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 map service includes many layers of various landforms on the seabed. Landforms formed under the influence of ice, by fluid escape from underlying sediments (pockmarks), gravity (slides), currents or waves are interpreted on the basis of detailed bathymetry data and sediment data.

Black carbon (BC) and light-absorbing iron oxides (FeOx) aerosols affect Earth's energy budget through their strong absorption of solar radiation. FeOx aerosols also can play a role as a nutrient for oceanic phytoplankton and thus potentially affects the global biogeochemical cycles. However, in-situ observation data of atmospheric concentrations and microphysical properties of these light-absorbing aerosols which are required for evaluating their climate effects using global models have been scarce, especially for FeOx aerosols. Here, we summarize and compare the datasets of BC and light-absorbing FeOx from five ground and three aircraft observation campaigns conducted in the East Asian and Arctic regions during the 2009-2018 period by using a modified single-particle soot photometer of the University of Tokyo. In all the campaigns, the majority (> 80%) of FeOx-containing aerosols in 170-270 nm FeOx size range has microphysical features of anthropogenic origin. The particle-size distribution for each of the BC and FeOx was similar among all the datasets, excepting the datasets dominated by fresh urban pollution or pristine arctic free-tropospheric air. The campaign-averaged mass concentration of FeOx (BC) in the East Asian and Arctic regions were ~100-400 (~300-1000) ng/m3 and ~5 (~25) ng/m3, respectively. Despite the large inter-campaign variation of their mass concentration, the campaign-averaged FeOx/BC mass concentration ratio were within a quite narrow range of 0.2-0.5 for all the campaigns. In each campaign, FeOx, BC, and carbon monoxide (CO) were tightly correlated with each other, implying the similarity of spatial distribution of their emission sources.
