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.
Time-series data from moorings covering the Svalbard Branch of the Atlantic Water inflow over the upper continental slope north of Svalbard, Sep 2017 to Nov 2019. 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.
Ocean data from two ocean moorings, M1 and M2. Both were Nansen Legacy gateway moorings deployed in the northern Barents Sea at potential “gateways” of ocean exchange with the north and east. The moorings were equipped with ADCPs measuring ocean currents, and temperature and conductivity-temperature-pressure sensors at various points along the mooring line:
- Conductivity, temperature, and pressure from RBR Concerto and SBE16plus v2 instruments.
- Temperature from RBR Solo instruments.
- Near-surface ocean currents from upward-looking Nortek Signature 500 kHz ADCP instruments.
- Water column currents from upward-looking RDI 150 kHz ADCP instruments.
The current version of the dataset (V1) contains data from the two first deployments of M1 and M2, covering the period from October 2018 to September 2020.
The document “M1_M2_data_processing_details_2018_2020.pdf” contains further details about the data and processing, as well as important information for users of the data.
The Norwegian Polar Institute is the owner of all the instrumentation described in this document, and was responsible for data processing and documentation. Data are freely available under a CC-BY 4.0 license.

Ocean microstructure profiles from a physical oceanography cruise in August-September 2021, in the Nansen and Amundsen Basin on R/V Kronprins Haakon, KH2021710. The data set includes 80 profiles of 1-decibar vertically averaged dissipation rate of turbulent kinetic energy, in situ temperature (ITS-90 scale) and salinity (practical salinity scale).
Quality
Profiles are collected using Sea and Sun Technology vertical microstructure profiler (MSS90L). The first 9 profiles are made with MSS053, the next ones with MSS046. The MSS90L is loosely tethered and is deployed using a winch, electric on board and maunal on the sea ice. Dissipation rate is measured using two airfoil shear probes. Profiles are averages from the two shear probes. The temperature and salinity profiles are measured from the SBE sensors on the same instrument. MSS90L has an unpumped CTD system. Careful corrections for temperature/conductivity sensor time lag and thermal lag were made. Temperature and salinity were corrected after comparison with the ship CTD. An offset of +0.055 is applied for profiles 28:80. Only downcasts from MSS90L are processed using the Sea and Sun technology routines. Resulting profiles are quality controlled, but still require caution from the user. More details are provided in the cruise report.

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):

Data from the A-TWAIN mooring array on the continental slope of the Nansen Basin at 31E
Currently available: 150 kHz ADCP ocean currents, Temperature, and pressure data from four RBR concertos. The latter will be updated to final form once they have been reprocessed incorporating pre-calibration coefficients. In addition, salinity data as well as data from additional CTD sensors will be made available.
Quality
V1: Fully processed ocean currents. Temperature / pressure data from RBR Concertos have undergone basic processing, but based only on pre-deployment calibration coefficients.
CTD data collected during Conflux project cruise in the Barents Sea June 2011. Mostly profiles from 24-hr stations but also along a North-South transect.
Temperature, salinity and other parameters from CTDs, and currents from ADCPs and single-point current meters, from moorings covering the Svalbard Branch of the Atlantic Water inflow over the upper slope north of Svalbard, Sep 2012 to Sep 2103.
Data processed with standard software from the instrument manufacturers, and calibrated with in situ water bottle analysis and post-cruise calibration.
This data set named the Kongsfjorden Transect data is a subset of the UNIS Hydrographic Database (UNIS HD). UNIS HD is a collection of temperature and salinity profiles from the area (1-30°E and 75-81.5°N). The main portion of the Kongsfjorden Transect data were collected during the period 1994-2014 by The University Centre in Svalbard (UNIS), University of Bergen (UiB), Norwegian Polar Institute (NPI), Institute of Oceanology Polish Academy of Sciences (IOPAS) and the Arctic University of Norway (UiT). Additional data in the database have been extracted from other data publishers; the Norwegian Marine Data Centre (NMDC, https://www.nmdc.no/), the International Council for the Exploration of the Sea (ICES) conductivity, temperature and depth (CTD) database (https://ocean.ices.dk/HydChem/), the PANGAEA data publisher (https://www.pangaea.de/), and the database from the project Norwegian Iceland Seas Experiment (NISE; Nilsen et al., 2008).
Quality
Data processed with standard software from the instrument manufacturers, and most of them calibrated with in situ water bottle analysis and post-cruise calibration. However, calibration has not been quality checked in all the data, so use with caution (salinity values in particular).
