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 contains geographic polygons representing the areas of Greenland covered in GEUS publications and in the DODEX report database. Each publication is associated with metadata including title, authors, year of publication and reference information as well as a link to the digital publication where publicly available. The dataset includes publication series such as GEUS Bulletin, Geological Survey of Denmark and Greenland Bulletin, Bulletin Grønlands Geologiske Undersøgelse, report series and geological map descriptions. The polygons are based on the geographic extent described in each publication and serve as a spatial index for search and visualisation purposes.

This dataset comprises regional geochemical stream sediment data from West and South Greenland and forms the basis of the Geochemical Atlas of West and South Greenland (Steenfelt, 2001). The Geochemical Atlas of West and South Greenland presents the results of a regional stream sediment geochemical mapping programme conducted between 1979 and 1998. A total of 7,122 stream sediment samples were collected from low-order streams with near-uniform spatial coverage across West and South Greenland. The <0.1 mm grain-size fraction of 500 g samples was analysed for major and trace elements using X-ray fluorescence spectrometry (XRF), instrumental neutron activation analysis (INAA), delayed neutron counting (DNC) and loss on ignition (LOI). After systematic calibration and quality control to eliminate analytical bias between different methods and time periods, a harmonised and internally consistent dataset was established containing up to 43 elements per sample. The atlas provides a regional overview of the geochemical composition of the minerogenic fraction of stream sediments and constitutes a geochemical baseline dataset for geological mapping and mineral exploration in Greenland.

This dataset comprises calibrated geochemical data from stream sediment and soil samples collected in North Greenland between 1978 and 1999, supplemented by extensive reanalyses in 2011. The dataset includes selected elements relevant for the evaluation of zinc mineralisation: CaO, K₂O, Ba, Cu, Sr and Zn. A total of 2,469 stream sediment samples and 204 soil samples were included. The analytical values represent the most reliable results following systematic quality control and calibration procedures designed to eliminate bias between analytical methods and analytical periods, as described in Thrane et al. (2011). All values below detection limit are coded as 0 in the dataset. The dataset supports regional assessment of geochemical patterns and mineral potential in North Greenland.

Uniform vertical aerial photographic coverage of Greenland was achieved between 1978 and 1987 at a scale of 1:150.000 by Mark Hurd Aerial Surveys, Inc., Minneapolis, Minnesota, U.S.A., on behalf of the Danish Geodetic Institute. The photography provided systematic nationwide coverage and formed a fundamental reference dataset for mapping and geodetic purposes. The black-and-white photographs were acquired using a Wild RC-10 camera equipped with a super wide-angle lens (focal length 88 mm). The aircraft used was a Gates Learjet 25C, flying at approximately 14 km altitude to achieve the image scale of 1:150.000. To minimise blind areas caused by steep mountain slopes in combination with the wide-angle lens, photographs were acquired with 80% forward overlap and 40% side overlap. Photo centre coordinates were established through aerotriangulation performed by the Danish Geodata Agency. The dataset has subsequently been used for mapping, aerotriangulation and scanning applications.

The data set shows data on ship traffic in the period 1 July 2016 to 30 June 2017 distributed in a grid of 250 x 250 meters. The data show all ships with class A AIS transponders. The data source is Havbase. The stronger the color the more passes of the route in the period. This provides a good overview of the large traffic flows.
