersen & Jørgensen 2016), structural elements (Al Hseinat & Hübscher 2017; Jensen et al. 2002), ice margin lines (Lange 1984; Kjær et al. 2003; Pedersen 2005; Phillips et al. 2018, 2022; Kirkham et al. 2024; Szuman et al. 2024; Pedersen & Boldreel 2017). The data basis for the work has primarily been new and existing near-surface seismic data and vibrocore drilling. The mapping was carried out for the Danish Energy Agency by GEUS, and is intended to support the development of offshore wind. The results, together with a sensitivity mapping of natural and environmental parameters, initiated by the Danish Energy Agency, are to be included in an overall assessment of suitable areas for offshore wind in Denmark.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Base Cretaceous’ and the Cromer Knoll Group. The map was published in 1995 as part of the DGU Map Series no. 49 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.

EOxCloudless is a global satellite imagery dataset consisting of near-cloudless mosaics derived from Copernicus Sentinel-2 multispectral satellite data. The dataset is produced by EOX IT Services GmbH and is designed to provide consistent, high-resolution surface imagery for mapping, analysis, and visualization purposes. The mosaics are generated by combining a large number of Sentinel-2 Level-1C observations acquired over defined time periods. Advanced pixel selection algorithms and thematic masks (including clouds, cloud shadows, and water) are applied to reduce cloud contamination. For each pixel location, the most representative observation is selected based on statistical criteria and temporal analysis, resulting in near-cloudless composite images. The dataset provides global land coverage and is typically delivered at a spatial resolution of 10 metres for the utilised spectral bands (blue, green, red, and near-infrared). EOxCloudless is suitable for use as a basemap as well as for environmental monitoring, land analysis, spatial planning, and other geoscientific applications.

The dataset consists of a series of ASTER band ratios combined into colour composite images designed to highlight mineralogical distributions and lithological variability in Northeast Greenland. The ASTER scenes were preprocessed with atmospheric, radiometric and topographic corrections, including radiative transfer modelling using ATCOR-3 in rugged terrain mode. A surface elevation model was applied to adjust illumination effects. Non-outcrop pixels were masked prior to generating the final mosaic. Calibrated radiance data were converted to apparent surface reflectance; however, further calibration against ground-based reflectance measurements was not feasible. The dataset represents a derived remote sensing product and not primary satellite data.

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.
