The SIOS Data Management Service (SDMS) integrates information from SIOS partner data repositories into a unified virtual data centre, the SIOS Data Access Portal, allowing users to search for and access data regardless of where they are archived. Providers and users have to commit to the SIOS data policy.
The current focus is on dataset discovery through standardised metadata, and retrieval, visualisation & transformation of data. Ultimately, the Data Management Service works towards integration of datasets which requires a high level of interoperability at the data level.
SDMS currently harvests information on SIOS relevant datasets from a number of data centres (see below), some hosted by SIOS partners and some not. Data centres hosted by SIOS partners work to harmonise access to the data allowing integrated visualisation etc for the relevant datasets.
Data centres SDMS is harvesting information from.

Citation of data and service
If you use data retrieved through this portal, please acknowledge our funding source: Research Council of Norway, project number 291644, Svalbard Integrated Arctic Earth Observing System – Knowledge Centre, operational phase.
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)
SIOS recommends all partner data repositories to mint Digital Object Identifiers (DOI) on all datasets. The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
SIOS Core Data
In order to find SIOS Core Data please use the searchable item marked "Collection" on the right hand side of the map and select "SIOSCD". Quick access to SIOS Core Data is provided here.
Nansen Legacy Data
The Nansen Legacy project is using the SIOS Data Management system as the data portal. Quick access to all Nansen Legacy related datasets is available here.
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 from the drop down above the text field and prefixing words with '+' to require their presence and '-' to require their non presence.
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.
Data on ocean turbulent fluxes from Turbulence Instrument Cluster (TIC) deployed below ice floe.
Quality controlled (QC) 3-hourly averaged under-ice turbulence data data, heat flux and friction velocity (u star) with complete metadata (time and position).
Version 2.4 Matlab format has correct Latitudes and Longitudes. Salt fluxes are included, but not quality controlled to the same extent.
Variables: Name Size Units Description friction_vel 1x556 [m/s] Friction velocity u*=((<u’w’>)^2+(<v’w’>)^2)^(1/4) heatflux 1x556 [W/m^2] Heat flux, Hf=rhocp<T’w’> saltflux 1x556 [psu m/s] Salt flux <S’w’> speed 1x556 [cm/s] Horizontal water speed salt 1x556 [PSU] (Practical) Salinity temp 1x556 [oC] Temperature lat 1x556 [o] Decimal degree latitude lon 1x556 [o] Decimal degree longitude time 1x556 [day] MatLab serial date number version Version 2.4 | Algot Peterson | 21-Nov-2019
Salt fluxes are included, but not quality controlled to the same extent, and are thus named saltflux_raw. Variables in the netcdf file (note that the Latitudes and Longitudes are incorrect in the netcdf file):

The cruise aimed to test technology and sensors in protected, calm waters of a Norwegian fjord, to identify an optimum solution and strategy for deployment during Nansen Legacy research cruises in the northern Barents Sea. The cruise was related to objectives of the Nansen Legacy Research Focus 1 Physical drivers and Research Activity C Technology and method development. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-1107806332). The values have not be changed.
