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.

Energy class layer produced by EMODnet Seabed Habitats as an input layer (habitat descriptor) for the 2025 EUSeaMap broad-scale habitat model. The extent of the mapped area includes the Baltic Sea, and areas of the North Eastern Atlantic and Arctic extending from the Canary Islands in the south to Norway in the North. The map of energy classes was produced using underlying wave and current data and thresholds derived from statistical analyses or expert judgement on known conditions. This layer was updated in EUSeaMap 2025 using a the wave Kinetic energy layer at the seabed layer for the European Shelf area used in 2023 (linked in the Online Resources). An accompanying confidence layer is available for viewing and download from EMODnet Seabed Habitats - metadata is linked in the 'Composed of' section below. A report on the methods used in the 2025 version of EUSeaMap will be added in due course, but reports on previous versions (v2016, v2019, v2021 and v2023) are available in the lineage.

The topographic map of Greenland at a scale of 1:250.000 is based on data collected from the 1930s through the 1970s and 1980s. These data formed the basis for the production of a series of 1:250.000 scale topographic map sheets, which continue to serve as the primary topographic reference for large parts of Greenland. Mapping of areas prior to 1970 was based on several historical map series, including 18 map sheets at a scale of 1:300.000 covering North Greenland produced by Lauge Koch between 1932 and 1940, 1:250,000 scale mapping of parts of Northeast Greenland conducted by the Geodetic Institute in the 1930s, and complete national coverage at 1:250.000 produced by the American Army Map Service in the 1950s. The digital topographic map of North and Northeast Greenland has been produced by the Geological Survey of Denmark and Greenland (GEUS) since 1977, based on high-precision digital photogrammetry using aerial photographs. The dataset has primarily been used as a topographic reference for geological mapping at scales of 1:100.000 and 1:500.000.

The dataset comprises geochemical analyses of 1,269 soil samples collected in Greenland from 1974 onwards as part of systematic geochemical mapping and mineral exploration programmes. Soil samples were primarily collected in areas lacking developed stream channels where stream sediment sampling was not feasible. The samples represent surface material and have been analysed for major and trace elements using various laboratory methods including X-ray Fluorescence Spectrometry (XRF), Instrumental Neutron Activation Analysis (INA), Inductively Coupled Plasma Emission Spectrometry (ICP), and Atomic Absorption Spectrometry (AAS). The dataset contains the original analytical results as received from the laboratories together with administrative information on sample location and analysed grain-size fraction. The data form part of the analytical basis for the Geochemical Atlas of West and South Greenland.

The dataset shows the depth to the redox interface in metres below ground level across Denmark at a spatial resolution of 100 metres. The redox interface represents the transition between oxidised and reduced sediment layers and is a key hydrogeological parameter influencing processes such as nitrate reduction and groundwater chemistry. The map is based on a statistical model developed from approximately 13.000 observations of colour changes in sediment samples and represents the best estimate of the depth to the redox interface nationwide. The dataset also includes an associated uncertainty estimate describing the variability and robustness of the model results.

The dataset contains geochemical analyses of 49 scree (talus) samples collected in Greenland as part of regional geochemical mapping programmes conducted by the Geological Survey of Greenland (GGU), later GEUS, between 1977 and 1997. Scree samples were collected in areas where neither stream sediment nor soil sampling was feasible. The samples represent near-surface material derived from local bedrock and were analysed for major and trace elements using laboratory methods available at the time of collection. The dataset supplements regional geochemical data from stream sediment and soil samples and forms part of the overall basis for geochemical mapping in Greenland.

The dataset comprises a systematic inventory of onshore petroleum seeps and stains in Greenland. The inventory includes information on approximately 130 localities distributed across Palaeozoic, Mesozoic and Cenozoic sedimentary basins in Greenland. For each locality, coordinates, site descriptions, classification of seep type, geological context, sample numbers and references to reports and publications are recorded. The classification includes oil seeps, gas seeps, mud diapirs and gas-rich springs, oil stains in volcanics, carbonates and sandstones, solid macroscopic bitumen, and fluid inclusions and other evidence of micro-seepage. The dataset synthesises existing knowledge of petroleum systems in Greenland and provides a comprehensive overview of documented natural hydrocarbon occurrences onshore.

The VMap1 collection is a legacy product that is no longer supported. It may not meet current government standards. VMap1 is a vector digital topographic reference product developed by Natural Resources Canada (NRCan) and The Department of National Defence (DND). VMap1 complies with international military specifications vector map, level 1. There are 24 VMap1 libraries covering the Canadian territory. The National Topographic Data Base (NTDB) at scale of 1:250 000 is the main source used to populate the Canadian VMap1 Libraries. Administrative Boundaries from Statistics Canada are used to add international borders, provincial and Indian reserve limits. NRCan paper maps at scale of 1:250 000 and the information in the Canadian Geographical Names Data Base (CGNDB) are used to capture the names. The JOG (Joint Operations Graphic) paper maps were used by DND for the production of libraries 37, 38 and 66. Topographic features mainly from the NTDB have not been updated. VMap1 is published once and no product revision is planned.

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.
