The Greenland Mineral Occurrences Map (GMOM) dataset contains a compilation of geological information on known mineral occurrences in Greenland. For each occurrence, information includes geographic location, size, mineral commodities, mineralisation type, exploration history and a geological description. The data have been collected and compiled from published scientific articles, exploration reports submitted to the authorities in Greenland, and direct geological observations made during fieldwork conducted by geological surveys, academic researchers and mineral exploration companies. The dataset represents a synthesis of existing knowledge on mineral occurrences in Greenland.

The dataset comprises airborne electromagnetic (AEM) measurements acquired in Greenland during 1994–1998 as part of GEUS’ regional geophysical mapping programme. The surveys were conducted using helicopter- and fixed-wing electromagnetic systems and include electromagnetic response measurements as well as magnetic data. The dataset is used for regional mapping of subsurface electrical conductivity and for identifying structural and lithological variations relevant to geological interpretation and mineral exploration.

The dataset represents an index layer showing the geographic extent of archived and unpublished historical geological maps and sections from Greenland. The layer functions as a search and reference tool and does not contain the original map material. The dataset supports identification and access to historical geological archive documents.
-
The dataset contains terrain models of towns and settlements across Greenland delivered by Asiaq and prepared in connection with the Landslide Project 2022. The dataset includes recorded infrastructure such as roads, buildings and administrative boundaries, as well as a comprehensive raster mosaic of elevation models covering all towns and settlements.

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 comprises spatial polygons (Tracts) representing areas in Greenland assessed as geologically permissive for specific mineral deposit types during mineral resource assessment workshops conducted between 2009 and 2014. Assessments were carried out following the principles of the U.S. Geological Survey “three-part quantitative assessment” method (Singer, 1993), except for the 2010 rare earth elements workshop. For each Tract, probabilistic estimates of the number of undiscovered deposits at different confidence levels are provided, along with statistical results from Monte Carlo simulations based on established grade-tonnage models. The assessments do not include economic, technical, environmental or social considerations.

The dataset shows global bathymetry based on The General Bathymetric Chart of the Oceans (GEBCO) 2019. The dataset represents a continuous model of seafloor topography derived from a combination of multibeam, singlebeam and satellite altimetry data. The original global grid has been reprojected to UTM zone 24N to support regional use and integration with other geological and geophysical datasets covering Greenland and the North Atlantic.

Results from laboratory analyses of related to monitoring the quality of water wells and drinking water taps in household. This dataset is part of GEUS' nation-wide database for shallow boreholes, the common public database and is part of Denmarks Environmental Portal. The database is publicly available and is continually updated.

The dataset contains geochemical analytical results for 725 heavy mineral concentrate samples collected by GEUS in Greenland as part of various geological mapping and mineral exploration activities. The samples originate from several campaigns, including a regional campaign conducted between 1982 and 1986 in the Nuuk area, a 1991 campaign in the southern Nuuk region, and samples collected in 2003 in the Qaanaaq region. Additional samples derive from smaller projects and campaigns with limited documentation. Analyses were carried out at different laboratories, including Activation Laboratories and Bondar-Clegg in Canada and Risø National Laboratory in Denmark. The dataset contains raw analytical results, and metadata concerning sampling procedures and analytical quality are not complete for all samples.

This dataset represents a map of ice margin lines and related localities in Scandinavia, illustrating the gradual deglaciation of the Scandinavian Ice Sheet during the last glaciation, the Weichsel Ice Age. The map depicts the ice sheet extent in five main deglaciation phases, as well as the occurrence of recent ice caps, ice-margin localities, De Geer moraines, ice margin lines and hypothetical ice margin lines. The dataset was compiled in 1995 in connection with TemaNord and presents a regional overview of the deglaciation history of Scandinavia. GEUS has provided technical input in producing the ice margin map.
