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 data set covers the marine biological transect from Kongsfjorden to Fram Strait (KongHau transect) within the framework of the Environmental monitoring of Svalbard and Jan Mayen (http://www.mosj.no/en/) program. The data set covers summers 2009-2014 for nutrients and chlorophyll a (Chl a) and summer 2009-2013 for protist (including phytoplankton and protozooplankton) abundance. The results published in Hegseth et al. 2019 (see the “Citation Custom” field) are based on this data set. Norwegian Polar Institute”s marine database will contain extended data from the KongHau transect, and any users post-2019 are encouraged to use the extended data set instead.
Quality
The data set is compiled in three files:
Protist_abundance_Kongsfjorden2009-2013_Hegseth et al contains protist abundance data in cells per liter for each taxon identified in light microscopy at the Institute of Oceanology, Polish Academy of Science. Through the SampleID column the abundance data set can be linked to the metadata set. The column AphiaID refers to the taxonomic identifier in the World Register of Marine Species (WoRMS).
Nutrients&Chla_Kongsfjorden2009-2014_Hegseth et al contains nutrient data (nitrate (NO3), nitrite (NO2), phosphate (P), silicate (Si) and ammonium (NH4)) in µmol per liter and chlorophyll a data in µg per liter. Through the SampleID column the nutrient and Chl a data set can be linked to the metadata set.
Metadata_Kongsfjorden2009-2014_Hegseth et al contains metadata for nutrients, Chl a and protist abundance. Columns: SampleID = row name in nutrient and Chl a and protist abundance data; Program = name of the program; ship = name of the research vessel; station = standard station name across the MOSJ transect; Year = Year; Latitude = Latitude as decimal degrees; Longitude = Longitude as decimal degrees; Bottom depth = water depth at the respective station; Sampling date = date in yyyy-mm-dd format; Gear = gear used to collect the sample; Depth = Sampling depth; Sample Type = Taxonomy for protist abundance, CHLA for chlorophyll a and Nutrients for Nutrients; Sample staff = person collected the sample; comment = specific comments concerning the sample.
Hourly summarized wet/dry records (as proportion of hour wet) for each individual (salt water immersion data recorded by light-level geolocators deployed on adult breeders).

Abstract:
The ARKXXIV/1 cruise of the German icebreaker Polarstern took place from 20 June to 10 July 2009 and was focused on oceanographic investigations in the northern Nordic Sea. The main work sites were Fram Strait between Svalbard and Greenland and in the Greenland Sea. Hydrographic mesurements during the cruise included the standard section in the nothern Fram Strait along 78°50N, which has been occupied regularly since 1997 (27 stations)
Flux of CH4 emission was observed by the chamber method at the taiga-tundra boundary in the vicinity of Chokurdakh (71 N, 148 E) in northeastern Siberia during the summer from 2009 to 2013. The observation period includes a wetting event with extreme precipitation in 2011. From 2011 on, dissolved CH4 in surface water and soil pore water in wet areas of sphagnum mosses and sedges was analyzed for concentration, delta-13C, and delta-D to discuss fluctuations in the CH4 production and CH4 oxidation processes. In addition, soil incubation experiments under anaerobic and aerobic conditions were conducted to investigate behaviors of isotopic compositions of CH4 in the CH4 production and CH4 oxidation processes and interpret in situ isotopic data. Using the same sampling locations as the anaerobic incubation experiment, phylogenic compositions of methanogenic archaea were analyzed by amplicon sequencing of 16S rRNA gene to discuss CH4 production pathways. This data set shows interannual variations in CH4 flux before and after the wetting event and those in CH4 production and oxidation processes after the wetting event.
