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.
This data set, as part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, combines interferometric phases from multiple satellite interferometric synthetic-aperture radar systems to derive the first comprehensive phase-based map of Antarctic ice velocity. The precision in ice speed and flow direction over 80% of Antarctica is better than prior mappings based on feature and speckle tracking by a factor of 10. Phase-derived velocity mostly covers the years between 2007 and 2018, while tracking-derived velocity (for regions along the coasts) is mostly found in the years from 2013 to 2017. Additional data acquired between 1996 and 2018 were used as needed to maximize coverage.
This data set is part of the WAISCORES project, an NSF-funded project to understand the influence of the West Antarctic ice sheet on climate and sea level change. WAISCORES researchers acquired and analyzed ice cores from the Siple Dome, in the Siple Coast region, West Antarctica.
Lamorey measured the density of the shallow Siple Dome cores B - I. One-meter sections of the ice core were weighed on a balance beam in the field. The volume was determined by measuring the diameter and length of the core. The data consists of tab-delimited text files of density measurements and a sonic velocity profile, and a .gif format density-versus-depth plot. Data are available via FTP.

This data set provides measurements of stable isotopes of water and deuterium excess for the Siple Dome ice cores. The shallow cores from Siple Dome were analyzed for isotopes with sub-annual temporal detail.
This data set is the result of a study of volcanic ash and rock fragment (tephra) layers in exposed blue ice areas on Brimstone Peak (75.888S 158.55E) in East Antarctica. Tephra samples were collected between 15 November 1996 and 15 January 1997.
The Antarctic ice sheets preserve a record of the volcanic ash layers and chemical aerosol signatures of local and distant volcanic eruptions. Correlation of individual tephra layers, or sets of layers, in blue ice areas will allow a better understanding of the geometry of ice flow in these areas. Tephra layers in deep ice cores can also provide unique time-stratigraphic markers in cores that are difficult to date.
Data include the following information for each sample site: a general description, electron microprobe analysis, GPS location, neutron activation analysis, and a visual description of the petrography.Data are provided as Excel 97 data files, JPG map files, and GIF-formatted BSE images.

The WAISCORES project is part of the National Science Foundation Office of Polar Programs' West Antarctic Ice Sheet (WAIS) initiative, which is aimed at understanding the influence of the West Antarctic ice sheet on climate and sea level change. WAISCORES researchers acquired and analyzed ice cores from the Siple Dome, in the Siple Coast region, West Antarctica. These cores allow researchers to distinguish local from regional influences on the climate records recovered from the cores. Drilling for the Siple Dome core began in November 1996 and finished in January 1999. The core site is located between ice streams C and D at approximately 81° 40' S and 148° 49' W. Preliminary studies indicate that the paleoclimate record preserved in the 1003-meter Siple Dome ice core extends back more than 90 thousand years.
The following WAISCORES investigators have made contributions to WAISCORES research. NSIDC archives data for many of these investigators: Mary Albert, Richard Alley, Robin Bell, Michael Bender, Robert Bindscadler, Pierre Biscaye, Donald Blankenship, Ed Brook, Nelia Dunbar, Joan Fitzpatrick, Tony Gow, Gregg Lamorey, Paul Mayewski, Joseph McConnell, Deb Meese, Nadine Nereson, Charlie Raymond, Eric Saltzman, Eric Steig, Christopher Shuman, Ken Taylor, Lonnie Thompson, Edwin Waddington, Martin Wahlen, James White, and Gret Zielinksi.

Brooks measured methane in approximately 196 samples between 55.6 and 738.5 m (0-20 ka) in the Siple Dome ice core, and then extended the Siple Dome methane record at medium resolution down to about 860m, corresponding to an age of about 45 ka. The team compared the results with data from the Greenland Ice Sheet Project 2 (GISP2) and the Greenland Ice Core Project (GRIP).
