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.
This data set provides weekly estimates of sea ice age for the Arctic Ocean derived from remotely sensed sea ice motion and sea ice extent. For more recent data, see the Quicklook Arctic Weekly EASE-Grid Sea Ice Age data product (https://nsidc.org/data/nsidc-0749).
This data set contains soil temperature and soil moisture data from nine sites in China. Temporal coverage varies by station; the earliest record is from June 1998, and the latest is from May 2002. Data from individual stations are available in tab-delimited ASCII text files. An Excel spreadsheet contains the same data compiled together in a single file. NSIDC currently provides these summary data via ftp; the full soil temperature and moisture data set is available from Ron Paetzold, USDA.

The data set presents various metadata/general details on sea ice stations of five Nansen Legacy cruises (JC1-2, Q1, Q2, JC2-2 and JC3) conducted during 2018-2022 with the Norwegian ice-going research vessel Kronprins Haakon (KPH) to the northern Barents Sea, area north of Svalbard and further into the central Arctic, namely Nansen and Amundsen basins. During the on-ice work on these cruises, the information associated with organization of sea ice stations was logged. This dataset includes miscellaneous sea ice stations – specific information and documentation such as ice station reports and on-site notes, station maps and plans, photos, data on sea-ice drift during the on-ice work as well as any other materials found relevant for documenting the event. This information is potentially important as supporting for any further interpretation of results from various multidisciplinary activities conducted during the sea ice station work on these cruises. For more details on the dataset and its structure please see the attached dataset overview file NL_ice_stations_dataset_metadata.pdf
The data set presents physical properties of sea ice from sea ice cores recovered during Nansen Legacy cruises conducted during 2018-2022 to the northern Barents Sea, area north of Svalbard and further into the central Arctic, namely Nansen and Amundsen basins. The dataset includes relevant ice core data from six Nansen Legacy cruises conducted with the Norwegian ice-going research vessel Kronprins Haakon where a comprehensive program on sea ice physics was implemented. More details on the data structure and content are presented in the metadata file NL_sea_ice_cores_physics_dataset_metadata.pdf
