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.
Monthly values for sea ice extent in the inner part of Kongsfjorden, Svalbard 2003-2019, as percentages of the total surface area during February-June each year. The data file has six columns: a) the year the data connects to, and b)-f) the numbers for maximum fast ice coverage (in percent from the defined observation area, equalling 120 km2) for each month from February to June (2003-2019) in the inner part of Kongsfjorden, derived from manually drawn and digitized ice maps (see above). This inner fjord area is based on a coastline from 1993. Since glaciers have been retreating since then, some new areas developed where there is a potential of sea ice formation. Those areas will be considered in future updates of the dataset. Gaps in some lines in the figure are related to years/months where no data are available. If an observation is missing, data is set to 999.
Land-fast sea ice covers the inner parts of Kongsfjorden, Svalbard, for a limited time in winter and spring months, being an important feature for the physical and biological fjord systems. Monitoring of the Kongsfjorden area has been carried out by the Norwegian Polar Institute (NPI) systematically since 2003 (Gerland and Renner 2007; Pavlova et al. 2019; Gerland et al. 2020). Conception and methodology of the systematic fast-ice monitoring in Kongsfjorden are described in Gerland and Hall (2006), Gerland and Renner (2007), and Pavlova et al. (2019) and include visual sea ice extent observations from the mountain Zeppelinfjellet (mapping) as well as in situ measurements of snow and ice thickness (Gerland and Renner 2007; Pavlova et al. 2019). The monitoring was designed to be relatively inexpensive, robust, and consistent over time. The permanent presence of NPI personnel at the Sverdrup unit in Ny-Ålesund Research Station and daily visits to the observatory on the mountain Zeppelinfjellet just south of Ny-Ålesund enable regular ice extent observations (weather, visibility, and daylight permitting). Data collected within this standardized monitoring programme have contributed to a number of studies (see, e.g. Moe et al. 2012; Johansson et al. 2020). Monitoring of the sea-ice conditions in Kongsfjorden can be used to demonstrate and investigate phenomena related to climate change in the Arctic.
