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.
This dataset provides surface elevations of three ice rises, Blåskimen Land (IRD), Kupol Ciolkovskogo (IRB) and Kupol Moskovskij (IRC), around the Fimbul Ice Shelf, in Western Dronning Maud Land.
The digital elevation models (DEMs) were developed using kinematic GPS measurements tied to a local base station on each ice rise. The DEMs are projected to a polar stereographic projection parallel to 71°S (GOCE gravity product (http://www.opengis.net/def/crs/EPSG/0/3031)) was subtracted from the heights above the WGS84 ellipsoid.
The data are provided in MATLAB (.mat) file format. For each ice rise the files are named such as ‘IRB_DEM.mat and ‘IRB_GPS.mat’:
IRB_DEM.mat includes a struct-class variable. XX and YY show the coordinates, and ZZ shows elevations. All are in the unit of meters. IRB_GPS.mat include a struct-class variable. LAT and LON are decimal degrees, and Z is in meters. IRB_DEM.png shows the DEM in color and contours (10 m intervals) together with GPS tracks (white). It is plotted against a local coordinate, which is parallel to EPSG3031 but the origin is the summit of the ice rise.
GPS data for IRD provided here include erroneous data that show (both positive and negative) spikes in the elevations; these data are outliers from adjacent data points, and in some cases the spike height reaches 5-10 m. These spikes appear near the summit and other places. Because the number of erroneous data points is quite small, these features do not significantly affect the DEM.
