-
Name of marine areas, banks, shallows and depths in Norwegian sea areas.
-
The map layer places the names of Barents Sea, Norwegian Sea and North Sea.
-
The map layer shows the thickness of the upper part of the sediment cover, deposited after the end of last ice age, ca 11000 - 12000 years ago.

The national radon susceptibility data set shows areas in Norway that might be more prone to radon (or: have greater radon risk) than others. In areas marked with high susceptibility, it is estimated that at least 20 % of the homes (houses/residences) have radon concentrations above the upper recommended limit of 200 Bq/m3 at ground floor level. The data set is based on indoor measurements of radon (from NRPA database) and knowledge of geological conditions (databases of bedrock and superficial deposits at NGU). In some areas in Norway radon has been measured in many houses, whereas in other areas there are few available measurements. The data set was developed by statistically considering how the proportion of houses that exhibit high radon concentrations may relate to the local geology, and transferring this knowledge to other areas with similar geological conditions.

Dataset gives outlines of probable occurrences of coral reefs on the Norwegian Continental Shelf without specifying confidence classes. Such outlines are particularly useful for comparing coral occurrences and recognition confidence classification with detailed bottom relief and other types of data. This dataset is one of four datasets created by the automatic classification of detailed bathymetry data.
-
Single pockmarks defined using GIS analysis of detailed depth data. The density of pockmarks is particularly high in areas with soft mud bottom.
-
Areas with particularly frequent occurrence of pockmarks. The density of pockmarks is largest in areas with soft mud bottom.

The national groundwater database GRANADA is available as web map service. The service is related to groundwater in Norway, and provides information on wells and springs in soils and rock, probing, groundwater quality and monitoring of groundwater.
