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.
During the first Chinese Arctic Scientific Expedition between July and September in 1999, a ground radio-echo sounding survey was carried out, using a new type of ice penetrating radar system with antenna center frequencies of between 100 and 200 MHz, for detecting the sea ice thickness in Arctic Ocean. In addition, the radar sounding yielded a subtle morphology on the bottom of sea ice in summer in Arctic Ocean.

Abstract:
The geochemical characteristics of the Bering Sea and Chukchi Sea CO2 flux and carbon.Time: during the period from July 2, 1999 to September 6, 1999 in the Chinese first Arctic scientific expedition.
XBT and XCTD probes were droped along a section north of the Weddell Sea, Antarctica, to measure temperatures and salinities at the upper ocean (above 1000m), during the austral summer of 1998/1999.

Abstract:
During the first voyage of Chinese National Arctic Research Expedition, in vivo
fluorescence and absolute concentration of Chl-a was determined by the
extraction method with TURNER DESIGN Field Fluorometer (Model 10-005R) as the
basic data for the MEBCS project (China-Korea cooperation project) at 90 sites
along the voyage line and in Bering Sea and Chuckchi Sea.

Abstract:
During the first voyage of Chinese National Arctic Research Expedition,we use automatic station to get the weather information, including pressure, cloud, temperature, humidity and precipitation. Every one hour the program writed the weather data to harddisk.
A series of measurements in water temperature, conductivity and depth was carried out during the austral summer of 1998/99 within and the north of Prydz Bay, the southern Indian Ocean.34 oceanographic stations were successfully completed and 3.77MB CTD data were obtained.

Abstract:
1 temperature and salinity are the two basic physical ocean water mass, the navigation observation and supplemented by other data, we can know the dividing of the Kuroshio, Oyashio, North Pacific Ocean and the Arctic Ocean water masses, determine the front position, intensity, especially the sub Arctic front, and their. 2 the study of air sea interface water vapor mass flux and energy flux. 3 for the observation of other subjects such as CO2 flux, radiation chemistry, marine biology, and provide basic data. 4 for the use of satellite data retrieval. SST can provide calibration based on.
