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.

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.

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.
The cruise was a joint campaign of the Nansen Legacy and A-TWAIN/SIOS-InfraNor projects. Within the Nansen Legacy, the cruise contributed primarily to the work package Physical Drivers (Research Foci 1) but also to Research Foci 2 and 3. The main objective of the cruise was the recovery and deployment of the projects moorings in the Barents Sea and north of Svalbard. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-2135074338). The values have not be changed.

The Nansen Legacy cruise Q3 (Q3: 3rd quarter of the year) initiated the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The cruise focused on comparing the state of the physical, chemical and biological conditions along the Nansen Legacy main transect in open waters and within the sea ice, addressing objectives of the work packages Physical drivers (Research Foci 1), Human impact (Research Foci 2) and The living Barents Sea (Research Foci 3). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-1107597377). The values have not be changed.
The Nansen Legacy JC3 cruise (19.02.-11.03.2022) aimed to fill gaps after the earlier NL cruises, in particular during the winter-to-spring transition and in the northern part of the NL transect to the Nansen Basin. Joint physical, chemical, and biological sampling and experiments for new technology addressed aims of RF1, RF2, RF3 and RA-C. Sampling started in the Atlantic domain with a process station at P1. Afterwards, the cruise focused on the northern Barents Sea around and north of Kvit?ya covering process stations at P5, P7 and between Nord Austlandet and Kvit?ya. They lasted from 29 to 68 hours to enable observation of at least one daily cycle in the under-ice water layer. Ice conditions varied but consisted mostly of extensive but thin first-year ice, often as small floes that were frozen together. In the northernmost region, the floes were larger, but the ice remained thin. Despite a fair amount of daylight available, the biological sampling seemed to indicate that the ecosystem was still in winter mode. In addition to the process stations, the northern part of the NL transect was covered from the shelf north of Kvit?ya into the deeper Nansen Basin. This included mainly hydrographic measurements and chemical sampling along the entire transect, biological sampling at P6, and benthic sampling at selected depths from shelf over slope to deep. In the entire region, warm Atlantic water was prominent and close to the surface, potentially explaining the lack of thick sea ice and late ice formation. Before and after the main cruise program, several gliders were recovered. One mooring was pinged but could not be located. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-675177809). The values have not be changed.
The Winter Process Cruise aboard RV Kronprins Haakon conducted dedicated observations on processes that control the position and variability of the Polar Front in the northern Barents Sea and the distribution of Arctic and Atlantic water masses. The cruise addressed objectives of the work packages Physical drivers (Research Focus 1) and Technology and method development (Research Activity C). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-814367946). The values have not be changed.
The Nansen Legacy cruise Q2 (Q2: 2nd quarter of the year) was part of the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The cruise was conducted during the spring period a biologically critical time window when a large part of the annual primary production occurs and focused on comparing the physical, chemical and biological conditions along the Nansen Legacy main transect in open waters and within the sea ice. The cruise addressed objectives of the work packages Physical drivers (Research Focus 1), Human impact (Research Focus 2), The living Barents Sea (Research Focus 3) and Technology and method development (Research Activity C). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-515075317). The values have not be changed.
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.
