The core partner data centres that are integrated in NorDataNet are listed in https://www.nordatanet.no/en/node/69. In addition to this NorDataNet harvests information on relevant datasets from a number of other data centres. The data centre responsible for the data presented is usually (but not always) listed in the discovery metadata. In essence NorDataNet is an aggregating service that combines information from a number of existing data centres.
Citation of data and service
If you use data retrieved through this portal, please acknowledge our funding source:
Research Council of Norway, project number 245967/F50, Norwegian Scientific Data Network.
Always remember to cite data when used!
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)
All partner repositories of NorDataNet support Digital Object Identifiers (DOI), but not all datasets are minted. Whether or not minted depends often on source of the data (e.g. operational data are often yet not minted). However, all data centres support persistent identifiers according to local systems. The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
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 identified in the drop down menu with and phrases embedded in quotation marks. Prefixing a phrase with '-' negates the phrase (i.e. should not occur in the results). Searches are case insensitive.
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 combination of search fields (including facets) is based on a logical "AND" combination of the fields, i.e. all conditions are fulfilled for the results provided.

Abstract:
This data set presents various climate data from sites in Barrow and Atquasuk, on the Northern Slope of Alaska. Parameters include thaw depth, air temperature, precipitation, wind speed, light intensity, plant canopy temperature, soil temperature, soil moisture, soil salinity, and relative humidity. Data were collected between June 1995 and August 2001 by various sensors connected to data loggers. Air and soil temperatures are given in degrees Celsius and wind speed is measured in meters per second. All other paramater measurements are detailed in the documentation. The research project was funded by the Arctic System Sciences (ARCSS) Program, grant number OPP 9714103. Data are available via FTP.

Abstract:
This data set provides snow depth measurements in the study area at Toolik Station, Alaska, taken once yearly on May 2nd, for the years 1995 through 2001. Measurements were taken by hand using a steel tile probe and are given in centimeters. The study area is designed in 1.5 meter by 1.5 meter plots, 3 meters apart. 10 measurements were taken within each plot. Data are in table format in text files and are available via FTP.
This work was funded by the National Science Foundation as a part of the Arctic System Science (ARCSS) Program grants: OPP-9321626, OPP-9615845, and OPP-9907185.
This study documents activity patterns and diving behaviour of four bearded seal (Erignathus barbatus)mothers during the lactation period. Depth and velocity were recorded at intervals of 10 s, with a depth resolution of 2 m. The females spent 8 ± 3% (mean ± SD) of their time hauled out on the ice and92 ± 3% in the water. Approximately half of their time was spent diving. During the study 15 077 dives were recorded.The duration of dives was 2.0 ± 2.3 min and diving depth was 17.2 ± 22.5 m (maximum 18.7 min and 288 m,respectively). Haulout periods occurred 3 ± 2 times per day (duration = 44.0 ± 98.1 min). The overall distance swumper day was 48.1 ± 23.2 km. Three dive types were differentiated using a combination of hierarchical and k-meansclustering, one V-shaped grouping and two U-shaped groupings. The most common dive type was U1; these dives werethe deepest and longest type (depth = 28 ± 32 m, duration = 185 ± 146 s), and bottom time occupied a significantfraction of the total dive time (120 ± 120 s). These dives are likely foraging dives. Lactation is energetically demandingfor bearded seals, and females do forage while they have dependent pups.
