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.

Interactions between domesticated escapees and wild conspecifics represent a threat
to the genetic integrity and fitness of native populations. For Atlantic salmon, the recurrent
presence of large numbers of domesticated escapees in the wild makes it necessary
to better understand their impacts on native populations. We planted 254,400 eggs
from 75 families of domesticated, F1‐hybrid, and wild salmon in a river containing upand
downstream traps. Additionally, 41,630 hatchery smolts of the same pedigrees
were released into the river. Over 8 years, 6,669 out‐migrating smolts and 356 returning
adults were recaptured and identified to their families of origin with DNA. In comparison
with wild salmon, domesticated fish had substantially lower egg to smolt survival
(1.8% vs. 3.8% across cohorts), they migrated earlier in the year (11.8 days earlier across
years), but they only displayed marginally larger smolt sizes and marginally lower smolt
ages. Upon return to freshwater, domesticated salmon were substantially larger at age
than wild salmon (2.4 vs. 2.0, 4.8 vs. 3.2, and 8.5 vs. 5.6 kg across sexes for 1, 2, and 3
sea‐winter fish) and displayed substantially lower released smolt to adult survival (0.41%
vs. 0.94% across releases). Overall, egg‐to‐returning adult survival ratios were 1:0.76:0.30
and 1:0.44:0.21 for wild:F1‐hybrid:domesticated salmon, respectively, using two different
types of data. This study represents the most updated and extensive analysis of
domesticated, hybrid, and wild salmon in the wild and provides the first documentation
of a clear genetic difference in the timing of smolt migration—an adaptive trait presumed
to be linked with optimal timing of entry to seawater. We conclude that spawning and
hybridization of domesticated escapees can lead to (i) reduced wild smolt output and
therefore wild adult abundance, through resource competition in freshwater, (ii) reduced
total adult abundance due to freshwater competition and reduced marine survival
of domesticated salmon, and (iii) maladaptive changes in phenotypic traits.
