  • The dataset contains high resolution seismic reflection profiles from the inner part of Kongsfjorden, printed on paper, with selected profiles photocopied. The profiles were taken in summer 1974 during an investigation into glacial processes and the glacial history of Svalbard by G.S.Boulton. There was no attempt to systematically cover the whole of Kongsfjorden but to establish some profiles in what were judged to be critical or representative locations. It was hoped that the profiling would provide a seismic stratigraphy.

  • NO<br> Datasettet viser strandtyper over hele Svalbard. Tre ulike attributter er lagt inn på en kystlinje fra kart i 1:250.000: Kystgeomorfologi (landform) (FORM), kornstørrelse for strandmaterialet (MATR) og spesielle strandformer (SPES). Klassifiseringen er i hovedsak gjort ved hjelp av flyfotostudier. Metodikk og datagrunnlag er beskrevet i den medfølgende kartbeskrivelsen (pdf). For hoveddelen av området er klassifiseringsgrunnlaget bilder fra 1969-1971. Ellers er det brukt bilder fra andre tidspunkter, der de eldste stammer fra 1936 og de nyeste fra 1990. Kystlinjen er oppdatert i 2009. <br><br> EN<br> The dataset shows the coastal geomorphology of Svalbard. The geomorphology is classified by three different attributes on a 1:250000 scale coastline: Coastal geomorphology (landform) (FORM), grain size of the beach material (MATR) and special features (SPES). The classification is mainly based on aerial photography. Methodology and data are described in the accompanying map description (pdf, in Norwegian). For most of the area, the classification is based on aerial images from 1969-1971. Older or newer images have been used for the remaining areas; the oldest from as far back as 1936 and the newest from 1990. The coastline was updated in 2009.

  • This dataset contains benthic foraminifer and diatom data from sediment cores taken in the Arctic Ocean. Diatom and benthic foraminifer species counts were used for sea-surface temperature reconstructions.

  • NGU has developed a database for geological heritage, which contains nationwide data on sites and areas of interesting geology, which may be worthy of preservation. A map application is already developed.

  • Seabed sediments (genesis) describes the geological processes behind deposition of the sediments in the uppermost 1-2 m of the seabed. The map is equivalent to Quaternary maps on land. The dataset series comprise three datasets: Seabed sediments (genesis), overview, Seabed sediments (genesis), regional and Seabed sediments (genesis), detailed. The three individual datasets are digitized in different scales and have different data coverage.

  • Data on various environmental resources have been assessed for vulnerability to acute oil pollution and given a priority 1 to 3, 3 being the most vulnerable. Resources included are shoreline cultural heritage sites, walrus and harbour seal haul-out sites, seabird colonies, anadromous Arctic charr river outlets, and shoreline substrate. The dataset is meant to help prioritize clean-up efforts in the immediate phase after a spill has occurred.
