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 SAON Data Portal.
Brief user guide
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 through the drop down menu above the text field. Text strings that are not quoted are treated as separate words and will match any of the words (i.e. assuming the OR operator). Phrases may be prefixed with '-' to indicate no occurence of the phrase in the results.
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.
Datasets collected during TW-ICE cruise to Kongsfjorden in July 2017. The datasets contain measurements close to glacier fronts taken with a research vessel and helicopter, and have been published in Halbach et al. (2019; see the “Citation Custom” field).
The datasets are compiled following files:
Nutrient data.csv Nutrient measurements together with station metadata. Columns: station = station name; vessel = either the research vessel (Lance) or helicopter; lon = longitude as decimal degrees (WGS84); lat = latitude as decimal degrees (WGS84); date = date in ISO8601 format; area = zone used in the article; dist = distance from the closest glacier front in km; depth = bottom depth in m at the station; from = the water depth from which the sample was collected in m; sal = salinity from the closest CTD; temp = water temperature from the closest CTD; type = water type classification based on salinity and temperature (see the article); ctd.name = name of the closest CTD cast; chla = chlorophyll a in mg m-3; phaeo = phaeophytin in mg m-3; tsm = total suspended matter in g m-3; no2 = nitrite concentration in mmol m-3; no3 = nitrate concentration in mmol m-3; sioh4 = silicate concentration in mmol m-3; po4 = phosphate concentration in mmol m-3; nh4 = ammonium concentration in mmol m-3; urea = urea concentration in mmol m-3.
Phytoplankton data.csv Phytoplankton taxonomy data together with station metadata. Columns: station = station name; lon = longitude as decimal degrees (WGS84); lat = latitude as decimal degrees (WGS84); date = date in ISO8601 format; area = zone used in the article; dist = distance from the closest glacier front in km; depth = bottom depth in m at the station; from = the water depth from which the sample was collected in m; sal = salinity from the closest CTD; temp = water temperature from the closest CTD; type = water type classification based on salinity and temperature (see the article); ctd.name = name of the closest CTD cast; group = coarse functional grouping; species = species or taxa; abundance = abundance of the species in cells dm-3.
CTD data.json CTD data in a list format. See the oce-class (https://www.rdocumentation.org/packages/oce/versions/1.0-1/topics/ctd-class) documentation for the oce R package for further details on formatting. The results are from a Sea-Bird SBE 9 (Lance) and Hydro-Bios Multi-Water-Sampler (helicopter).
Water type data.csv Water type classification data together with station metadata. Columns: row_id = unique ID for a CTD cast; station = station name; vessel = either the research vessel (Lance) or helicopter; lon = longitude as decimal degrees (WGS84); lat = latitude as decimal degrees (WGS84); date = date in ISO8601 format; area = zone used in the article; depth = bottom depth in m at the station; ctd.name = name of the closest CTD cast; type = water type classification based on salinity and temperature (see the article); freq = frequency of 1 decibar bins containing the given water type; per = percentage of 1 decibar bins containing the given water type as compared to total number of bins for a CTD cast.
Mixed layer data.csv Mixed layer data. Columns: station = station name; ctd.name = name of the closest CTD cast; pres = pressure of the maximum N2 bin in decibars; sal = salinity at the maximum N2 depth; temp = water temperature at the maximum N2 depth in Celsius; rho = potential water density at the maximum N2 depth; n2 = the maximum Brunt-Väisälä-frequency during CTD cast close to the surface; mld = estimated mixed layer depth based on maximum N2 in m.
Euphotic depth data.csv Euphotic depth data. Columns: station = station name; depth = depth of the estimated euphotic depth in m; par = photosynthetically active radiation at the euphotic depth; spar = photosynthetically active radiation on the surface; per = percentage ratio between par and spar.
