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 and phrases embedded in quotation marks. Logical operators include AND, OR and NOT. Remember to add space around operators. Text strings that are not quoted are trated as separate words and will match any of the words (i.e. assuming the OR operator). E.g. in order to find WMO synoptic weather station data from Verlegenhuken use the search phrase: [synop AND verlegenhuken]. Searches are case insensitive.
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.
Collections
Collections allows the user to search in subsets of the existing catalogue. The collections are primarily data management projects that have been incorporated in the ADC catalogue after the project has ended. In this context the ADC is the long term access solution for these data. The collections currently served through ADC include (datasets may belong to multiple data collections):
ADC is the full collection of this service CC is the CryoClim collection
In order to search a specific data collection select that collection. If no data collection is selected all collections are searched.
AeN are data related to the Nansen Legacy project and are better explored through the SIOS Data Access Point using the collection defined there which is available through this URL.
SIOS, InfraNOR, SIOSCD, SIOSAP, SESS_* are collections related to SIOS. These are better explored through the SIOS Data Access Portal
Some cleaning is pending between InfraNOR and SIOSIN, for some of the SESS collections.
Citation of data and service
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)
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 Norwegian Meteorological Institute/Arctic Data Centre.
The dataset consists of 36-h filtered basal melt rates (m/yr) derived from a phase-sensitive radar (ApRES) on Fimbulisen ice shelf, Dronning Maud Land (70 deg S, 0 deg E). If you use the dataset in presentations or publications please also refer to the paper (Lindbäck et al., 2023, in review), where the data is described in more detail. The dataset will be updated if the quality of the data is improved or if new datasets become available.
Atmospheric profiles of temperature, humidity, wind speed and direction from radiosondes (Vaisala RS92-SGPL) released from ship, R/V Lance. A total of 27 radiosonde launches were conducted during the Fram Strait 2017 cruise from August 25th to 10th September 2017. Sondes were launched one or two times a day around 00 UTC and 12 UTC.
Quality
Data were logged and processed using the DigiCora program from Vaisala
The data have been collected during with RV Lance 30 July-2 August 2017. Samples have been collected using baited traps in the glacier bay in front of Kronebreen in the inner part of Kongsfjorden.
Quality
Sampling method:
Benthic amphipods were caught in baited traps, in strings of five traps each deployed overnight from Polarcirkel at different locations in the glacial bay outside Kronebreen in. The baited traps consisted of plastic pipe (20 cm long, 10 cm in diameter) with a funnel attached to one end and a removable net (mesh size: 1 mm) on the other. Bait was raw chicken meat packed in fine-mesh bags to prevent the amphipods from getting access to it.
Analyse method:
The collected species were identified under a stereomicroscope.

The dataset consists of ice flow and surface mass balance derived from stake measurements on Nivlisen ice shelf, Dronning Maud Land (70 deg S, 12 deg E). Velocity azimuth is clockwise from the true north in degrees.
If you use the dataset in presentations and publications please also refer to to the peer-reviewed paper (Lindbäck et al., 2019, https://doi.org/10.5194/tc-2019-108), where the data is described in more detail. The dataset will be updated when the quality of the data is improved or if new datasets become available.
This work was part of the MADICE (Mass balance, dynamics, and climate of the central Dronning Maud Land coast, East Antarctica) project co-led by the Norwegian Polar Institute in Norway and National Centre for Polar and Ocean Research in India (https://www.npolar.no/prosjekter/madice/).
Biomarker (HBIs) and stable isotope data (d18O, d13C) from sediment cores HH15-06GC and JR142-11GC. The data originates from two marine sediment cores northeast of Svalbard. Core JR142-11GC was obtained using a gravity corer during a cruise with RSS “James Clark Ross” carried out by British Antarctic Survey in 2006. Core HH15-06GC was also obtained using a gravity corer during a cruise with RV “Helmer Hanssen” carried out by University Centre in Svalbard 2015. The research aims were 1) to investigate cryosphere-ocean linkages during the final decline of the Barents Sea Ice Sheet (BSIS) which may serve as an analogue of modern West Antarctic Ice Sheet (WAIS), and 2) obtain baseline values for natural fluctuations of ocean temperature and sea-ice evolution in northern Barents Sea – Svalbard region.
