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.

The survey indices by age group for bottom trawl and acoustic estimates for haddock from the winter survey (January-March) in the Barents Sea are calculated as described in Mehl et al. 2016 (bottom trawl) and Mehl et al. 2018 (acoustic). Mean length and weight at age is also calculated. Updated data series are provided in the annual survey reports (e.g. Mehl et al. 2019). The series go back to 1981, but StoX estimates go back only to 1994. The survey has been a Joint Norwegian-Russian one from 2000 onwards except in the years 2006, 2007 and 2017.
The survey area is divided into eight main areas and 26 strata. In 2014, the investigated area was enlarged by three new strata in northwest, 24-26. These strata are, however, not included in the standard calculations of indices. Note also that prior to 1994, the area covered was smaller and no adjustments have been made for that. In the early period (1981-1995) there were also some gear changes, for which adjustments have been made, these changes are also described in the reports referred to.
In 1997, 1998 and 2007 only the Norwegian EEZ (NEZ) and parts of the Svalbard area (S) was covered. The indices for cod and haddock have therefore been raised to also represent the Russian EEZ (REZ) (Mehl et al. 2016, 2018).
In 2006, there was not a complete coverage in southeast due to restrictions. The observations in the partially covered strata 7 were extrapolated to the full strata, and the observations in the partially covered strata 13 were extrapolated to the same area as covered in 2005. In 2012 the coverage was incomplete in the eastern areas, and the cod and haddock swept area estimates within the covered area were raised by the “index ratio by age” observed for the same area in 2008-2011 (ICES 2012). The scaling factor (“index ratio”) for estimating adjusted total from <Total – area D’> was the average ratio by age for Total/(Total – area D’) in the years 2008-2011 (Aglen et al. 2012).
In 2017, the Norwegian vessel was not allowed to operate south of 70º 10’ N and west of 41º 00 º E, and no Russian vessel participated in the survey. Only a small part of strata 7 was covered, and strata 13, 15, 17 and 20 were not covered. The cod, haddock, Greenland halibut and beaked redfish swept area estimates and cod and haddock acoustic estimates within the covered area were raised following the same procedure as for 2012. The scaling factor for estimating adjusted total from <Total –strata 7 > was the average ratio by age for Total/(Total – (strata 7+13+15+17+20)) swept area indices in the years 2014-2016.
All these adjustments are included in the StoX projects used for the calculations.
This dataset includes Geophysical Institute (GFI), University of Bergen mooring SVI199704_C data. The mooring consists of 3 inst.

Harp seals (Phoca groenlandica) from the Barents Sea were analyzed for blubber levels of polychlorinated biphenyls(PCBs), polychlorinated camphenes (PCCs; toxaphenes), DDT and its metabolites, hexachlorobenzene (HCB), hexachlorocyclohexanes(HCHs), and the cyclodiene pesticides, including dieldrin, endrin, and the chlordanes. Also, the hepatic cytochrome P450(CYP) enzyme activities were measured to assess a possible relation between CYP activities and pesticide levels. Furthermore, thebioaccumulation potential and persistency of these compounds were evaluated. PCCs were the dominant contaminants, exceedingthe PCB concentrations. Individual PCC congener levels (Tox 26 and 50) were fourfold greater than those in the Canadian Arcticand 20-fold greater than those in seals from the west coast of Svalbard, suggesting that the Barents Sea is exposed to PCCs by alocal source. The biomagnification factor and the metabolic index were greatest for p,p-DDT, HCB, b-HCH, and the chlordanestrans-nonachlor and U82. The other pesticides showed lesser values, suggesting metabolism. The ethoxyresorufin-O-deethylationactivity (CYP1A) was high and not correlated with any of the pesticides, whereas a high correlation (r2 adjusted . 50%) was foundbetween the PCCs and testosterone 6-b hydroxylation activities (CYP3A). This suggests an induction of CYP3A-like activity byPCC exposure.
The principal aim of this study was to describe the vocalisations produced by the largely unstudied white-whale population in Svalbard, Norway. Fieldwork was conducted during the period 1–19 August 1997 in Van Keulenfjorden in Svalbard, Norway (77°34’N, 15°30’E). All recordings were made with a Brüel and Kjær 8106 hydrophone and a Sony TCD-D10 PROII DAT-recorder. A total of 4 h and 25 min of recordings, containing more than 7000 white whale vocalisations, were documented. It was found that Svalbard’s white whales produced most of the vocalisations that have been documented in other populations, but they also displayed minor vocal novelties and differences. A subjective classification suggested 21 call types, which were dominated by a variety of whistles. A statistical classification (cluster analyses) produced 11 groupings (after exclusion of general pulsed call types), which contained fairly logical grouping of the subjectively determined call types. However, neither method of classification employed was considered ideal for classifying white-whale vocalisations because of the highly graded nature of the calls. The white whales in this study were most vocal during milling and joining behaviours. A surprising result in this study was how little time white whales in this area spent vocalising. Their relative silence could possibly be: (1) an anti-predator strategy in response to killer whales (Orcinus orca); (2) a result of the type of schools encountered during this study (all-male grouping); (3) a by-product of the presence of the research boat in an area where whales are not accustomed to boat traffic; or (4) a result of the limited behavioural repertoire covered in this study. More extensive studies of acoustic behaviour of this population, which include various age and sex classes, with broader seasonal coverage that includes more potential behavioural contexts, are required before firm conclusions can be made regarding geographic trends in white-whale acoustic behaviour.
