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
Outline of the data portal search interface.
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.
Differential Mobility Particle Sizer (DMPS) data obtained at the Mt. Zeppelin Observatory, Ny-Alesund. A whole air inlet is used and all aerosols including ones within cloud/fog particles are measured, by evaporating them within the heated inlet tube.
As part of the "KROP - Kongsfjorden Rijpfjorden Observatory Programme" UiT The Arctic University of Norway and The Scottish Association for Marine Science maintain marine observatories (moorings) in two high-Arctic fjords in Svalbard: Kongsfjorden and Rijpfjorden. The observatories consists of an array of CTDs, temperature loggers, ADCPs and a sediment trap, in addition to various other instruments or installations that change from year to year. This dataset contains the CTD, PAR and fluorescence data from Kongsfjorden 2013-2014. Fluorescence data is given as raw voltage only, due to calibration and fouling issues. It is meant as an indication of the timing of the phytoplankton bloom, not as absolute chlorophyll a concentration. No post-recovery processing of light data (to correct for fouling) has been performed. This is the first deployment in which the AURAL acoustic listening buoy got implemented in the design.
In situ measurement of cloud particle number concentration was made using a fog-monitor instrument (DMT FM120) at Mt. Zeppelin, Ny-Alesund, Svalbard Island (78.93N, 11.88E, 478m a.s.l.). This dataset contains ten-minute average of number concentrations for cloud particles with radii between 1.5 and 23.5 um. Each data set contains one-month data. No data is available between August and October 2014.
In situ measurement of cloud particle number size distribution was made using a fog-monitor instrument (DMT FM120) at Mt. Zeppelin, Ny-Alesund, Svalbard Island (78.93N, 11.88E, 478m a.s.l.). This data set contains ten-minute average of number size distribution (dN/dlog_r) of cloud particles with radii between 1.5 and 23.5 um. Each data set contains one-month data. No data is available between August and October 2014.

Measurements of incoming direct, diffuse, and global solar radiation and incoming infrared radiation measured at the Zeppelin Observatory in Ny-Ålesund Research Station, Svalbard.
Data are stored as one-minute averages of 1-Hz measurements. Instruments include 2 Kipp & Zonen CMP22 pyranometers (diffuse and global), 1 Kipp & Zonen CHP1 pyrheliometer (direct), and 1 Eppley PIR pyrgeometer (infrared); they are mounted on a Kipp & Zonen Solys2 sun tracker.
Quality
Data are uploaded to the database daily, without quality control. The two pyranometers and one pyrgeometer are ventilated and heated, and engineers are present once per day Monday to Friday at the station to clean the sensors if necessary. The sun does not rise at the location from late October until mid February, and the top of Zeppelin Mountain can cast a shadow on the instruments in the afternoon.
Time-series data from moorings covering the Svalbard Branch of the Atlantic Water inflow over the upper continental slope north of Svalbard, Sep 2013 to Sep 2015. The data comprise temperature, salinity and other parameters from CTDs, and water currents from ADCPs.
Data are published as individual time-series files from the different instruments. Both raw (RDI .000 format) and processed (netCDF) ADCP data are published.
Quality
Data processed with standard software from the instrument manufacturers plus additional quality controls to remove bad data points. Details of ADCP processing and quality control are described in the documentation PDF.

The A-TWAIN cruise onboard R/V Lance in September 2013 covered the region north of Svalbard for mooring deployments and transects across the Atlantic Water inflow along the continental slope. Depth-profiles of Chlorophyll a fluorescence were recorded with a Wetlab ECO-AFL/FL fluorometer mounted on the CTD rosette and integrated with the SBE911 system. Fluorometer measurements were calibrated against in situ Chlorophyll a (Reigstad et al., 2023) using linear regression to derive vertical profiles of absolute Chlorophyll a concentrations.
The study was funded by the Fram Centre project A-TWAIN, project no. 66050.

This dataset is a collection of averaged acid-corrected Chlorophyll a (Chla) and phaeopigments, and inorganic nutrient measurements taken as part of the A-TWAIN project during a cruise onboard RV Lance in September 2013, covering the Atlantic Water inflow region north of Svalbard. Water samples were taken from the CTD rosette at 11-12 depths throughout the water column for determination of Chla, and inorganic nutrients (nitrate plus nitrite (NO3− plus NO2−), phosphate (PO43-) and silicic acid (Si(OH)4 )/silicate (SiO2);concentrations in mmol m−3). For Chla, triplicates of 200 ml were filtered onto GF/F glass microfiber filters (Whatman, England) and 10 µm Isopore membrane polycarbonate filters (Millipore, USA), and frozen until further processing back in the laboratory at UiT The Arctic University of Norway. At UiT, samples were extracted in 5ml of methanol in darkness at 4C for ca. 24 h (Holm-Hansen and Riemann, 1978) and measured with a 10-AU Turner fluorometer (Turner, USA). For inorganic nutrients, water samples of 200 mL were collected in acid-washed plastic bottles or in new and rinsed falcon tubes (3x 50 ml) and immediately frozen at -20C until further processing. Following standard methods (Grasshoff et al., 2009) back in the laboratory at UIT The Arctic University of Norway (Tromsø), three replicates were analyzed for each sample. Samples were measured with a Flow Solution IV Analyser (OI Analytical, USA) calibrated with reference sea water (Ocean Scientific International Ltd., UK). The detection limits were 0.02 mmol m−3 for nitrate plus nitrite, 00.1 mmol m−3 for phosphate and 0.07 mmol m−3 for silicic acid. The study was funded by the Fram Centre project A-TWAIN, project no. 66050.
