Citation information for individual datasets is often provided in the metadata. However, not all datasets have this information embedded in the discovery metadata. On a general basis a citation of a dataset include the same components as any other citation:
author,
title,
year of publication,
publisher (for data this is often the archive where it is housed),
edition or version,
access information (a URL or persistent identifier, e.g. DOI if provided)
The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
If you use data retrieved through this portal, please acknowledge the SAON Data Portal.
Brief user guide
The Data Access Portal has information in 3 columns. An outline of the content in these columns is provided above. When first entering the search interface, all potential datasets are listed. Datasets are indicated in the map and results tabulation elements which are located in the middle column. The order of results can be modified using the "Sort by" option in the left column. On top of this column is normally relevant guidance information to user presented as collapsible elements.
If the user want to refine the search, this can be done by constraining the bounding box search. This is done in the map - the listing of datasets is automatically updated. Date constraints can be added in the left column. For these to take effect, the user has to push the button marked search. In the left column it is also possible to specific text elements to search for in the datasets. Again pushing the button marked "Search" is necessary for these to take action. Complex search patterns can be constructed using logical operators through the drop down menu above the text field. Text strings that are not quoted are treated as separate words and will match any of the words (i.e. assuming the OR operator). Phrases may be prefixed with '-' to indicate no occurence of the phrase in the results.
Other elements indicated in the left and right columns are facet searches, i.e. these are keywords that are found in the datasets and all datasets that contain these specific keywords in the appropriate metadata elements are listed together. Further refinement can be done using full text, date or bounding box constraints. Individuals, organisations and data centres involved in generating or curating the datasets are listed in the facets in the right column.
The map service shows modeled geological parameters for seabed sediments. The first modeling has dealt with the storage of organic carbon in the North Sea and Skagerrak. The map layers provide an overview of sedimentation rates, concentrations of organic carbon (OK) and accumulation rates of organic carbon in the top ten centimeters of seabed sediments. Each of the three parameters are supplemented with a map layer, which shows the uncertainty in the estimated values.

Abstract:
Marine geological sampling points with associated information on grain size composition of sediments in the upper part (about 0-40cm) of seabed. Samples are obtained with grab or box corer and geological descriptions are based on visual observations of sediments. In cases where the content of the shell exceeds 50%, it is also specified percentage of shell sand and shell sand class.
The dataset consists of a wide variety of landforms created by geological processes, found on the sea bottom. Interpretation is based on bathymetry data and shallow seismic data. As interpretations have been made over the long time and based on data from several mapping projects, the quality and detailedness varies from place to place.

Probable Occurrences of Coral Mounds on The Norwegian Continental Shelf. The map service publishes six map layers, which show likely occurrences of coral reefs on the Norwegian continental shelf. The mapping is based on classification of high-resolution bathymetry data.
The dataset provides an overview of organic carbon concentrations in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were estimated with spatial modelling methods. Uncertainties of the estimates are provided as well.

Abstract:
The dataset provides an overview of modern sedimentary environment and processes on the seabed in terms of deposition, transportation and erosion of sediments.
The data on this theme is based on the content of the grain size map. Detailed mapping in fjords and coastal areas.
The map service includes many layers of various landforms on the seabed. Landforms formed under the influence of ice, by fluid escape from underlying sediments (pockmarks), gravity (slides), currents or waves are interpreted on the basis of detailed bathymetry data and sediment data.

Abstract:
This geologically interpreted data is based on grain size distribution, and indicates how easy it would be to dig into the sea floor, and how stable the dugout depression would be. Sandy sediments, for example, will collapse more quickly after digging a trench than the sediments with finer grain size.
Subsea landscapes of Norwegian ocean areas based on low resolution bathymetry. The map covers areas of 2.4 mill. km2 and is made for presentation in small scale; 1:500 000 for the Barents Sea and the Mid-Norwegian shelf, and 1:1 000 000 for other Norwegian ocean areas. The map gives a good regional picture of terrain variations in areas that have so far been little studied.
This dataset shows the grain size composition of seabed sediments upper part (top 10-15 cm of the seabed). Full coverage grain size data are based on analyzes of seabed samples, analysis and interpretation of digital reflektivitetsdata and interpretation of analog and digital seismic data. Regional scale 1:50 000 - 250000. The dataset covers areas of the Norwegian continental shelf and Skagerrak.
Dataset comprises polygons of 1x1km, each square km bearing information of the number of probable occurrences of coral reefs within it (occurrence density).
The dataset provides an overview of organic carbon accumulation rates in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were calculated from spatially predicted sedimentation rates and organic carbon concentrations. Uncertainties of the estimates are provided as well.
