The dataset consists of over 62 000 data points, obtained during hydrographic surveys in fjords and coastal areas of Norway from Barents Sea in north to Oslofjord in south. Data points provide an indication of which type of sediment can be expected on the bottom (for example, whether it is coarse grained or fine grained). The distribution of seabed sediments is closely related to the physical conditions and tells about the submarine landscape, currents, waves and sedimentary processes.
NGU researchers have since summer 2011, presented new data from Finnmark, Troms and Nordland. The surveys, both geophysical, geochemical and geological, continues is in its final stage in 2014. Done processed data will be made public as soon as they are ready. Geophysics is done with the help of measurements from aircraft and helicopters.

The dataset shows the subdivision of the seabed into marine landscapes defined as larger geographical areas with homogenous character. The classification is based on Naturtyper i Norge (NiN). The classification is based on bathymetric data with 50-500 m resolution which means that means that the level of detail varies from one area to another. Suggested scale for usage is 1:100 000 - 1: 4 000 000.

Marine limit (ML) indicates the highest level reached by sea after last glaciation. This will depend on where you are in Norway and varies between 0 and 220 m. ML therefore indicates the highest levels of marine sediments (marine and fjord provisions) that are raised to dry land. Issues involving for example clay and landslides in marine clay can thus be ruled above ML but is relevant in several places below ML. Furthermore, clay can limit the distribution of aquifers (sand/gravel) and groundwater quality may be affected by salt water.

The dataset show a series of landforms on the seabed of norwegian coastal and sea areas. Landforms can be created under influence of ice , created by landslades of sediments, created by seabed currents etc. Knowledge of landforms gives the understanding of the processes in the marine environment, both these that shaped the seabed under and just after the ice age, as well as those currently influencing the seabed today.
The Directorate of Mining with the Commissioner of Mines at Svalbard (DMF) is the owner of the data set. The data display areas covered with mineral permits for the Norwegian state’s minerals, according to the "Lov om erverv og utvinning av mineralressurser (mineralloven)" §7; the Minerals Act. The data set contains areas defining active exploration permits (UND) and extraction permits (UTV). The data set has overlapping surfaces; several mineral rights can be issued for the same geographical area, but then have different priorities. The mineral Exploration or extraction permit with highest priority, i.e. the first applicant for the right, in a given area is determined by the date The Directorate of Mining with the Commissioner of Mines at Svalbard (DMF) received the application. This is recorded in the attribute InnsendtDato. For more information contact DMF or visit https://dirmin.no/bergrettigheter

Possibility of marine clay is based on Quaternary (superficial deposit) maps in different scales and data set for marine limit. Superficial deposit surface types below marine limit are classified according to the possibility of finding marine clay and can be roughly divided into six classes. The map service 'Possibility of marine clay' ('Mulighet for marin leire') has been created as a guide to reading a Quaternary geological map. It is important to point out that the map service does not display new information in relation to the Quaternary map. It is also important to check the scale of the Quaternary map, and it should also be taken into account that the estimated marine limit may be associated with some uncertainty. For this reason, polygons, which cross or lie near the marine limit, are included in the classification. However, a hatch shows which part of these polygons lies above the marine limit, and which can therefore generally be disregarded with regard to the possibility of marine clay. Exceptions will be areas where other soil types are on top of marine clay, but then the latter will only occur below the marine limit. Data for water-covered areas are not delivered below the marine limit because the surficial deposits have usually not been mapped (even if some polygons for technical reason cross the shoreline). It should be noticed, however, that marine clay deposits are common within water-covered areas below the marine limit including new, loose sediments. See below and use above link 'Display productpage' to read more about the application including uncertainties and use (only in Norwegian).
Can be used for overall screening of large areas for possible occurrence of marine clay. Other types of data may help to verify whether marine clay is present or not, such as ground drilling data.
The map service 'Possibility of marine clay' ('Mulighet for marin leire') must NOT be used WITHOUT the data set for Marine limit.
NGU is cooperating with the Norwegian Radiation Protection Authority (NRPA)in preparing a map showing where alum shale (black shale) occurs in south-eastern parts of Norway. Municipalities and private landowners can utilize these maps and implement safeguards where recommended. The scale is approximately 1 : 250,000 – i.e. the data are not suitable for use on individual properties or housing estates. The maps may not be used to predict the radon concentrations in individual buildings. The only way to get accurate knowledge about radon in a building, is to conduct a measurement of indoor air. Nevertheless, the alum shale map provides essential information about one of the factors that may cause a particular radon hazard in a given area.

These maps displays areas in central eastern Norway which have moderate and high risk of radon in houses, based on the old limit value of 200 Bq/m3. The data will in 2013 be replaced by nationwide data based on the new measures limit 100 Bq/m3.

The national radon susceptibility dataset 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 dataset is based on indoor measurements of radon and knowledge of geological conditions. In some areas in Norway radon has been measured in many houses, whereas in other areas there are few available measurements. The dataset 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.

Sediment data show mainly the prevalence of soil types covering the bedrock surface. Most of the soils were formed during and after the last ice age. The data shows only the soil that dominates in the upper meters of the terrain surface. Thick and thin layers by other soils may occur further down in the soil profile. The dataset can be used as substrates in the overall land-use and environmental planning, vulnerability analysis, assessment of ground conditions, and groundwater and infiltration potential. Sediment data in scale range of 1: 250,000 is intended to provide a regional overview. In municipal planning for example, there is a need for more detailed soil data and data mapped in scale 1: 50,000 or better may be used.
