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.
- Meiofauna_data_v2017-12-11.xlsx contains all data in separate sheets. The information here is from the “Info” tab.
- Info.csv contains the same information than listed here.
- Columns.csv: Column explanation for datasheets.
- References.csv: Reference list for the dataset.
- Original.csv: Minimally modified non-transformed original data. Used only as a reference to the original data and in quality checks.Relative Ciliata and Rotifera abundances were transformed to estimated absolute abundances (see “Columns” sheet). Some entries, taxa, and ice-cores were removed due to unclarities.
- Transformed.csv: Abundance values transformed to ind/m2 values. Ice-core sections not summed up.
- Compiled.csv: Ice-core sections summed up for each ice-core. Used in the SAMB report.
- Cut10cm.csv: Bering Sea, Barrow, and N-ICE data. Only bottom 10 cm of ice-cores are included. If all of bottom 10 cm was not available, less than that was included. Used in Fig 3, Fig 4 and Fig 6 in the Ecology & Evolution paper. Subset Sec == “bottom 10 cm” before usage for comparison purposes. Note that Fig 3 and 4 in the paper have been created after excluding all ice-core sections other than “bottom 10 cm”.
- Article.all.csv: All data (including RAW columns) for the manuscript. Note that GRAND SUM columns are derived from RAW columns (i.e. the dataset contains duplicates). Used in Table 2 in the Ecology & Evolution paper. This is the most comprehensive and checked dataset.
- Article.groups.csv: Only GRAND SUM abundance columns for the manuscript. Used in Fig 1, Fig 5 and in some statistical tests in the Ecology & Evolution paper.
- Article.per.csv: Percentage data by ice-core for GRAND SUM columns. Used in Fig 7 in the Ecology & Evolution paper.
- Wholecore.csv: Data where the entire ice-core was sufficiently sectioned to enable examining depth distribution of taxa within ice-cores. Absolute values.
- Wholecore.grp.csv: Same than “Wholecore.csv” but presents percentages for each ice-core by group. Used in Fig 2 in the Ecology & Evolution paper.
If you are in doubt which dataset to pick, use “Article_all.csv”. This is the most comprehensive, checked and least summarized dataset.
