  • Terminal moraines (ice marginal deposits) in Norwegian fjords and coastal areas are mapped because of their importance to organisms living on or above the seabed. Terminal moraines are interpreted based on available detailed bathymetry data.

  • Modelled biotopes on the TromsII/NordlandVII area. Analyses of species counts from 222 video transects has allowed to identify ten different biotopes in Troms II/ Nordland VII area. Geological, morphological and oceanographic variables have been used for spatial prediction of the distribution of biotopes across area.

  • Index layer showing the areas where mapping and/or modelling of shell sand is carried out.

  • Modelled biotopes on the Mid-Norwegian Shelf. Seven biotopes have been identified in the area through the use of multivariate statistics, based on bathymetry, geology and dominating fauna.

  • Modelled biotopes in the NordlandVI area. MAREANO video data were to determine the biological communities and this information was put together with bathymetry, terrain and geological data to model the overall distribution of biotopes. Nine biotopes have been identified in the area through the use of multivariate statistics.

  • Distribution of shell sand localities based on modelling. Modelling is based on data collected by NGU, and carried out by NIVA, in the frame of nation program for mapping of biological diversity.

  • Marine areas with shell sand on the bottom. The extent of the areas is based on actual mapping. There are two categories of the shell sand localities: Proven - verified with sampling; Possible - area limits are based on accustic data.

  • Sampling stations where it is registered minimum 50% content of shell sand or shell gravel in the topmost layer of seabed sediments.

  • Marine Nature Types. Results from mapping and modelling of marine habitats, as well as some particular nature types in Norwegian marine areas. The map service shows the distribution of marine Biotopes, Shell sand deposits and Terminal moraines. The biotope maps are made in cooperation by NGU and IMR in frame of the MAREANO programme based on numerous physical, geological and biological parameters. Biotope maps along the coast are products of other projects. Maps of shell sand deposits along the coast are based on mapping (resource maps), and mapping/modelleling (shell sand as a nature type on the seabed). Maps of shell sand as a nature type are made in cooperation between NGU and NIVA in frame of the National Programme for Mapping of Marine Biological Diversity, led by the Norwegian Environment Agency and the Directorate of Fisheries. Also terminal moraines on the seabed, which are considered to constitute a special bottom type for fauna and flora, are mapped in the frame of this programme.

  • Modelled distribution of biotopes for the Troms III and Eggakanten areas to west Finnmark, based on quantitative video observations of oceanic fauna. Geological, morphological and oceanographic variables are used to predict the various biotopes spatial extent.
