The data set consists of digital elevation models (DEM) of subglacial topography, ice thickness, bathymetry and ice surface elevation of Kongsfjorden, northwestern Svalbard, near Ny-Ålesund (78.9 deg N, 12.4 deg E). The DEMs cover five tide-water glaciers with a grid size of 150 m. The data have a total area of ~1100 km^2 and cover the glaciers Blomstrandbreen, Conwaybreen, Kongsbreen, Kronebreen, and Kongsvegen, including the ice fields Holtedahlfonna and Isachsenfonna. A 50 m resolution DEM is also available for Kronebreen. The compiled data set covers one of the most studied regions in Svalbard and can be valuable for studies of glacier dynamics, geology, hydrology and fjord circulation. For further details see Lindbäck et al. (2018, https://doi.org/10.5194/essd-2018-37). If you use the data set in presentations and publications please also refer to the peer-reviewed paper (Lindbäck et al., 2018, https://doi.org/10.5194/essd-2018-37). The data set will be updated when the quality of the data is improved or if new data sets become available.

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.

Laser leveling exercises with rotating laser were carried out during N-ICE 2015. The sea-ice and snow surface elevation were computed with reference to the local sea-surface found by drilling at the corners of the laser leveling field.

Shaded relief map showing relief on the seabed along with depth indication in blue scale. The map gives a visual understanding of terrain and relative depth, but actual depth values are not available on this map. Only certain coastal areas, where there are bathymetry data from detailed mapping, are represented.

Modelled distribution of marine biotopes in Astafjord, Sør-Troms.

The data set is based on grain size distribution and indicates how easy it is to excavate an area and the expected stability of excavated areas.

Anchoring and mooring conditions in some coastal areas with detailed data coverage, as interpreted from bottom type (hard or soft bottom) and depth. It is distinguished between anchoring and mooring conditions. In this context mooring means the possibility for divers to mount bolts into exposed bedrock (to fasten marine installations), usually at depths less than 30m. Anchoring conditions mean the anticipated relative hold of anchors in the substrate.
