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:
Spectral albedo measurements on sea ice during the third CHINARE expedition with
the Chinese ice breaker MS Xuelong in the Chukchi Sea from 20 to 29 August
2008.Each measurement type (incident, reflected) was made with a different TriOS
Ramses spectroradiometer. These sensors are known to have calibration issues at
the longest and shortest wavelengths for which data are reported; we recommend
using only data from about 350 to 920 nm. No significant quality control has
beendone to these data. Station descriptions: Ia, 20 Aug. 15:00 to 21 Aug.
07:30, Level ice with open melt pond near by, zi: 2.8m, fb: 34 cm, zs: 2-3 to 9
cm. Ib, 21 Aug. 10:30 to 22 Aug. 21:50, Same as Ia, just re-installed after
station fell over. II, 22 Aug. 23:00 to 25 Aug. 02:40, Over refrozen melt pond
and level ice, increasing amount of snow on melt pond with time (snow drift).
III, 25 Aug. 03:50 to 25 Aug. 05:20, Half over snow, half over melt pond,
station fell over after short time, zs: 7 cm. 25 Aug. 05:20 to 26 Aug. 08:40, No
useful data, station fallen over. IV, 26 Aug. 08:40 to 29 Aug. 00:20, Set-up
over open lead, other activities close by, zs: 9 cm, changing cloud cover, new
ice formation in lead (5-7 cm at end).

Abstract:
Data of drop sondes released from an aircraft during cold-air outbreaks over the Fram Strait (4 March 1993). 7 profiles of temperature, humidity and wind are available as a function of distance to the pack ice edge. Details in Lüpkes and Schlünzen 1996, BLM, 79,107-130.

Abstract:
The ARKXXIV/1 cruise of the German icebreaker Polarstern took place from 20 June to 10 July 2009 and was focused on oceanographic investigations in the northern Nordic Sea. The main work sites were Fram Strait between Svalbard and Greenland and in the Greenland Sea. Hydrographic mesurements during the cruise included the standard section in the nothern Fram Strait along 78°50N, which has been occupied regularly since 1997 (27 stations)

Abstract:
This data was collected as part of an international joint effort during IPY to conduct a quasi-synotpic Pan-Arctic survey. During this cruise (ARK-XXIII/3), the work of the previous year (ARK-XXII/2) was extended toward the East-Siberian regions with a CTD transect in the southern parts of the basins from the Canadian Basin to the Nansen-Gakkel Ridge

Abstract:
Sea ice concentration charts based on a manual interpretation of different satellite data. The main satellite sensor used are the SAR sensor (Synthetic Aperture Radar) suplemented by visual and infrared sensors and data from passive microwave sensors. As part of the Copernicus project the sea ice concentration product is gridded to a 1km spatial resoluton and converted to a NetCDF format. The concentration intervals follow the World Meteorological Organization (WMO) total concentration standard. A new product is delivered every weekday around 1500 UTC.

Abstract:
The product is based on a manual interpolation of available insitu observations. This dataset is the predecessor of the gridded ice charts based on satellite data and other sources. This dataset primarily identifies the sea ice edge.
