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)
The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
If you use data retrieved through this portal, please acknowledge the SAON Data Portal.
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 through the drop down menu above the text field. Text strings that are not quoted are treated as separate words and will match any of the words (i.e. assuming the OR operator). Phrases may be prefixed with '-' to indicate no occurence of the phrase in the results.
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 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 Joint Cruise 2-1 addressed objectives of the work packages Physical drivers (Research Foci 1), Human impact (Research Foci 2) and The living Barents Sea (Research Foci 3) along the Nansen Legacy transect in open water and within the sea ice. The cruise focussed on comparing the state of the physical, chemical and biological conditions in the southern and northern parts of the study area. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-2085836005). The values have not be changed.
This dataset is a collection of the acid-corrected chlorophyll A and phaeopigments measurements taken as part of the Nansen Legacy project (www.arvenetternansen.com), as part of the '2021 Seasonal Study Q1' cruise. The data is from a single depth profile (CTD with Niskin bottles) from station P3 (NLEG07) taken on 2021-03-08T15:36:02.478Z at 33.9986697166667°E and 78.7494766166667°N. Samples were collected from different depths of the water column. Both total Chlorophyll A and collected after passing through a 10µm filter are enclosed if available.
The cruise addressed objectives of the work package Physical drivers (Research Focus 1), focusing on ocean mixing and water transformation process studies in the region east of Svalbard, with particular focus on the Barents Sea Polar Front region. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-1643304797). 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 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 cruise Q1 (Q1: 1st quarter of the year) was part of the seasonal investigation of the northern Barents Sea and adjacent Arctic Basin. The cruise was conducted in March 2021, 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 Foci 1), Human impact (Research Foci 2) and The living Barents Sea (Research Foci 3).

This is the dataset from the publication “Seasonality of marine calcifiers in the northern Barents Sea: Spatiotemporal distribution of planktonic foraminifers and shelled pteropods and their contribution to carbon dynamics” (doi: 10.1016/j.pocean.2023.103121).
Planktonic foraminifers and shelled pteropods from the upper 300 me of the water column were collected using a midi zooplankton multinet (64 µm mesh size) on board of the RV Kronprins Haakon in a latitudinal transect along the northern Barents Sea covering shelf, slope and basin in different seasons from 2019 and 2021. After the recovery, the samples were frozen at -20° C.
