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.

This dataset comprises a multidirectional hillshade raster derived from the Greenland Mapping Project (GIMP) Digital Elevation Model. The hillshade was produced to serve as a semi-transparent overlay for cartographic applications, enhancing terrain depth and surface detail while preserving the original colour characteristics of underlying map layers. The multidirectional illumination method reveals terrain variation from multiple light directions, providing improved representation of landforms compared to traditional single-direction hillshading. The dataset is intended for visualisation purposes in web maps and other cartographic products.

The geological map of Greenland at a scale of 1:500 000 is based on 14 digitised map sheets covering the whole of Greenland, with amendments in specific areas (Pedersen et al. 2013, GEUS Bulletin, DOI: 10.34194/geusb.v28.4727). The original digital version of the map was released through the Greenland Portal in 2012. Continued advances in geological knowledge have necessitated successive revisions in order to keep the map up to date. During the most recent update, a number of geographical areas were revised based on new geological data and interpretations, including parts of West Greenland, North Greenland, North-East Greenland, East Greenland and South-East Greenland. The updated map incorporates revised stratigraphic interpretations and improved representation of geological units and structures. The map has undergone extensive quality control, including complete harmonisation of lineaments and structural elements across map-sheet boundaries. The geological legend is dynamic and reflects the content of the current map view. Geological units are supported by descriptive information, and for most map polygons links are provided to a geological unit database containing further descriptions.

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.

Ujarassiorit is Greenland’s national mineral hunt, a public competition open to residents of Greenland. The initiative encourages participants to collect and submit rock samples from anywhere in Greenland to the Ministry of Mineral Resources for geological evaluation. Submitted samples are assessed by geologists, and selected participants may be awarded prizes. The purpose of Ujarassiorit is to increase public awareness of Greenland’s mineral resources and to support mineral exploration by identifying areas of geological interest through public participation. The initiative contributes to the collection of geological information and promotes engagement with geoscience among the population.

The dataset contains polygons representing historical exploration and exploitation licences for mineral resources in Greenland. The data are based on geographic information provided via WFS by the Ministry of Mineral Resources in Greenland and are redistributed without modification of the original boundaries. The dataset provides an overview of former licence areas and their spatial extent.

The North Atlantic current (red arrows) originates in the hot and salty Gulf Stream which flows out of the Mexican gulf and follows the east coast of the USA. When this current leaves the continental shelf and moves across the North Atlantic itâs often called the North Atlantic current. The North Atlantic current provides a significant amount of heat transport to northern Europe. This heat transport is greatest in winter because the current velocity is greater in that part of the year. The North Atlantic current keeps a very constant temperature and salinity throughout the year. It gradually looses heat and salinity as it flows towards the north east and gets mixed with colder and less salty water. At the south western part of the map where the current leaves the American continental shelf the surface temperature is 15-20 oC and the salinity is approximately 36. When it reaches the inlet to the Barents Sea the surface temperature is reduced to 5 oC in the winter and 10 oC in the summer, while the salinity stays at 35 throughout the year.The North Atlantic current continues into the Polar seas through the Fram Strait west of Svalbard and into the Barents Sea (pink arrows). When it reaches these areas its quickly chilled to 2-3 oC and the salinity sinks towards 34.7.The cooling of the North Atlantic current happens when it comes into contact with the colder and less salty Arctic current (blue arrows) that flows south west towards Svalbardâs east coast, south out of the Fram Strait and south out of the Davids Strait between Greenland and Canada. This current has salinity below 34 and the temperature is between -2 oC and +2 oC. In the same way as the North Atlantic current cools on the way north east the Arctic current heats up on its way towards the south west. The Arctic current does however give a significant colder climate around the coast of Greenland and along the Canadian Labrador- and Newfoundland-coasts compared to Europe coasts.Close to the coasts both on the eastern and western side of the North Atlantic there are lighter coastal currents with salinity between 25 and 34 (green arrows). In these areas both the temperature and salinity varies greatly throughout the season. They are warmer then the North Atlantic current during the summer and colder during the winter. In the same way the salinity varies greatly throughout the year because of the varying freshwater runoffs from land.

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.
