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.

Dissolved inorganic nutrients (nitrate, phosphate and silicate) were collected from full water column at a total of 38 stations in the Eastern Weddell Gyre, encompassing the coast of Dronning Maud Land, Kong Haakon VII Hav, and Maud Rise. The sampling took place between 12th of March and 31st March in 2019 onboard RV Kronprins Haakon, with cruise number 2019702. The seawater samples were collected in the water column from a CTD-Rosette system (24-Niskin bottle), and the sample bottles were rinsed three times. The samples were preserved with 250 µL chloroform and stored cold and dark until post-cruise analysis of nitrite, NO2, nitrate, NO3-, phosphate, PO43-, and silicate, Si(OH)4, following standard methods (Grasshoff et al., 2009) at the chemical laboratory at Institute of Marine Research, Bergen, Norway. The chemical laboratory performs regular QUASIMEME intercomparison of nutrients and are accredited according to NS-EN ISO/IEC 17025. Three replicates were analyzed for each sample. The detection limits are 0.06 µmol/L, 0.5 µmol/L, 0.06 µmol/L and 0.7 µmol/L for NO2, NO3, PO43- and Si(OH)4, respectively.
The study was funded by the Research Council of Norway (RCN) project “Southern Ocean phytoplankton community characteristics, primary production, CO2 fluxes and the effects of climate change-SOPHY-CO2” (#288370), within the SANOCEAN Norway-South Africa collaboration project.
This dataset contains biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR) from the Barents Sea and Arctic region. Number of surveys and stations visited in the Barents Sea and Arctic has varied over the last 30 years. One major effort is the annual Ecosystem Survey in the fall, with multiple trawl surveys, net tows and CTD water sampling over the course of a month. Additionally, two transects are visited multiple times each year (Fugløya-Bjørnøya and Vardø-Nord). Water samples are also collected during short-term sampling projects (ships of opportunity) from IMR ships visiting the region. Each CTD cast is sampled for dissolved inorganic nutrients (nitrate, nitrite, phosphate, silicate) and phytoplankton pigments (chlorophyll-a, phaeopigments) at predetermined depths and for later analysis at IMR. On occasion, short-term projects have performed Winkler DO titrations and particulate organic carbon and nitrogen (POC, PN) determinations. This unique data set has seen limited use over the years but is a great contribution towards global ocean research and climate change investigations.
