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.

Hydrographic and biogeochemical data during the Multidisciplinary ecosystem survey in the eastern Indian sector of the Antarctic with a focus on Antarctic krill by R/V Kaiyo-maru in 2018/19.
This is a horizontal velocity dataset measured underway and on CTD stations on the KY1804 cruise leg1 by using SADCP. The raw data were processed by the standard software package from University of Hawaii.
Ground-based radar-sounding surveys were carried out at southern area from Dome Fuji station during the period from 18 december 2018 to 8 January 2019. We used two radar systems as follows. (1) The multi-channel, VHF wideband radar system developed by the University of Kansas for fine-resolution measurements of the interior and based of ice sheets, and (2) the ultra-wideband microwave radar system developed by the University of Alabama for snow and firn measurements. Distance of the survey is 1340km at the southern area from Dome Fuji station, and 546km from the base camp of the JARE60 traverse campaign to ARP2.
The GPS data and photo data of the sampling points of terrestrial photosynthetic organisms (bryiphyta, lichens and algae) were collected in JARE60 activity in the summer season (Dec. 2018-Feb. 2019). The GPS data acquisition were performed by Garmin Gps Map 64S (Garmin Ltd., Kanton Schaffhausen, Switzerland). All sampling points were located in glacier retreat area. Harvested samples are stored at NIPR in freeze condition (-20 degreeC) until these are used for analyses.
Sea-surface gravity and geomagnetic measurements are conducted on board the R/V Shirase in the Southern Ocean. Sea bottom pressure is monitored with a pressure gauge installed and recovered every summer on the sea bottom about 4000 meter deep in the Southern Ocean.
Shallow core drilling was conducted at NDFN, located 50 km south from Dome Fuji station. A 142-m-long core was drilled from 14 to 29 December 2018. The drilled core was cut every 0.5 m due to packing. We recorded weight, length and physical condition of cores in a core log. After the drilling, firn air sampling was conducted at 25 points at a depth of 100m in borehole 100 m from surface. Borehole temperature was recorded at depth of 1, 5, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140 m on 30 December. Temperature at 10 m depth is -56.2 degC.
