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.

Trawl catch data from the Nansen Legacy Cruise - Arctic Basin Joint Cruise 2-2 in the Eurasian Basin during August-September 2021. Two pelagic trawls were used resulting in twelve trawl stations in pairs at six locations: eight stations with a Harstad trawl targeting pelagic fish and four stations with a macroplankton trawl for catching larger zooplankton. The Harstad 320 trawl is a standard Norwegian pelagic trawl for pelagic fish (capelin, herring and juveniles) in northern areas and was used with modified rigging. The modified rigging included wire instead of spectra sweeps (both 60 m long), reducing the total buoyancy of the trawl net (from 1047 kg to 50 kg), and applying 150 kg weights in front of each lower wing and a 40 kg weight at the end of the cod-end. The macroplankton 92 m trawl (trawl opening area of ~36 m2) was used with ordinary rigging, except that 40 kg weight was added at the back part of the cod-end. The macroplankton trawl is a non-graded trawl with 8 mm mesh opening (EN ISO 1107:2003) from the front of the trawl to the cod-end. More information about the trawling specifications and operations can be found in {add link when paper is published}. The data set include station information, trawl catch data (wet weight in g nm-1) and individual length measurements.
