Datasets
Dataset is the foundation for our services and applications. If you are to perform a risk and vulnerability analyzes, an impact asessment, work on a municipal plan or load geological data into your map software, then this is the place to search for and download datasets.
If you want to get an overview of all available datasets for download, please use our self service download portal
If you are interested in preprocessed data files, you can subscribe to our ATOM Feed download service for available datasets. Each entry is in its own an Atom feed of individual data files for that dataset.
You can also use client for mass download, by the norwegian mapping authority to automate download of data from NGU as well as other public authorities in Norway.
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 has a separate database for geological literature about Norway. You will find a number of reports and publications on geological topics.

The data set shows anchoring and mooring conditions in selected coastal areas interpreted from depth and bottom type. It is distinguished between anchoring and mooring conditions. In an area of poor anchoring conditions (hard bottom) it may still be possibilities for mooring in bedrock at depths less than 30 m. Suggested scale for usage is 1:10 000 - 1:50 000.

The dataset indicates how easy it would be to dig into the sea floor. The data set covers selected coastal areas and can be used as basis for areal and environmental planning. Suggested scale for usage is 1:10 000 - 1:50 000.

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 data set is an interpretation of the depositional environment at the seabed, and shows which depositional and/or erosional processes that influence the seabed at the present. Suggested scale for usage is 1:100 000 - 1:500 000.
In Norwegian only.
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 seabed sediments (genesis) data comprises an interpretation of the sedimentary processes that have formed the sediments in the upper few meters of the seabed. The interpretation is based composition of sediments, the landforms they create, and where they are located relative to each other and in the landscape. The dataset can be used in the overall land use and environmental planning, vulnerability analysis, habitat mapping, in connection with installations on the seabed etc. Data are suitable for use within the map scale of 1:100 000 - 1:500 000.

The dataset can be used in connection with the overall land use and environmental planning, vulnerability analysis, habitat mapping, in connection with installations on the seabed etc. Data are suitable for a general overview within the map scale of 1:500 000 - 1:1 000 000
The data set shows the sediment grain size composition in the upper part of the seabed (uppermost 0-50 cm of the seabed). Grain size is determined based on analysis and interpretation of seabed samples and video data, water depth, backscatter data and analogue and digital seismic data. Thematic codes are according to the SOSI-standard, versjon 4.0. In the feature class table there is information on the various classes and which term that is used according to grain size composition of the sediment. Several thematic maps build on the Sediments (grain size) maps, e.g. sedimentary environment and bottom currents. Suggested scale for usage is 1:100 000 - 1:500 000.
