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.

This data set includes borehole temperatures measured to a depth of 17.5 meters, during the 'HIHAT' project in China, which related to bridge and culvert foundations in seasonal frost regions.
The Austrian Alps are part of the Eastern Alps which consist of three main mountain ranges. The Northern Alps as well as the Southern Alps are predominantly built of limestone and have poor glaciation in spite of high amounts of precipitation (2000-3000 mm/a) due to the fact that they reach elevations of not more than 3000 m. In contrast the Central Alps consist of metamorphic rocks and receive less precipitation, but are glaciated on large areas (highest mountain of Austria: Groglockner, 3797 m). Recent permafrost and rock glaciers are best developed in the Central Alps, where discontinuous mountain permafrost occurs above a mean altitude of 2500 m.
Rock glaciers were mapped from aerial photographs (different years, most of them 1980-1990) completely covering the area described above. The inventory comprises 1451 rock glaciers with data on their horizontal and vertical position, activity, and morphometric characteristics of each rock glacier. The distinction between active and inactive rock glaciers within the activity class 'intact' was not possible due to the quality of the photographs. Only 19 % of the rock glaciers were classified as intact, while 81 % are relict ones and in most cases of Late Glacial age (a great part of the investigated is situated below present day lower limit of permafrost). In detail the inventory contains information of the following parameters:
1: River basin
2: Number of rock glacier according to river basins
3: Topographic name out of the official map 1:50.000
4: Mountain group
5: Number of official map 1:50.000
6: Number of official aerial photograph map
7: Exposure (8 classes)
8: Lower limit of rock glacier (m above sea level)
9: Maximum length (m, in estimated flow direction)
10: Maximum width (m)
11: Activity (2 classes: intact, relict=fossil)
12: Highest point of the catchment area of the rock glacier
(m above sea level)
13: Difference between 12 and 8 (m)
Geographic coordinates of coverage as listed in the GGD inventory are approximate. These data are presented on the CAPS Version 1.0 CD-ROM, June 1998. The inventory does not include measurements on dynamics of rock glacier permafrost.
